The iOS Developer's Toolkit: Essential Skills & Technologies for Success in 2025
To successfully hire iOS developers, it's crucial to understand the modern toolkit they need to excel. The landscape of iOS development is constantly evolving, demanding proficiency in a range of skills and technologies. This article outlines the essential competencies for iOS developers in 2025.
Knowing these will help you evaluate candidates, whether you're considering freelance vs. full-time hires, and will also inform your understanding of the iOS app development process. Let's dive into what makes a skilled iOS developer in today's tech landscape.
Core Programming Languages for iOS Development
The foundation of any iOS developer's skill set starts with programming languages. While the ecosystem has evolved significantly over the years, two languages remain central to iOS development. Understanding both is crucial for any developer working in this space.
Swift: The Present and Future
Swift has become the heartbeat of modern iOS development. Apple introduced it in 2014, and it's now the go-to language for building new iOS applications. What makes Swift so special? It's designed with safety and performance in mind.
Think of Swift as a language that catches your mistakes before they become problems. Its type safety means you're less likely to encounter runtime crashes. The compiler acts like a helpful assistant, pointing out potential issues as you write code. This makes development faster and more reliable.
Swift's syntax is clean and expressive. Where older languages might require five lines of code, Swift often accomplishes the same task in two or three. This isn't just about saving keystrokes – it's about making code easier to read and maintain. When you come back to a project six months later, you'll thank yourself for using Swift.
Performance is another key advantage. Swift code runs fast, often matching or exceeding the speed of C-based languages. For mobile apps where every millisecond counts, this efficiency matters. Users expect smooth scrolling, instant responses, and fluid animations. Swift delivers on these expectations.
The language continues to evolve with each release. Recent versions have introduced powerful features like async/await for handling asynchronous operations. These additions make complex tasks simpler and code more readable. Staying current with Swift's evolution is part of being a competent iOS developer.
Objective-C: Understanding Legacy Code
While Swift is the future, Objective-C remains relevant in 2025. Many established apps still have significant portions written in Objective-C. Large companies with apps that have been around for a decade or more often have millions of lines of Objective-C code.
Understanding Objective-C isn't just about maintaining old code. It's about being able to work with mixed codebases where Swift and Objective-C coexist. Many iOS frameworks still expose Objective-C APIs, and knowing how to bridge between the two languages is valuable.
The syntax of Objective-C can seem unusual at first, especially if you're coming from other languages. Its message-passing style and square bracket notation take some getting used to. But once you understand the patterns, you'll see why it was revolutionary for its time.
Developers who can work with both languages are particularly valuable. They can modernize legacy codebases gradually, converting Objective-C to Swift where it makes sense. This skill becomes crucial when working with established companies that can't afford to rewrite their entire app from scratch.
Essential iOS Frameworks and SDKs
Building iOS apps requires more than just knowing programming languages. Developers need to master various frameworks and SDKs that provide the building blocks for app functionality. These tools handle everything from user interfaces to data storage and networking.
UI Development: UIKit and SwiftUI
User interface development sits at the heart of iOS app creation. Two frameworks dominate this space: UIKit and SwiftUI. Each has its strengths, and modern developers need to understand both.
UIKit has been the standard for iOS UI development since the beginning. It's a mature, battle-tested framework that can create any interface you can imagine. UIKit uses an imperative approach – you tell it exactly what to do, step by step. This gives you precise control over every aspect of your interface.
Working with UIKit means understanding view controllers, views, and the responder chain. You'll build interfaces by combining standard components like buttons, labels, and table views. Custom interfaces require diving deeper into Core Animation and Core Graphics. The learning curve can be steep, but the control you gain is unmatched.
SwiftUI represents Apple's vision for the future of UI development. Introduced in 2019, it takes a declarative approach. Instead of telling the system how to build your interface, you describe what you want. SwiftUI figures out the rest. This makes common tasks much simpler and code more maintainable.
The beauty of SwiftUI lies in its simplicity for standard interfaces. Building a list that updates automatically when data changes takes just a few lines of code. Preview functionality lets you see changes instantly without running your app. It's a productivity boost for many common scenarios.
Choosing between UIKit and SwiftUI isn't always straightforward. New projects targeting recent iOS versions can fully embrace SwiftUI. But apps supporting older iOS versions or requiring complex custom interfaces might stick with UIKit. Many projects use both, leveraging each framework's strengths where appropriate.
Data Management: Core Data and Alternatives
Every app beyond the simplest utility needs to store data. Core Data has long been Apple's solution for local data persistence. It's a powerful framework that goes beyond simple storage, offering features like data modeling, validation, and automatic migration.
Core Data shines when you need to manage complex object graphs. Think of an app that tracks projects, tasks, and team members with relationships between them. Core Data handles these relationships elegantly, letting you focus on your app's logic rather than database management.
The framework integrates deeply with the iOS ecosystem. It works seamlessly with iCloud for syncing data across devices. Memory management is handled automatically, preventing common issues like retain cycles. For apps that fit its model, Core Data is hard to beat.
But Core Data isn't always the right choice. Its learning curve can be steep, and it might be overkill for simple storage needs. This is where alternatives come in. Realm offers a simpler API while still providing powerful features. SQLite gives you direct database access when you need fine-grained control.
The key is choosing the right tool for your needs. A note-taking app might use Core Data for its rich text handling and sync capabilities. A game might use simple file storage for high scores. Understanding the options and their trade-offs is part of being an effective iOS developer.
Networking: URLSession and Third-Party Libraries
Modern apps rarely work in isolation. They connect to servers, download content, and sync data with cloud services. URLSession is iOS's built-in solution for network communication. It handles everything from simple downloads to complex authentication flows.
URLSession provides a solid foundation for networking. It supports various HTTP methods, handles cookies and caching automatically, and integrates with the system's network activity indicator. For basic needs, it's often all you need. The API is straightforward for simple requests but flexible enough for complex scenarios.
Background sessions are where URLSession really shines. Your app can start a download and continue even if the user switches to another app. The system manages these transfers, waking your app when they complete. This creates a smooth user experience for long-running operations.
While URLSession is powerful, many developers use third-party libraries for convenience. These libraries provide higher-level abstractions that make common tasks easier. They often include features like automatic retry logic, request queuing, and simplified JSON parsing.
The choice between URLSession and third-party libraries depends on your project's needs. For simple apps or those with unique requirements, URLSession might be perfect. For rapid development or when working with complex APIs, a library can save significant time.
Concurrency: Grand Central Dispatch (GCD) and Swift Concurrency (async/await)
Mobile users expect responsive apps. Nothing frustrates users more than an interface that freezes while loading data. This is where concurrency comes in – the ability to do multiple things at once. iOS provides two main approaches: Grand Central Dispatch and Swift's modern concurrency features.
Grand Central Dispatch has been the workhorse of iOS concurrency for years. It lets you run code on background queues, keeping your main thread free for UI updates. The concept is simple: heavy work happens in the background, UI updates happen on the main thread. GCD makes this pattern easy to implement.
Working with GCD means understanding queues and dispatch groups. You'll learn to balance performance with resource usage. Too many concurrent operations can overwhelm the device. Too few, and you're not taking full advantage of modern multi-core processors. Finding the right balance is key.
Swift's async/await syntax, introduced recently, makes asynchronous code look and behave like synchronous code. This dramatically improves readability. What once required nested callbacks now flows naturally from top to bottom. Error handling becomes straightforward with standard try/catch blocks.
The new concurrency model goes beyond syntax improvements. It includes concepts like actors for safe concurrent access to shared state. Task groups let you manage multiple related operations. These features help prevent common concurrency bugs like race conditions and deadlocks.
Modern iOS developers need to understand both approaches. Existing codebases often use GCD extensively. New code can leverage async/await for cleaner, more maintainable solutions. The two systems work together, so you're not forced to choose one or the other.
Core Animation & Core Graphics
Visual polish separates good apps from great ones. Core Animation and Core Graphics give developers the tools to create stunning visual effects and custom graphics. These frameworks power everything from simple button animations to complex data visualizations.
Core Animation makes it easy to add motion to your app. Want a button to pulse when tapped? Core Animation handles it. Need a smooth transition between screens? Core Animation has you covered. The framework handles the complex math of interpolation and timing, letting you focus on the creative aspects.
The power of Core Animation lies in its layer-based approach. Every view in iOS has a layer that can be animated independently. You can animate position, size, rotation, opacity, and more. Combining multiple animations creates rich, engaging effects that delight users.
Core Graphics takes you deeper into custom drawing. When standard UI components aren't enough, Core Graphics lets you draw exactly what you need. This might be custom charts, unique progress indicators, or artistic effects. The framework provides low-level drawing primitives that give you complete control.
Understanding these frameworks helps you implement designer visions accurately. That subtle shadow, the perfect curve, or the smooth gradient – Core Graphics makes them possible. Performance considerations matter here. Efficient drawing code keeps your app responsive even with complex visuals.
Specialized Frameworks (ARKit, Core ML, MapKit, StoreKit)
iOS includes specialized frameworks for specific features. Not every app needs these, but knowing they exist and when to use them is valuable. These frameworks let you add advanced capabilities without building everything from scratch.
ARKit brings augmented reality to iOS apps. It handles the complex task of understanding the physical world through the camera. You can place virtual objects in real spaces, create immersive experiences, or build practical tools like measurement apps. The framework handles device tracking, scene understanding, and rendering integration.
Core ML enables on-device machine learning. You can run sophisticated models for image recognition, natural language processing, or custom predictions. The framework optimizes models for iOS devices, ensuring good performance and privacy. Users appreciate features that work without sending data to servers.
MapKit provides mapping and location services. Beyond showing maps, it handles route planning, location search, and custom annotations. Whether you're building a delivery app or a location-based game, MapKit provides the geographic foundation. Integration with Apple Maps gives users a familiar experience.
StoreKit manages in-app purchases and subscriptions. It handles the complex process of payment processing, receipt validation, and subscription management. The framework ensures secure transactions while providing hooks for your app to deliver purchased content. Understanding StoreKit is crucial for apps with premium features.
Key Development Tools and Environment
The right tools make development efficient and enjoyable. iOS developers work with a suite of tools that handle everything from writing code to debugging complex issues. Mastering these tools is as important as knowing the programming languages themselves.
Xcode: The Integrated Development Environment (IDE)
Xcode is the command center for iOS development. It's where you write code, design interfaces, test your app, and submit to the App Store. Understanding Xcode deeply makes you a more productive developer. The IDE packs powerful features that streamline the entire development process.
The code editor in Xcode goes beyond simple text editing. It provides intelligent code completion that understands your project's context. Real-time syntax checking catches errors as you type. Refactoring tools let you rename variables or extract methods across your entire codebase safely.
Debugging in Xcode is a powerful experience. You can set breakpoints to pause execution and examine program state. The visual debugger shows your view hierarchy, making layout issues easy to spot. Memory debugging tools help track down leaks and excessive allocations. These features turn mysterious crashes into solvable problems.
Xcode's testing infrastructure supports both unit tests and UI tests. You can write tests that verify your code works correctly and your interface responds properly. Continuous integration features run these tests automatically, catching issues before they reach users. Test coverage reports show which code paths need more attention.
The performance tools in Xcode deserve special mention. Instruments lets you profile your app's CPU usage, memory allocation, and energy consumption. You can identify bottlenecks and optimize critical paths. This attention to performance creates apps that feel fast and responsive.
Interface Builder (Storyboards & XIBs)
Interface Builder provides a visual way to design your app's interface. Instead of writing code to create every button and label, you can drag and drop components onto a canvas. This visual approach makes it easier to see how your interface will look and behave.
Storyboards show your entire app flow in one place. You can see how screens connect and visualize user navigation paths. This bird's-eye view helps you understand and improve your app's structure. Segues between screens are configured visually, reducing boilerplate code.
XIB files offer a more focused approach. Each XIB typically represents a single view or view controller. This modularity makes them easier to manage in large teams where multiple developers work on different screens. XIBs load faster than storyboards, which can matter for complex apps.
The debate between Interface Builder and programmatic UI creation continues in the iOS community. Interface Builder excels for standard layouts and rapid prototyping. Programmatic approaches offer more control and easier version control integration. Most projects benefit from using both approaches where they make sense.
Auto Layout integration in Interface Builder deserves special attention. You can create responsive layouts that work across all iOS devices. The visual constraint system makes it clear how views relate to each other. This visual approach to layout is often easier than writing constraint code.
Version Control: Git and Platforms (GitHub, GitLab, Bitbucket)
Modern software development is collaborative, and version control makes collaboration possible. Git has become the standard for tracking code changes and coordinating team efforts. iOS developers need to be comfortable with Git workflows and best practices.
Understanding Git goes beyond basic commands. You need to grasp concepts like branching strategies, merge conflicts, and rebasing. Good commit messages tell the story of your code's evolution. Clean commit history makes debugging easier when issues arise months later.
Platforms like GitHub, GitLab, and Bitbucket add collaboration features on top of Git. Pull requests facilitate code review, ensuring quality and knowledge sharing. Issue tracking keeps development organized. Continuous integration pipelines run tests automatically. These platforms transform Git from a version control tool into a complete development workflow.
Code review through pull requests is particularly valuable. Having teammates review your code catches bugs, improves code quality, and spreads knowledge across the team. Learning to give and receive constructive feedback is a crucial skill. The best developers see code review as a learning opportunity, not criticism.
Git's integration with Xcode continues to improve. You can perform most Git operations without leaving the IDE. Visual diff tools show exactly what changed. Blame annotations reveal who wrote each line and why. This integration keeps you in your development flow.
Dependency Managers (Swift Package Manager, CocoaPods)
Modern apps rely on third-party libraries for common functionality. Dependency managers handle downloading, updating, and integrating these libraries. They save time and reduce errors compared to manual integration.
Swift Package Manager (SPM) is Apple's official solution. It's integrated directly into Xcode and uses Swift's package manifest format. SPM's simplicity is its strength – adding a dependency often takes just a few clicks. The tool handles version resolution and ensures compatible dependencies.
CocoaPods paved the way for iOS dependency management. It has a massive ecosystem of available libraries. The Podfile format is straightforward, and the tool handles complex dependency graphs well. Many established projects still use CocoaPods, making it important to understand.
Choosing between dependency managers often comes down to library availability and team preferences. SPM is gaining ground rapidly, but some libraries only support CocoaPods. Some teams use both, choosing the best tool for each dependency. Understanding both tools gives you flexibility.
Beyond choosing a tool, understanding dependency management best practices matters. Keeping dependencies updated prevents security issues but can introduce breaking changes. Locking versions ensures consistent builds across team members. Evaluating dependencies carefully prevents bloat and maintenance headaches.
Debugging and Profiling Tools (Instruments, Xcode Debugger)
Finding and fixing issues is a core development skill. iOS provides sophisticated tools for debugging code and profiling performance. Mastering these tools transforms frustrating bug hunts into systematic problem-solving.
The Xcode debugger is your first line of defense against bugs. Breakpoints let you pause execution and examine program state. Conditional breakpoints trigger only under specific circumstances. Watchpoints alert you when variables change. These features help you understand exactly what your code is doing.
LLDB, the underlying debugger, offers powerful command-line features. You can evaluate expressions, modify variables, and even inject code while your app runs. Understanding LLDB commands gives you debugging superpowers. Complex issues that seem impossible through the GUI become solvable.
Instruments takes you beyond debugging into performance analysis. The Time Profiler shows where your app spends its time. The Allocations instrument tracks memory usage over time. Energy diagnostics help create battery-efficient apps. Each instrument provides insights that lead to better apps.
Memory debugging deserves special attention. iOS devices have limited memory, and poor memory management leads to crashes. Instruments can detect leaks, abandoned memory, and retain cycles. The visual memory graph makes complex object relationships understandable. These tools are essential for creating stable apps.
Understanding Design Principles and Guidelines
Technical skills alone don't create great apps. Understanding design principles ensures your apps feel at home on iOS. Apple has strong opinions about how apps should look and behave. Following these guidelines creates apps users love.
Apple's Human Interface Guidelines (HIG)
The Human Interface Guidelines are Apple's blueprint for creating intuitive iOS apps. They cover everything from navigation patterns to icon design. Understanding and following the HIG is crucial for creating apps that feel native to the platform.
The guidelines emphasize clarity, deference, and depth. Clarity means your app's purpose is immediately obvious. Deference means the interface gets out of the way and lets content shine. Depth provides visual layers that help users understand hierarchy. These principles guide every design decision.
Navigation patterns in the HIG deserve careful study. Tab bars, navigation controllers, and modal presentations each have specific uses. Using the wrong pattern confuses users and makes your app feel foreign. Consistent navigation creates confident users who can focus on their tasks.
The HIG covers platform-specific features extensively. How should your app handle Dynamic Type for accessibility? When should you use haptic feedback? How do you design for both portrait and landscape orientations? The guidelines provide clear answers based on extensive user research.
Following the HIG doesn't mean every app looks the same. The guidelines provide a framework for consistency while allowing creativity. The best apps respect platform conventions while expressing their unique personality. This balance creates apps that are both familiar and memorable.
UI/UX Design Fundamentals
While developers aren't usually designers, understanding design fundamentals improves collaboration and implementation. Basic design knowledge helps you make better decisions when designers aren't available. It also helps you provide valuable feedback during the design process.
Visual hierarchy guides users through your interface. Size, color, and spacing create relationships between elements. Important actions should be prominent. Related items should be grouped. Understanding these principles helps you implement designs that guide users naturally.
Color theory affects both aesthetics and usability. Colors convey meaning and emotion. They also need sufficient contrast for readability. iOS's system colors adapt to light and dark modes automatically. Using these colors ensures your app looks good in any context.
Typography is more than choosing fonts. It's about creating readable, scannable text that serves your users. iOS provides system fonts optimized for screens. Dynamic Type lets users adjust text size for their needs. Respecting these preferences creates inclusive apps.
Interaction design focuses on how users engage with your app. Every tap, swipe, and gesture should feel natural and provide feedback. Animations should be purposeful, not decorative. Loading states keep users informed. These details separate professional apps from amateur efforts.
App Architecture Patterns (MVC, MVVM, VIPER)
Good architecture makes apps maintainable and scalable. iOS developers work with several architectural patterns, each with strengths and trade-offs. Understanding these patterns helps you organize code effectively and work efficiently in teams.
Model-View-Controller (MVC) is iOS's traditional pattern. Models hold data, views display it, and controllers coordinate between them. MVC's simplicity makes it easy to understand. But controllers often become massive, handling too many responsibilities. This "Massive View Controller" problem led to alternative patterns.
Model-View-ViewModel (MVVM) addresses MVC's shortcomings by introducing view models. These objects prepare data for display, keeping controllers focused on coordination. MVVM works particularly well with reactive programming and data binding. SwiftUI's design philosophy aligns closely with MVVM principles.
VIPER takes separation further with five distinct components. View, Interactor, Presenter, Entity, and Router each have specific responsibilities. This separation makes testing easier and responsibilities clearer. But VIPER's complexity can be overkill for simple apps.
Choosing an architecture depends on your app's complexity and team size. Simple apps might thrive with basic MVC. Complex apps benefit from MVVM or VIPER's organization. The key is consistency – mixing patterns within an app creates confusion. Pick an approach and stick with it.
Modern iOS development often combines patterns pragmatically. You might use MVVM for complex screens and simple MVC for basic ones. The goal is maintainable code, not architectural purity. Understanding multiple patterns lets you choose the right tool for each situation.
Essential Soft Skills for iOS Developers
Technical skills get you in the door, but soft skills determine your success. iOS development is rarely a solo activity. You'll work with designers, product managers, and other developers. These interactions require skills beyond coding.
Problem-Solving and Analytical Thinking
Every day brings new challenges in iOS development. A layout that works perfectly on one device breaks on another. An API returns unexpected data. Users report crashes you can't reproduce. Strong problem-solving skills turn these frustrations into opportunities.
Effective problem-solving starts with understanding the issue fully. Jumping to solutions without grasping the problem wastes time. Ask clarifying questions. Reproduce issues consistently. Gather data about when and how problems occur. This systematic approach leads to better solutions.
Breaking complex problems into smaller pieces makes them manageable. That overwhelming feature request becomes a series of achievable tasks. Each piece can be understood, implemented, and tested independently. This decomposition skill is fundamental to software development.
Analytical thinking helps you evaluate solutions objectively. Every approach has trade-offs. Quick fixes might create technical debt. Elegant solutions might take too long. Understanding these trade-offs helps you make informed decisions that balance immediate needs with long-term maintainability.
Learning from problems prevents their recurrence. When you fix a bug, understand why it happened. Was it a misunderstanding of an API? A missing edge case? Poor communication? Each problem teaches lessons that make you a stronger developer.
Communication and Collaboration
Writing code is just part of iOS development. Communicating effectively with your team multiplies your impact. Clear communication prevents misunderstandings, aligns efforts, and creates better products.
Technical communication requires translating complex concepts for different audiences. Explaining a technical decision to another developer differs from explaining it to a product manager. Adapting your message to your audience ensures understanding and buy-in.
Written communication skills matter more than ever in remote work environments. Clear commit messages, helpful code comments, and detailed pull request descriptions save time. Documentation that explains not just what but why helps future developers (including yourself) understand decisions.
Active listening improves collaboration significantly. When designers explain their vision, listen for the underlying goals, not just the surface requirements. When users report issues, listen for the real problem, not just the symptoms. This deeper understanding leads to better solutions.
Giving and receiving feedback gracefully is crucial. Code reviews should improve code and share knowledge, not bruise egos. Frame feedback constructively. Focus on the code, not the person. Accept feedback as a learning opportunity. This positive approach creates healthy team dynamics.
Attention to Detail
iOS users have high expectations. They notice misaligned text, inconsistent spacing, and janky animations. Attention to detail separates professional apps from amateur efforts. This skill extends beyond visual polish to code quality and user experience.
Visual details matter more than you might think. That one-pixel misalignment bugs users even if they can't articulate why. Consistent spacing creates visual rhythm. Smooth animations feel professional. These details add up to an impression of quality.
Code details affect maintainability and reliability. Consistent naming conventions make code readable. Proper error handling prevents crashes. Memory management prevents leaks. These invisible details determine whether your app delights or frustrates users.
Testing requires particular attention to detail. Edge cases hide bugs that surface later. Different device sizes reveal layout issues. Various iOS versions expose compatibility problems. Thorough testing catches these issues before users do.
Documentation details help your future self and teammates. That clever algorithm needs explanation. API quirks need warnings. Setup steps need precision. Good documentation anticipates questions and provides clear answers.
Adaptability and Continuous Learning
iOS development changes constantly. New iOS versions bring new features and deprecate old ones. Swift evolves with better ways to solve problems. Design trends shift user expectations. Adaptability keeps you relevant in this dynamic field.
Learning new technologies requires balancing depth with breadth. Deep knowledge of core technologies provides a strong foundation. Broad awareness of new developments helps you choose the right tools. This balance prevents both stagnation and constant tool-chasing.
Staying current requires intentional effort. Follow iOS developer blogs and podcasts. Attend conferences or watch session videos. Try new features in side projects. Join developer communities for discussions. These activities keep your skills sharp.
Embracing change rather than resisting it makes transitions smoother. When SwiftUI arrived, developers who embraced it early gained valuable experience. When async/await simplified concurrency, early adopters wrote cleaner code sooner. Seeing change as opportunity, not threat, accelerates growth.
Learning from mistakes accelerates improvement. Every bug teaches something about the system. Every rejected app store submission clarifies guidelines. Every user complaint highlights improvement opportunities. This growth mindset transforms setbacks into stepping stones.
Conclusion: Building a Strong Foundation for iOS Development
The iOS developer's toolkit in 2025 combines deep technical knowledge with essential soft skills. From mastering Swift and understanding legacy Objective-C to navigating complex frameworks and development tools, the technical requirements are substantial. But technical skills alone aren't enough.
Success requires understanding Apple's design philosophy and implementing it thoughtfully. It demands clear communication with team members and stakeholders. It needs problem-solving abilities that turn challenges into solutions. Most importantly, it requires adaptability in an ever-changing ecosystem.
When you hire iOS developers, look for this complete package. Strong candidates demonstrate proficiency across programming languages, frameworks, and tools. They show understanding of design principles and architectural patterns. They communicate clearly and collaborate effectively. They display curiosity and commitment to continuous learning.
The best iOS developers balance multiple skills effectively. They write clean, maintainable code while meeting deadlines. They implement designer visions while ensuring technical feasibility. They embrace new technologies while supporting existing codebases. This balance creates apps that delight users and succeed in the marketplace.
Building a strong foundation in iOS development is an ongoing journey. The landscape will continue evolving, bringing new challenges and opportunities. Developers who master both current tools and learning itself will thrive. They'll create the next generation of iOS apps that enrich users' lives.
Whether you're hiring iOS developers or developing these skills yourself, remember that excellence comes from continuous growth. The toolkit outlined here provides a roadmap, but the journey requires dedication, practice, and passion for creating great software. The iOS platform's future is bright, and skilled developers will shape it.
