iOS App Development Process

1. Initial Consultation & Requirement Gathering

• Understand the client’s vision, business goals, and target audience.

• Define app features, technical requirements, and platform considerations.

2. Scope & Proposal

• Outline project deliverables, timeline, and cost estimates.

• Define milestones and success criteria.

3. UI/UX Design & Wireframing (if applicable)

• Create wireframes and prototypes for app flow.

• Design a visually appealing and user-friendly interface following Apple’s Human Interface Guidelines.

4. Architecture & Tech Stack Planning

• Choose between SwiftUI or UIKit based on project needs.

• Define database structure, API endpoints, and third-party services.

5. Development (Agile Iterations)

• Implement core features and backend integration.

• Develop authentication, data storage, and essential functionalities.

• Ensure smooth UI interactions with Apple’s best practices for performance.

6. Testing & Debugging

• Conduct unit tests, UI tests, and manual testing across multiple devices.

• Identify and fix bugs, optimize memory usage, and ensure smooth performance.

7. Client Review & Feedback

• Provide a TestFlight build for client review and feedback.

• Implement requested revisions and enhancements.

8. Deployment & App Store Submission

• Prepare the app for App Store submission, ensuring compliance with Apple’s review guidelines.

FAQs

1. What services do you offer as a mobile app developer?
I specialize in Android (Kotlin/Jetpack Compose) and iOS (SwiftUI/UIKit) app development, providing end-to-end services from planning and design to development, testing, and deployment. I also offer backend integration, API development, Bluetooth connectivity, push notifications, Firebase services, and cloud hosting solutions.
2. Do you handle both iOS and Android development?
Yes, I develop native apps for both Android (Kotlin) and iOS (SwiftUI/UIKit). I also work with React Native for cross-platform projects when needed.
3. Can you help publish the app on the Google Play Store and Apple App Store?
I assist with and complete the entire deployment process, ensuring your app meets Google Play and Apple App Store guidelines and handling metadata, screenshots, and compliance checks.
4. What’s your typical process for developing an app?
I follow a structured process: 1. Requirement Gathering & Planning 2. UI/UX Design (if needed) 3. Development (Agile Iterations) 4. Testing & Debugging 5. Client Review & Refinements 6. Deployment & Store Submission 7. Post-Launch Support & Maintenance
5. How long does it take to develop an app?
Timelines vary based on complexity. Simple apps may take 2-4 weeks, while complex apps with APIs, real-time features, or Bluetooth integration may take 2-3 months or more.
6. How much does an app development project cost?
I charge an hourly rate of $150/hr, and project estimates are based on the scope and complexity. After an initial consultation, I can provide fixed-cost estimates for larger projects.
7. Do you offer post-launch support and maintenance?
Yes, I offer ongoing support, updates, bug fixes, and feature enhancements to keep your app running smoothly after launch.
8. Can you integrate third-party services like Stripe, Firebase, or Bluetooth devices?
Absolutely! I have experience integrating payment gateways (Stripe, Apple Pay), Firebase services, Bluetooth LE devices, APIs, and various cloud platforms (AWS, GCP, Firebase, Supabase).
9. Can you work with an existing codebase?
Yes, I can refactor, debug, optimize, or extend existing iOS or Android codebases.
10. Why should I work with you?
I bring years of hands-on experience, a focus on clean and scalable code, and a deep understanding of native mobile development best practices. I don’t just build apps—I ensure they are efficient, user-friendly, and future-proof.
