iOS app development for iPhone and iPad

Several of Apple's rules affect screens and backend design, not just the final submission. It is far cheaper to plan for them in scoping than to discover them in a rejection email:

• Digital goods and subscriptions sold inside the app generally have to use Apple's in-app purchase. Physical goods and real-world services can use other payment providers.
• If users can create an account in the app, they must also be able to delete it from inside the app.
• Apps that offer third-party social login may need to offer Sign in with Apple or an equivalent privacy-focused option.
• Tracking users across other companies' apps and websites requires Apple's App Tracking Transparency prompt.
• Every permission, such as camera, location or contacts, needs a clear explanation of why the app asks for it.

The app is published under your own Apple Developer Program membership, which Apple charges for annually. I set up the build pipeline, create the App Store Connect record with you and send builds to TestFlight, where you and your team install them on your own iPhones. Inviting outside testers through TestFlight also needs a short beta review from Apple.

For the final submission I prepare the privacy details, screenshots, review notes and, where the app has a login, a demo account for Apple's reviewer. If the app is rejected, I fix and resubmit it at no extra cost. Approval itself is Apple's decision and cannot be guaranteed.

An iPhone app can still be installed on an iPad, where it runs in a compatibility mode, so it has to behave properly there even if iPad is not a target. A dedicated iPad layout is a separate design job: larger screens usually suit split views, side panels and denser tables. Decide early whether iPad matters to your users, because it changes the number of screens in scope.

Flutter apps for iOS are compiled with Apple's own toolchain and reach device features such as the camera, notifications and biometrics through plugins. Where a feature needs native code, a small amount of Swift sits alongside the Flutter app. The benefit is that your Android app shares the same codebase, design and fixes.
