I already have a fully-functioning Flutter application live on Android. I now need it running smoothly on iOS and available in the Apple App Store as soon as possible. Here is what I’m looking for: • Open the existing Flutter codebase in Xcode, resolve any iOS-specific dependencies, and confirm the app launches and behaves correctly on an iOS simulator and a real device. • Generate a clean iOS build ready for TestFlight. • Handle the missing pieces of my signing setup—some certificates and provisioning profiles are ready, but a few still need to be created or linked. • Work within the limited access I will grant to my Apple Developer account to upload the build, configure the App Store listing, and submit for review. • Provide concise hand-off notes so I can replicate the process for future updates. Speed matters: I’d like the build live in TestFlight and moving toward review ASAP. If you’ve shipped Flutter apps to the App Store before and can guide me through any inevitable Apple quirks, let’s get started right away.
