How to fix "Concurrency is only available in iOS 15.0.0 or newer" error Flutter – Ios swift

I recently updated my Flutter SDK to 3.0.4, and my project would no longer build when trying to launch on the iOS Simulator.

I got the following errors and implemented the solutions below each error:

The iOS Simulator deployment target 'IPHONEOS_DEPLOYMENT_TARGET' is set to 8.0, but the range of supported deployment target versions is 9.0 to 15.0.99.

Solution that has worked in the past but fails now since this is also included in the error message: Flutter – The iOS Simulator deployment target 'IPHONEOS_DEPLOYMENT_TARGET' is set to 7.0 && Build input file cannot be found GoogleService-Info.plist

and

error: 'Flutter/Flutter.h' file not found

Solution when I got above error, worked in the past, not now: error: 'Flutter/Flutter.h' file not found when flutter run on iOS (basically deleting and rebuilding ios folder)

I then tried to re-implement this (https://codewithandrea.com/tips/speed-up-cloud-firestore-xcode-builds/) after rebuilding the ios folder (requires a new podfile) in the solution above as the builds took forever to fail, and it worked well before the Flutter update. I used firestore version 9.2.0 since that is what was in my podfile.lock file.

This is when I started getting the swift compiler error I cannot solve, shown below. Other projects are running with the flutter update and on this simulator. Even after reversing the solution from the "code with Andrea" link above, I still get this same error.

pod install, pod update, flutter pub cache repair, flutter clean, flutter pub get, pod install –repo-update, none of these solve the error.

Please help.

    Turns out this issue was caused by XCode. Uninstalling and reinstalling the most recent version solved it for me


  2. 0

    previewIn you podfile. Check the platform version uncomment it and change it to 11. Also open the runner.xcworkspace in xcode. You will see warnings ontop. Click on those warnings and click on perform charges. And run the project from Xcode once

    EDIT

    If you click on the icon that’s marked in red. It should open the warning on the left pane. Select each one and it will show a pop up to resolve versions.

    Also execute pod install --repo-update and try once
