[BUG] Swift Compiler Error on iOS devices #475

Closed juria closed 3 years ago

juria commented 3 years ago

Describe the bug After updating this package to version 8.0.0 it is not possible to compile my app on iOS devices.

To Reproduce Add dependency youtube_player_flutter: ^8.0.0 to pubspec.yaml and try to run your Flutter app on an iOS device. I used debug mode and tried on simulated devices and on a real device.

No problems on Android. Previously I already used youtube_player_flutter: ^7.0.0+7and had no problems on both platforms (iOS and Android).

Expected behavior The app should start and all functionality should be like on version 7.0.0+7 (but null-safe).

Technical Details:

Additional context Version 8.0.0 is necessary to migrate your Flutter app to full sound null-safety. That's why it is no possibility for me to use version 7.0.0+7 in the future.

(The original error logs are much longer, but all messages are similar and not clear to me.)

Probably the error happens because of the nested package flutter_inappwebview. I found a similar issue there: https://github.com/pichillilorenzo/flutter_inappwebview/issues/779

The solution there was to update XCode. I'll try this (next tuesday) and if it fixes my error, I will close this issue here.

Updating XCode to version 12.4 fixed the error.
