when Xcode updated the last version 12.5 when I build IOS app it failed because of flutter and pods Cryptoswift
I tried to pod update but it downloads 0.15.0 not the last version of Cryptoswift
I ended up fixing flutter_pusher_client package to use most recent PusherSwift https://github.com/heywhy/flutter-pusher-client/pull/23
Until package is up to date you can use updated version
@pubspec.yaml
flutter_pusher_client:
git:
url: https://github.com/yfer/flutter-pusher-client.git
The problem was with flutter_pusher_client: ^0.3.1 and laravel_echo: the packages not updated and they use an old version of Cryptoswift and get failed in build.
