🐛 [Firebase Firestore] swift Force Load _swiftCompatabilityConcurancy

[waleedkalyar]

Hi sir, I have implemented flutter fire inside my flutter project. For reducing time I have added build in C++ libs in Pod file as flutter fire documentation says. But whenever I try to build its give me the error of

Undefined symbol: _swift_FORCE_LOAD$_swiftCompatabilityConcurancy

I am unable to figure out the problem.
Btw it will build if I remove
pod 'FirebaseFirestore', :git => 'https://github.com/invertase/firestore-ios-sdk-frameworks.git', :tag => '9.4.0'
from my Pod file. But It will take almost one hour on my MacBook to build.

My OS is -> Mac OS big sure version 11.5.2
My Xcode version is -> 13.0.0
Its become pain in my head to use firebase Firestore. If I remove Firestore dependency build work like charm.
Please help me to sort this problem.

Can you provide flutter doctor -v, complete error log along with pubspec.yaml and ios/podfile in properly formatted text.

If you change to 9.3.0 and try, do you get same error ?
Also, can you try to delete podfile.lock, run flutter clean followed by pod repo update and see if it helps ?

[waleedkalyar]

I have tried with both 9.3.0 and 9.2.0 delete podfile.lock And already done all these steps.
But still the issue is:
Error (Xcode): Undefined symbol: __swift_FORCE_LOAD_$_swiftCompatibilityConcurrency
