I just upgraded my Flutter version to 1.22.0. After upgrading and making some changes for Firebase my Android app started working, but I am unable to build and run the iOS app on emulator or on physical device.

The terminal shows the following errors when I try to run the app in the emulator or physical device. The emulator runs on iOS 14 and the physical device is on 14.0.1.

Emulator: ld: symbol(s) not found for architecture x86_64 Actual device: ld: symbol(s) not found for architecture arm64

I also executed the following commands but still not working...

flutter clean && \ rm ios/Podfile ios/Podfile.lock pubspec.lock && \ rm -rf ios/Pods ios/Runner.xcworkspace && \ flutter run

It looks like this problem is coming due to RevenueCat API. When I comment out the import purchases_flutter in the pubspec.yaml file then I am able to install the app but it crashes at startup saying connection lost.

  • Could you show your flutter doctor, and pubspec.yaml file content? Commented Oct 6, 2020 at 19:05
  • Might also help this: rm -f ios/Runner.xcworkspace/xcshareddata/WorkspaceSettings.xcsettings github.com/flutter/flutter/issues/51992#issuecomment-596865108 Commented Oct 6, 2020 at 19:07
  • Thanks for your reply, I tried that but it is giving same error after that.... Commented Oct 6, 2020 at 19:31

rm -f ios/Runner.xcworkspace/xcshareddata/WorkspaceSettings.xcsettings fixed the issue for me

When I go to ios/Runner.xcworkspace/xcshareddata there is no WorkspaceSettings.xcsettings file. There is only one file available which is IDEWorkspaceChecks.plist

There are a couple of different answers for this here on stackoverflow. If I am not mistaken, the switch to channel "stable" solved the issue for me, last time.

I thought to switch the channel too but then I realized I'm already on the stable channel.
I guess, you have already rebooted. This also still sometimes helps to fix (non) errors. Could this be caused by keyWindow, whatever that is? Have you tried some other app without keyWindow, whether that runs?
right now I am ignoring these issues as they are only warnings

I also having problems after I upgrade to 1.22.0, I had to also upgrade the flutterFire package, and that seems to be my problem.

the versions that I'm using on pubspec.yaml: 

 firebase_core: ^0.5.0 cloud_firestore: ^0.14.1+2 firebase_auth: ^0.18.1+1 firebase_analytics: ^5.0.0 cloud_functions: ^0.6.0+1 firebase_storage: ^4.0.1 firebase_crashlytics: ^0.1.0+3 firebase_messaging: ^7.0.2

when trying to run it says to update the CocoaPods spec by running pod repo update, done that, but still got the same error, then running pod install or pod update got the error enter image description here

tried the commands: pod install --repo-update and pod update Firebase/Storage but still got the same error message

Yes, the solutions for me was to deleted the podfile.lock, run flutter clean and run the app.
I am glad it worked for you. For me it is still not working.. :-(
not sure if your problem is with the flutterFire, but later I found this migration guide firebase.flutter.dev/docs/migration

Just remove old flutter installed folder like [.cache] / [pub-cache] because you might have upgraded the flutter version but iOStools and other tools are pointing to older version and it causes these architecture issue.

Are you sure about this?

Finally after doing lot of changes, I found out that the culprit was the purchases_flutter: ^1.3.1 package.

When I remove the package from my yaml file then it starts working. There is a bug already opened for it https://github.com/RevenueCat/purchases-flutter/issues/120.

Thank you every one for your time and help.
