Flutter iOS build failed after Flutter 1.22 upgrade

Question

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

Could not build the precompiled application for the device.

Error launching application on physical’s iPhone.

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.

Answer 1

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.

Answer 2

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.

Answer 3

I have a similar erro ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation) note: Using new build system note: Building targets in parallel note: Planning build note: Constructing build description

Answer 4

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

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

Answer 5

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

Answer 6

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.
