Flutter App doesn't run on iOS Simulator, flutter build ios works-CodePudding

I am trying to run my flutter app, which uses firebase, in the iOS simulator on my Apple Silicon Mac, but it is not working. flutter run throws the following error, but flutter build ios works without error. Does anyone have a similar problem and can help me? I have already tried the following things (unfortunately without success):

Here is my terminal output (for flutter run):

flutter run

Try those steps;

cd ios

pod deintegrate

pod install

cd ..

flutter clean

flutter build ios

flutter run

If it's not work then share your ios/Runner/AppDelegate.swift file please

CodePudding user response：

Try running your Xcode first and make sure that it's up-to-date. Open the {flutter_project}/ios build on Xcode then try to run the iOS project on the Simulator from there.

If you're still having issues, you can run this command on your Terminal. This usually resolves issues running Flutter iOS builds on the simulator and should set the path for the active developer directory.

sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer
