Answer 1

I had the same problem updating Xcode. Solve just logging back into Xcode.

1. Open Xcode
2. Open the project's Runner.xcworkspace file
3. Log into Xcode at: "Signing & Capabilities" -> "All" -> "Signing"

Item 3 was my problem. When updating Xcode, I was logged out.

Answer 2

Adding these lines to Podfile Helped me.

target.build_configurations.each do |build_configuration|
    build_configuration.build_settings['EXCLUDED_ARCHS[sdk=iphonesimulator*]'] = 'arm64 i386'
end

Example:

Answer 3

If you use package sign_in_with_apple, it should have 3.2.0 version at least.

Answer 4

The only solution that worked for me was to completely remove the xcode installed and reinstall from the app store.

When removing the old xcode, make sure to remove all the residual files - especially the developer folder. Try these following commands

sudo rm -rf ~/Library/Developer/
sudo rm -rf ~/Library/Caches/com.apple.dt.Xcode

and remove xcode from Application to bin. Doing this will completely clean the xcode residuals and then you can reinstall from the appstore.

Answer 5

put this code in your Podfile

post_install do |installer|
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)
    target.build_configurations.each do |build_configuration|
        build_configuration.build_settings['EXCLUDED_ARCHS[sdk=iphonesimulator*]'] = 'arm64 i386'
    end
  end
end

I encountered same issue and by running flutter clean fixed the issue for me.

Also try restarting the IDE if this doesn't work.
