Plan

Have you tried building on a physical device? Or a different emulator version? What Xcode version is it using? – Hotspur

Is this after updating to Xcode 13? I'm getting the same thing and the main change I made is updating Xcode, I'm pretty sure. – Venita

Same here, have you found any solution ? – Beep

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:

Don't know why I suddenly started getting this error but this solution worked! Thanks – Radiolucent

This helped fix my issue as well! Thanks – Boomerang

Answer 3

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 4

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

As it’s currently written, your answer is unclear. Please edit to add additional details that will help others understand how this addresses the question asked. You can find more information on how to write good answers in the help center. – Bimestrial

This solution helped me too. But maybe just removing cache about sign_in_with_apple packge and let flutter pub and cocoapods gets it again would be a solution too. Note that, i didn't try it. – Demilitarize

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

Answer 6

For me, I am fine after forcing the Simulator.app quit and run the command again.

Answer 7

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

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

Answer 8

All of the answers here, depending on your circumstances, have aspects that absolutely remove this error. For myself, what I can say is that I can confirm that using an 2021 M1 macbook pro max with a fresh set of tools, flutter 2.8.1, dart 1.15.1 and having the following or similar post_install section in my podfile also silenced the offending output.

post_install do |installer|
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)
    target.build_configurations.each do |config|
      config.build_settings['DEBUG_INFORMATION_FORMAT'] = 'dwarf'
      config.build_settings.delete 'IPHONEOS_DEPLOYMENT_TARGET'
      config.build_settings['ONLY_ACTIVE_ARCH'] = 'YES'
      config.build_settings['EXCLUDED_ARCHS[sdk=iphonesimulator*]'] = 'arm64 i386'
    end
  end
end

I faced the same issue for flutter version 2.5.1 stable Previously i installed flutter using Zip archive file now I completely removed that installation and setup it using Git clone

I did things like flutter clean, pod clear cache , pod install etc IMP Note in xcode please check developer signing&capabilities options for runner etc I did these and these are worked for me

Answer 10

The relevant part here is

Command PhaseScriptExecution failed with a nonzero exit code

which means that any of the scripts configured in Xcode > Targets > Runner > (Tab) Build Phases failed. The problem here is that you do not see the error message (which script failed and why).

Add the --verbose flag (short: -v) to the flutter run command:

flutter run -v

This will output a lot. At the end you need to scroll a bit up to the the actual script error.

Once you know the actual error, you probably can solve it easily or open a new and more specific question.

Answer 13

Add the below lines to your podfile. Place the below lines in the post_install do [installer] section at the bottom of the Podfile.

Code :

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

Answer 14

Try this. This process will re-download ios and android development tools again after running the code through the ios and android simulator. Worked for me

Flutter clean

Flutter get

Flutter channel stable

flutter upgrade

and restart IDE as well as close Xcode. works for me, I hope this helps

Answer 15

If your project is with firebase and it is cloned and cleaning is not well like me. Probably this can help you.

1. Add GoogleService-Info.plist back to your Runner project. (if already have can ignore)
2. Try to Clean Build Folder on xcode then Build again.
3. Try to build into Simulator using xcode.
4. Try to build into your connected iPhone.
5. If 3 and 4 is working. Back to your vscode then build and run again to iPhone or Simulator
