Answer 1

I had the same problem updating Xcode. Solve just logging back into Xcode.
Open Xcode
Open the project's Runner.xcworkspace file
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

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 5

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 6

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 7

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

Answer 8

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 9

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 10

I encountered the same error on flutter 2.5.3. Now I downgraded to 2.5.1 and the app is running on my iOS emulator. Try this may help you.

Answer 11

I have solved it by clean the IDEA + flutter clean then restarting Mac then open Xcode from flutter project then clean Xcode build by select product -> Celan Build folder then RUN your project from Xcode to download dependence

Answer 12

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 13

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

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