BTW same thing happened on Big Sur so it's not about Monterey version.

Moreover, here's our

Podfile

$minVersion = '11.0'

platform :ios, $minVersion

  unless File.exist?(generated_xcode_build_settings_path)
    raise "#{generated_xcode_build_settings_path} must exist. If you're running pod install manually, make sure flutter pub get is executed first"
  end

  File.foreach(generated_xcode_build_settings_path) do |line|
    matches = line.match(/FLUTTER_ROOT\=(.*)/)
    return matches[1].strip if matches
  end
  raise "FLUTTER_ROOT not found in #{generated_xcode_build_settings_path}. Try deleting Generated.xcconfig, then run flutter pub get"
end

Emulator builds not working on iOS
It was working until it just stopped working. Build still work for an actual device.

@ljmatan I am not sure what you meant by this, Can you please edit the description of the issue and add some more details describing the issue, with reproducible steps (if known) and share the complete output of flutter run -v.

Thanks

@maheshmnj

Please see logs attached in the original post.

Flutter builds are working on an actual / physical iOS device but not on an iOS emulator.

[maheshj01]

@ljmatan I did check at those logs but I believe those logs are incomplete. So please run

flutter run -v > log.txt

and please share the log file generated in the root of the project.

Thanks

@maheshmnj these should be good thanks.

@ljmatan thanks for the logs, From the logs I could see these warnings,

           /Users/threeofthem/Projects/clickapo/ios/Pods/Pods.xcodeproj: warning: The iOS Simulator deployment target 'IPHONEOS_DEPLOYMENT_TARGET' is set to 8.0, but the range of supported deployment target versions is 9.0 to 15.0.99. (in target 'PINOperation' from project 'Pods')

even though you have forced the deployment target to 11.0 in the podfile

config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = $minVersion

can you please try running

flutter clean
flutter pub get 
flutter run

and share the output.

Thanks
