need to produce an archive so we can upload to TestFlight so followed instructions in https://flutter.dev/docs/deployment/ios . my flutter runs on both real iPhone and simulator with no problem. so I produce a release version as required then open the resultant Xcode project (runner). immediately see the error

:-1: Multiple commands produce '/Users/jmcfet/Library/Developer/Xcode/DerivedData/Runner-cwxykfeiijpirmgbtrkzktdrahbt/ArchiveIntermediates/Runner/InstallationBuildProductsLocation/Applications/Runner.app/Frameworks/Flutter.framework': 1) Target 'Runner' has copy command from '/Users/jmcfet/AndroidStudioProjects/sis/ios/Flutter/Flutter.framework' to '/Users/jmcfet/Library/Developer/Xcode/DerivedData/Runner-cwxykfeiijpirmgbtrkzktdrahbt/ArchiveIntermediates/Runner/InstallationBuildProductsLocation/Applications/Runner.app/Frameworks/Flutter.framework' 2) That command depends on command in Target 'Runner': script phase “[CP] Embed Pods Frameworks”

now this does not happen when I do the same against the "Flutter Hello world" app so wondering what is messed up in my Flutter app

  • This seems to be a pod issue. First run pod install in your ios folder then run again flutter build ios --no-codesign then you can create the archive from Xcode. Commented Jul 5, 2019 at 21:01

no luck :

johns-MacBook-Air:ios jmcfet$ pod install Analyzing dependencies Fetching podspec for Flutter from .symlinks/flutter/ios Fetching podspec for video_player from .symlinks/plugins/video_player/ios Downloading dependencies Using Flutter (1.0.0) Using video_player (0.0.1) Generating Pods project Integrating client project Pod installation complete! There are 2 dependencies from the Podfile and 2 total pods installed.

[!] Automatically assigning platform ios with version 8.0 on target Runner because no platform was specified. Please specify a platform for this target in your Podfile. See https://guides.cocoapods.org/syntax/podfile.html#platform.

[!] CocoaPods did not set the base configuration of your project because your project already has a custom config set. In order for CocoaPods integration to work at all, please either set the base configurations of the target Runner to Pods/Target Support Files/Pods-Runner/Pods-Runner.profile.xcconfig or include the Pods/Target Support Files/Pods-Runner/Pods-Runner.profile.xcconfig in your build configuration (Flutter/Release.xcconfig).

not an IOS expert but looks like the install was not successful. little confused as the Xcode project was generated by Flutter so why is Flutter generating a bad config file. if so looks like a bug to me
