This article is for you who are still in Flutter’s stable branch (Channel stable, v1.12.13 + hotfix.9 or smaller) or when building an App you get the following error:
Building for iOS, but the linked and embedded framework ‘App.framework’ was built for iOS Simulator.
Or:
Building for iOS Simulator, but the linked and embedded framework ‘App.framework’ was built for iOS.
To fix the above error, you follow my instructions step by step below:
- Open the ios / Runner.xcworkspace file in your Flutter project
- You look over the Navigation Pane of XCode, inside the Flutter folder you will see App.framework and Flutter.framework .
- Gently remove them by Select -> right mouse -> Delete.
After removing, select Target Runner -> Build Phases> Link Binary With Libraries and Embed Frameworks to ensure that there are no more App.framework and Flutter.framework files.
Still in that build Phases , select Thin Binary and add the following script:
1 2 3 | /bin/sh "$FLUTTER_ROOT/packages/flutter_tools/bin/xcode_backend.sh" embed /bin/sh "$FLUTTER_ROOT/packages/flutter_tools/bin/xcode_backend.sh" thin |
And finally, you select Target Runner -> Other Linker Flags , add the following lines if not $ (inherited) -framework Flutter
Finally, if you still do not understand the components in XCode, I will give you a picture of all the components in XCode that we often use without paying attention.
Note : Flutter v1.15.3 and later versions have automatically migrated to your XCode project.
