Runner.xcworkspace 이걸로 xcode를 실행해야합니다. 절대 Runner.xcodeproj 로 안됨

오류 :

bitcode bundle could not be generated because '/Users/jichangjung/Desktop/work/musubiya-flutter/ios/Flutter/Flutter.framework/Flutter' was built without full bitcode

해결방법:

You should run flutter build ios in your flutter project directory before archiving.
