Flutter - 无法在 Android Studio 上构建 iOS 应用程序

Question

I'm using Flutter with Android-Studio, everything was working great (ie compiling and deploying to iOS simulators except until I installed Fastlane Tools . The building process now is broken somehow! I'm not sure if it's from Fastlane or something else though, but now I'm stuck and cannot deploy to iOS anymore.

Steps taken/tried already:

1. Removing XCode & CommandLineTools (using this post: Complete removal old XCode )
2. Reinstalling XCode 9.2 (from AppStore)
3. Reinstalling CommandLineTools for XCode 9.2 (dl from developer tools page)

4. Reinstalling/updating ios-deply using:

   npm install -g ios-deploy --unsafe-perm=true

Any suggestions, please?

Answer 1

This answer is for the ones who are still trying to work with Xcode 9.2. Starting April, 2020, all apps submitted to the App Store will need to be built with Xcode 11. So don't try to build your Flutter IOS App with XCode 9.2. Flutter is also changing rapidly therefore, it is better to use the latest XCode version to avoid any deprecated API issue.
