[SOLVED] 'This app could not be installed at this time' error Xcode

'This app could not be installed at this time' error Xcode

When I am trying to run my Flutter app, the build is succeeded, but when xcode tries to install this build automatically on the simulator, the following error occurs:

The parent bundle has the same identifier
     (com.abc.def) as sub-bundle at 
    /Users/jan/Library/Developer/CoreSimulator/Devices/DFF35FBB-FE6C-462E-80964BFBFAF57291/data/Library/Caches/com.apple.mobile.installd.staging/temp.zyu9i6/extracted/Runner.app/Frameworks/App.framework

I am already stuck for a couple of days with this error. I don't find an answer for this issue on the word wide web.

I already tried to erase all content and settings of the simulator, but that does not solve the problem. Cleaning the project is also not the solution.

Thanks!

Solution

You need to change the CFBundleIdentifier in this file :

ios/Flutter/AppFrameworkInfo.plist

Add ".app" to the flutter BundleId "XXX" :

<key>CFBundleIdentifier</key> <string>XXX.app</string>

With "XXX" your own bundle-id.
