Describe the bug After updating to the newest nativescript and @nativescript/ios, tns run ios is not working anymore. I get the following error:

** BUILD FAILED **

Unable to apply changes on device: 31FE16F7-4244-4521-AF2F-BFAF9020FC98. Error is: Command xcodebuild failed with exit code 65.

I tried to fix this as suggested in this post: https://github.com/NativeScript/nativescript-cli/issues/4035

In the List of Frameworks, Libraries and Embedded Content I found TNSWidgets.xcframework and TNSWidgets.framework. After deleting one of them (no matter which one) and running tns run ios again, I get another error:

Unable to apply changes on device: 31FE16F7-4244-4521-AF2F-BFAF9020FC98. Error is: Command xcrun with arguments simctl install 31FE16F7-4244-4521-AF2F-BFAF9020FC98 /Users/anoki/Downloads/sepm/ss20_sepm_qse_14/frontend_nativescript/platforms/ios/build/Debug-iphonesimulator/frontendnativescript.app failed with exit code 22. Error output:
 An error was encountered processing the command (domain=NSPOSIXErrorDomain, code=22):
Failed to install the requested application
The bundle identifier of the application could not be determined.
Ensure that the application's Info.plist contains a value for CFBundleIdentifier.

All posts I found regarding this error suggest cleaning the project, which results in the first error again.
