Running app for iOS, renaming its root folder and trying to run it again - build fails after renaming project root folder with this error:

xcodebuild: error: '/Volumes/NHRISTOVA/Work/NS/AppRen2/platforms/ios/AppRen2.xcodeproj' does not exist.
Unable to apply changes on device: F6900C39-7AAA-45C8-AFF6-D923DBEF1E8E. Error is: Command xcodebuild failed with exit code 66.

NOTE: iOS build is successful after removing iOS platform. However, this works for android without removing android platform.

Please provide the following version numbers that your issue occurs with:

• CLI: 4.0.0
• Runtime(s):

Is there code involved? If so, please share the minimal amount of code needed to recreate the problem.

Consider using the playground to provide the code you have issues with.

Reproduce the sequence with tns create, tns run ios, a root-folder rename, and a second tns run ios. Start with the iOS build path that assembles the logged xcodebuild -project command and inspect how it derives platforms/ios/AppRen2.xcodeproj. Done means the renamed project builds without removing the iOS platform, while the existing Android behavior remains intact.
