Yesterday, I\'ve downloaded beta version of Xcode 11. After that, I\'ve opened my project and tried to run with new Xcode. Unfortunately error has occurred with message:
In my case, the Build Version field was empty. I added the value there but still it didn't work. I tried killall -9 CoreSimulatorBridge command and that also didn't help.
Finally when I checked the xml of the info.plist (Open as -> Source code), the CFBundleVersion key was not present and the version was displayed in the info.plist through CFBundleShortVersionString.
I just added the CFBundleVersion key as given below in the info.plist and it worked.
I hope it helps someone else too.
