Cannot run application on simulator after installing Xcode 11 - CFBundleVersion error

Question

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:

Failed to install the requested application
Domain: NSPOSIXErrorDomain
Code: 22
Failure Reason: The application's CFBundleVersion is invalid.
Recovery Suggestion: Ensure your bundle contains a CFBundleVersion with a valid semantic version number.

I've closed beta version and tried to run again with latest stable version of Xcode (10.2.1), but the same error has occurred. I need to mention that before attempting to run a project with Xocde 11, it worked without any problems on Xcode 10. Nothing has been changed before and after running with beta Xcode.

What I've already tried:

• I've removed Xcode 11 beta
• I've cleaned my project and pulled it from latest branch
• I've completely removed Xcode 10 from:

~/Library/Caches/com.apple.dt.Xcode
~/Library/Developer
~/Library/MobileDevice
~/Library/Preferences/com.apple.dt.Xcode.plist
/Library/Preferences/com.apple.dt.Xcode.plist
/System/Library/Receipts/com.apple.pkg.XcodeExtensionSupport.bom
/System/Library/Receipts/com.apple.pkg.XcodeExtensionSupport.plist
/System/Library/Receipts/com.apple.pkg.XcodeSystemResources.bom
/System/Library/Receipts/com.apple.pkg.XcodeSystemResources.plist

• And then installed fresh stable version 10.2.1

I can run other projects which was not tested with Xcode 11 without any problems.

My last idea is to just reinstall macOS, but I would like to don't do it.

Edit: I’ve forgot to mention that application is working on physical iPhone XS.

Answer 1

There is a lot of misinformation in the answers here, so I wanted to provide an authoritative response.

The issue here is that the new version of CoreSimulator.framework with Xcode 11 beta does validation on CFBundleVersion that previous versions did not do. These checks are valid, and it does represent an issue in your application, but there's also a bug in how the checks were performed in Xcode 11 Beta 1 which compounds the issue.

First, fix the CFBundleVersion in your Info.plist. It should consist of only numbers and up to two periods (ie ##.[.##[.##]], eg: 12.4.2).

Second, after fixing CFBundleVersion, you need to killall -9 CoreSimulatorBridge because the old value is unfortunately cached in CoreSimulatorBridge, preventing it from recognizing the new value. This part was a bug, and it was addressed in Xcode 11 Beta 2.
