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.

Happened to me too, wasted almost an entire day scouting for possible causes.

The steps that finally fixed the problem and allowed me to install on simulator:

1. Quit Xcode and iOS Simulator
2. Remove /Library/Developer (the one from root), or rename it if you want to keep a backup
3. Relaunch Xcode, agree with the installation of command line tools
4. Continue work where you left over :)

Besides the steps mentioned in the question (fully uninstall Xcode 11, fully uninstall Xcode 10 and reinstall it afterwards), I also tried cloning the project in another location, circulating through all possible locations for derived data, installing other simulator runtimes and trying on those. None of them worked, luckily the console log app shown the path for the process that rejected the app bundle, it was one of the binaries installed by Xcode in /Library/Developer/PrivateFrameworks/CoreSimulator.framework.

Seems that Xcode 11 installed a newer version of the frameworks, and Xcode 10 was not overwriting them. Removing the whole /Library/Developer folder triggered the command line tools installation, which finally brought back the simulator runtime that properly worked in Xcode 10.

You gotta love the betas :)

I went to targets and found "Version" field is empty, just fill a number, for example 1.0
