I have just been (involuntarily) upgraded to Xcode 10.3 (10G8). I'm getting the following error:
/Users/hgm/XCode/Gnosys/TGuide/TGPrep/Assets.xcassets:-1: Failed to find a suitable device for the type IBSimDeviceTypeiPad2x (com.apple.dt.Xcode.IBSimDeviceType.iPad-2x) with runtime iOS 12.4 (12.4 - 16G73) - com.apple.CoreSimulator.SimRuntime.iOS-12-4
It appears that the upgrade to Xcode is incomplete.
How do I ensure a complete installation, if this is the problem?
Download the latest version of Xcode from the Apple developer website or get it using the Mac App Store. Once you have Xcode installed, open a terminal, run xcode-select --install , and click the Install button to install the required command line developer tools.
The latest version of Xcode you can run on Catalina (10.15. 4) is Xcode 12.4 and Command Line Tools 12.4.
Restarting your computer/macOS will resolve the issue.
