Xcode Ver. 10.3 - Will not compile Chap. 31 Final App Version

📚 Official Books iOS Apprentice

When I attempt to compile Chapter 31 Final with the latest version of Xcode Version 10.3 (10G8) I get the following error:

“Source Code/31-Polishing the App/chapter-31-final/MyLocations/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”

The app runs fine under the previous version of Xcode (10.2).

Please advise.

It appears that none of my recent apps will compile under Xcode 10.3.

Hi @stevelhunt, sorry to hear about the issues you’re having with Xcode. Have you tried restarting your computer or cleaning the build folder in Xcode using Command+Option+Shift+K?

Best,
Gina

After downloading the latest beta version of MacOS Catalina and cleaning my app folders, my system seems to be working properly again. Thanks for the advice.
