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?

Kill all simulator processes

$ sudo killall -9 com.apple.CoreSimulator.CoreSimulatorService

Set the correct Xcode path

$ sudo xcode-select -s /Applications/Xcode.app/Contents/Developer

If that doesn’t work, reset all simulators

$ xcrun simctl erase all

First, try to close any running Simulator and Xcode instances. Then, restart CoreSimulatorService.

sudo killall -9 com.apple.CoreSimulator.CoreSimulatorService

You should now be able to build and run your app without any issues.

If not, another issue that you might encounter is that the Xcode upgrade deleted some versions of iOS. You might need to download an iOS Simulator from Xcode. I upgraded from Xcode 10.2, to 10.3, and no simulator was available.

Go to Xcode -> Preferences, and click on Components.

From there you will be able to download a version of iOS.

After the download is complete, close any running Simulator and Xcode instances again and try restarting CoreSimulatorService.

sudo killall -9 com.apple.CoreSimulator.CoreSimulatorService
