title: Xcode 10.3 Installation
body: <p>I have just been (involuntarily) upgraded to Xcode 10.3 (10G8). I'm getting the following error:</p>
  
  <blockquote>
    <p>/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</p>
  </blockquote>
  
  <p>It appears that the upgrade to Xcode is incomplete.</p>
  
  <p>How do I ensure a complete installation, if this is the problem?</p>
