I did what @bigbubble suggested and it worked for me. I am currently restricted to using Xcode 10.3 due to limitations outside of my control in the enterprise. My iPad automatically updated to iOS 13.3 so I needed iOS 13.3 support in Xcode 10.3. So I copied /Applications/Xcode11.3.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/13.2 to /Applications/Xcode10.3.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/13.3 and all worked well.
