// The trick is to link the DeviceSupport folder from the beta to the stable version.

// Updated on Feb 15th, 2019 for Xcode 10.1

sudo ln -s /Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/12.2\ \(16E5191d\) /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport

// Then restart Xcode and reconnect your devices. You will need to do that for every beta of future iOS versions

// sudo needed if you run the Mac App Store version. Always download the dmg instead... you'll thank me later :)
