| # The trick is to link the DeviceSupport folder from the beta to the stable version. | |
| # sudo needed if you run the Mac App Store version. Always download the dmg instead... you'll thank me later :) | |
| # Support iOS 15 devices (Xcode 13.0) with Xcode 12.5: | |
| sudo ln -s /Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/15.0 /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 | |
| # (A similar approach works for older versions too, just change the version number after DeviceSupport) |
