Using iOS 15 devices with Xcode 12.5 (instead of Xcode 13)

ios-xcode-device-support.sh

# 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)

If you need iOS 15.1 support (Xcode 13.1 has only 15.0 directory) you can also do this as a follow up to the original gist:

sudo ln -s 15.0 /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/15.1

which works at the time of writing (Xcode 13.1 and Xcode 12.5.1).

If you need iOS 16 support on Xcode 13.4.1, here's the command (make sure you've Developer Mode enabled):

sudo ln -s /Applications/Xcode\ 14\ Beta.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/16.0 /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport

I saw something in a build log (from Xcode 14) about CoreDevice being disabled, took a guess and if you do:

defaults write com.apple.dt.Xcode DVTEnableCoreDevice enabled

Then restart Xcode the iOS 17 device will show up in Xcode like this. Then you can run and debug the app as usual. I have Xcode 15 installed alongside Xcode 14 but not sure if thats a requirement. It took a while to copy symbols from device but eventually it got there.
