Helper to Backport Beta Platform Support

Tell us how we can improve Xcodes
Running on Beta Life (TM) can be harsh if you need to use a non-beta Xcode for some reason. Xcode is unable to work with a device running the betas because it doesn't have the device support.

What would you like to see? How would you like it to work?
There's been a trick for years that you can copy the platform support from the beta Xcode back into any previous version, and then magically you can use an old Xcode with a new beta. Some people also just symlink it. Example:

sudo ln -s /Applications/Xcode11.4.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/13.4 /Applications/Xcode11.1.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport

Not sure the UI/UX for this (prompt after installing a beta to copy into your current?), but it would be nice to be able to trigger this somehow, even possibly even have Xcodes manage the process entirely for us.

No source file, test, or entry point is named. Start by reviewing the existing Xcodes install and version-switching workflow, then clarify with maintainers whether the feature should copy or link beta DeviceSupport files and when it should be triggered. Done should include an agreed UI/UX and a defined way to use a non-beta Xcode with a beta device.
