iOS UUID different for same app depending if installed through xcode or testflight

I'm finding that the UUID I get is different depending on whether the app is directly installed by xcode (which I do during development) or through testflight.

let uuidstring = UIDevice.current.identifierForVendor!.uuidString

Is it possible to get a UUID that is the same in both cases?

Ideally a UUID that is truly a unique device identifier, and doesn't change if the app is removed and added, which seems to change the UUID currently.

As the documentation says

The value in this property remains the same while the app (or another app from the same vendor) is installed on the iOS device. The value changes when the user deletes all of that vendor’s apps from the device and subsequently reinstalls one or more of them.

This is the reason why reinstalls will change the UUID for an App.
