predictabilize_uuids doesn't work as expected #1009
Description
Appreciate the awesome work you've done here!
We are using Xcodeproj in our Podfile ruby script to basically build up our Xcode project targets from scratch, because we whitelabel our app. On each install, we delete all targets, then we recreate them based on our own configuration list. We use project.predictabilize_uuids, however it gives a multitude of warnings of duplicated UUIDs (seems to have no impact aside from the warning), and even so, the UUIDs are not predicable, they all change on the next install regardless.
Can you give some pointers as to why the UUIDs are not stable? The entire project configuration itself is stable - most of it is deleted and recreated each time but the resulting content is stable aside from the UUIDs.
