How to disable Interface Builder document versioning from auto updating?

Question

This question is still getting a lot of upvotes. So look at Update3. once you have upvoted, commented, answered, please please please file a radar

Answer 1

Version 4.6.3 of Xcode resolves this issue. However, as the comments state, you all need to be running that same version. If four developers are on 4.6.3, and one is on a previous version, then that developer will experience the same issue. However, if they do not commit that change then it will not affect the others.

The two Xib keys affected are:

1187.39
12E55

So, bottom line, get everyone on the team to update to Xcode 4.6.3.
