At my last company, there was 1 full time iOS engineer (me) and we later grew to about 18 full time iOS engineers. The xibs are painful point started happening around 8 full and part time iOS engineers.
You have many part time iOS engineers who may need to touch UI once in a while, and that can cause issues. After a dozen 'I have to throw away all of my xib work and recreate it because they've committed a new version of the xib', you become fine with just not using xibs any more.
Another annoying point is that Xcode tends to modify xib any time you open it. You don't need to do anything, just open it and boom, it gets that "M" in source control.
