There are two developers at the project, each of them has his own Apple developer account and there is no team account. After pulling changes from git, which contains change in .pbxproj file needs to change team back and it's quite annoying. xCode signing page
after team changing there is a high probability this change should push to origin and teammate will need to fix team too
I suspect that it can be fixed with .gitattributes file, but have no idea, how to do it.
