Could not rename new group to Xcode?

You do this but looking to the left side of the folder(there is a triangle/arrow) if the triangle is pointing down, this means the folder is open and Xcode won't allow you to rename the folder. Simply press the triangle to close it (it will be pointing towards the right when closed) and try to rename again.

I was facing the same issue today. Only thing which helped me was quitting the Xcode and restarting it. It is working for me now
