Couldn’t open xib file after git pull, invalid element name

Glad you corrected the issue. I recently ran into the same issue. It a merge conflict and that is why Xcode is throwing that error. Within the .xib file you will see something like:

<<<<<<< HEAD

// code

=======

// code

>>>>>>> apps

You can do what you did above, or manually correct the merge conflict issues by opening the .xib file in XCode(In XCode, right click on the storyboard/xib file -> Select 'Open As' -> Source Code) or in a text editor. After correcting it the file should open fine in Xcode.
