What to do if you accidentally remove the reference to a file in Xcode?

Question

In the middle of coding an app, I wanted to delete a button. What I did not realize was that I was actually selected main.storyboard. When I pressed backspace to delete main.storyboard I pressed "Remove reference". At this point I tried command + z, but ,unfortunately, main.storyboard did not come back.I tried to run the app but I kept getting signal SIGABRT.

My question here is if you accidentally remove the reference to a file is there any way of recovering it?

Answer 1

Only "Remove reference", the file is disappearing only from Xcode and remaining in your real folder. Try to add Main.storyboard again from Xcode file navigator like this.
