I faced same issue when i merge code form git with other developer code. i tried many time to clean my project. But nothing help me out.

I open storyboard in source code. Start comparing with last working repositories storyboard. Then i found a same label appear two time in same screen. then i remove one of then and save. It helps me.

you can check your xib or storyboard.
