This seems pretty obvious now that I know it but my Google fu failed me on this one, so I thought I’ll add a note about it should someone encounterthis issue. I was working with the TableViewController and my app would crash with this error:

I’m using a StoryBoard and the issue is that I had more than one prototype cell visible in the table view. The error says that there is more than 1 cell with the same Identifier:
The solution is to set the number of Prototype Cells to the actual number of different types of cells you have (the ‘type’ being identified by the ‘identifier’). In my case, I just had 1 type of cell and so I set the number of Prototype Cells to 1.
