App was working fine then followed the video on Adding checkmarks when the table view is loaded and now all I get is that I click on the friends page and the app crashes. Any suggestions as to what has happened and how to fix it.

You might want to add an exception breakpoint to figure out where in your code the app is crashing. To learn how to add an exception breakpoint check out the Debugging Basics video.

I have added the exception breakpoint, and followed it though. It boiled down to

***Assertion failure in - [UITableView _configueCellForDispay:forIndexPath:], /SourceCache/UIKit_Sim/UIKit-2903.23/UITableview.m:6246.

Could you shed any light on what this actually means?

Thanks for you help Amit, I think I've resolved it would be easier to revert and redo.
