This doesn’t look like it’s related to beacons. There’s a call to tableView:numberOfRowsInSection: method on a non-existing object. Maybe you’re calling reloadData on a UITableView whose delegate (in this case, it seems like it’s the ViewController itself) no longer exists.

Thanks for your input.
What i discovered was After downloading onto phone one of my students started to play around with the coding.
I rebuild and it works fine.
