I’ve been using the iOS Apprentice Book (6th Ed) and just started with the Checklists portion. When I added the code on page 192, and run the program, it crashes. As soon as I comment out the code, it runs fine. I have double-checked what I typed in and its correct. I just upgraded to xCode 10 - if that makes a difference?
Error message in code:
class AppDelegate: UIResponder, UIApplicationDelegate { Thread 1: signal SIGABRT
Error in Debug:
Checklists *** Assersion failure in - [UITableView_dequeueReusableCellWithIdentifier:forIndexPath:usingPresentationValues:]
Checklists *** Terminating app due to uncaught exception ‘NSInternalInconsistencyException’, reason ‘unable to dequeue a cell with identifier ChecklistItem - must register a nib or a class for the identifier or connect a prototype cell in a storyboard’
Did you set the reuse identifier as per page 197? It looks very much as if you didn’t set the reuse identifier or might have made a spelling mistake in specifying the identifier …
Unfortunately, I have not gotten that far yet. I stopped when I received the error. I will look it over again this evening and I will also see what you referenced on page 197. Thanks!
Since there is no code on page 192 (at least on my PDF copy), I was confused by your original comment about adding the code from page 192. The first bit of code I see after page 192 is on page 198 under the title “The table view delegates”. So there’s something wrong here but I can’t say what is going on without knowing the actual page numbers
YES! That’s it…when I added that code, I got the error. I just recreated the package up to that point and it runs just fine. Apparently I did something wrong the first time although I could not find it. One of those weird programming things…sorry, but thanks for your time just the same!
