When setting up the sign up page error messages for users signing up on Ribbit and trying to run the app it's crashing with the following error message and I'm struggling to find a solution.
Any help would be greatly appreciated.

Treehouse TeacherWithin that dense error message is a clue:
reason: '-[UITableViewController loadView] loaded the "Sgk-h2-pZH-view-40p-Va-Hre" nib but didn't get a UITableView.'
nib refers to the screen in the storyboard that your class is hooked up to. This looks like one of your classes has a UITableView but didn't have a corresponding one in the storyboard. You can try downloading the project files for comparison to start, but let us know if you need more help.

That should link to a zip of all my code. Eagerly awaiting your thoughts!

3,411 PointsI just noticed that part of the code is commented out in the SignUpViewController.m file in that upload.

Treehouse TeacherCool - got it! I had a hunch of what the problem was, but let me walk you through my troubleshooting in case it can help you.
- I first ran the app to see the error myself (after uncommenting in SignUpViewController).
- Then I inserted breakpoints in
viewDidLoadof Inbox and Login ViewControllers. - Ran the app again. It went into InboxViewController just fine. Stepped through the code, and it crashed when trying to perform the segue into LoginViewController.
viewDidLoadof LoginViewController was never called, which told me that there was a problem in the scene at the end of that segue. - Checked the details of that scene and noticed that it had the wrong class linked to it:
- Switched the class to LoginViewController. Verified the fix!
Hope this helps, and good luck with the rest of the course!

3,411 PointsI hate myself for such an obvious and silly mistake. Thank you very much for taking the time to help, it is greatly appreciated.
I didn't realise just how good the "after support" would be here it's fantastic. Looking forward to progressing with the material & thank you once again.

Treehouse TeacherDon't hate yourself; consider it a badge of pride because even the most experienced developers make obvious and silly mistakes now and again. Onwards and upwards! :)

3,411 PointsI don't understand what you mean though?
I don't at all understand how to seek out & find the one causing the problem.

Treehouse TeacherIt is confusing! Basically, one your your ViewController class files is expects a UITableView. The ViewControllers are connected to screens in the storyboard file, so one of those screens must be missing a UITableView. Perhaps it's even something you dragged or changed by accident.
If you'd like, zip up your project and either post a link here (Dropbox, maybe) or send it to help@teamtreehouse.com and I can help you troubleshoot with your actual code.
