10,849 PointsThere can be a lot of causes for a SIGABRT, and the kicker is that they could be absolutely anywhere in your code. You'll need to manually debug your code, by placing breakpoints before the troublesome code and checking the variables at that point. Here's a quick guide:
Place Breakpoints
Place breakpoints strategically before the code you expect to malfunction. Place breakpoints by clicking on the line numbers to the left of your code.Run your app
When execution pauses, look through the variables displayed at the bottom in the debug bar, to see if anything's amiss. This could be an uninstantiated variable, optional unwrapping, or a bunch of other things.
Fix that issue!
If all else fails, you can upload your project to GitHub and I'll have a look at it for you.
Good luck!

10,849 PointsThere is never a magic bullet for SIGABRT errors. You have to manually debug it. If you want, I'll help you if you upload your project to something like GitHub.

10,849 PointsOkay, I can't make a good judgment from the limited info, but to me this looks like an issue with your IBOutlets or IBActions. Why not give those a check over, and if you're still stumped I recommend downloading Pasan's project files, opening both of the ViewController.swift files, and pasting them into a diff tool to see where the files are different. (This one works nicely). Just be sure to download the right version for where you are in the course.
P.S. I really recommend you learn how to use Git, it's great for keeping your projects on track and organized. Treehouse has a great course called Git Basics which you might want to check out. :)
