Does not run, gives 'Thread 1: breakpoint 1.3' error and I don't know why

Here is the error I get when I try to run the programme after following the instructions on the video : http://i.imgur.com/CmDWvg1.png

I really don't know why it does not run and give this issue. Also it doesn't seem to find the 'PageController' class when selection in the inspection window for the view.

Thank you for any help.

It's not an issue, it's just stopping where you asked it to. Do you see those blue arrows in the sidebar? Those are called "breakpoints", and they'll stop your code when it hits where it is so you can jump in and take a peek at things like what variables have what values. They're super useful for when you're trying to figure out what's going wrong with your app, but you don't want them on when you want your app to just run. You can right click on them and hit either "Delete Breakpoint" or "Disable Breakpoint", and your code shouldn't stop

Hey,

Thank you. I think that should work, can I also ask why does this give an error : http://i.imgur.com/jIDzLzB.png

It is literally the same code that is on the video. :|

Just set the first line of that initializer to self.page = nil and call it a day

What version of Xcode are you running? If you right click (or click with 2 fingers, if you're on a trackpad), you should see this popup menu:

If it says it's stopping at a breakpoint, that's what it's doing, and you should be able to make it not stop by doing that. Otherwise, it's an actual crash and a different problem

Also when I do delete/disable it, it still takes me to like thread 2 or thread 3 and those can't even be right clicked. Sorry that I cannot provide image of it.

You can upload a screenshot to a site like postimg.org, then copy the Direct Link it gives you, then come back to Treehouse and paste in that link like this: ![](https://postimg.org/your_link_here)

You can press ⌘-7 to see all the breakpoints you have set, and from there, you can disable/delete them
