Develop iPhone App with Swift App Crash

I have completed the swift courses up until the one where you begin to make a simple iPhone app.

I follow the tutorials, adding a label and a button and using the button to change the label text. Whenever I run the app however I get an error:

"libc++abi.dylib: terminating with uncaught exception of type NSException"

Obviously I don't understand what this means and have no idea why it isn't working, as far as I can tell I am doing exactly what I am told by the tutorial.

Thanks :D

Difficult to say, but my first guess would be that you've got an orphan connection. Did you connect a button, then delete it, then add a button again?

Go to your main storyboard - at the top-right click the little arrow surrounded by a circle. That lists all the connections you have between your buttons and the code. You may have more links than are necessary?

Hope that helps!

Steve.

I worked out what it was, in creating an IBAction I forgot to set sender to none or something like that. Thank you for pointing out the circle-arrow though as I now know where and what this is.

Thank you for your help :)
