Thread 1 Signal Sigabrt

My program works until I click my buttons, I have deleted them and redone them... I have also checked them and they have no yellow warning triangle. Could you suggest what is wrong from this error message in Xcode please

If you're having a SIGABRT it's often, because you try to access something which is nil or doesn't exist. You have to read every line of the error message (or use cmd+F to search in the Text) to find the reason.

Here it's this:

setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key storyboard.

I think you're trying to set an value for an key in an dictionary, if this is not the error I'd recommend doing this:

  • ask question on stackoverflow.com
  • google around to find out about SIGALBRT errors (read about common errors, how to understand those error messages)

PS: If you want to make it show in this code format you have to use backticks like this: ` and not those ' or those ´
