The SIGABRT isn't the real error. It's just an indication your app crashed itself. There are actually two errors, listed above the backtrace:


>> Unknown class ViewController in Interface Builder file.

>> [<UIViewController 0x7fa4d3e09f00> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key pickerView


The first is a storyboard loading error, and the second is a Cocoa exception (which caused the app to crash itself).


The most likely reason for these is that you have a view controller that had an outlet called "pickerView", which used to be called "ViewController", and you changed its name to something else in the source file, but forgot to change the class name for the corresponding scene in your storyboard.


Or, it may be that you have the correct view controller class name in the storyboard, but the wrong module name. Normally you make sure "Inherit module from target" is checked, and you should see the correct module name in the text field below the class name.
