2 BIG QUESTIONS

  1. what is wrong with this line of code:

  2. (IBAction)buttonPressed {

    int random = arc4random_uniform(self.predictions.count); self.prectionLabel.text = [self.predictions objectAtIndex:random];

  3. How do I Archive in Xcode? The button to Archive is not "pressable". How do I fix this?

Are you saying that buttonPressed should be hooked up to the Archive button, only the method is not firing when the button is pressed? Otherwise I'm not too sure what you mean by "Archive".

Hey Tomek!

You need to add a dash before your method implementation to specify that it's an instance method and it seems you've spelt prediction in predictionLabel wrong. Also, you need to close the body of the method with a closing curly brace.

- (IBAction)buttonPressed {
    int random = arc4random_uniform(self.predictions.count);
    self.predictionLabel.text = [self.predictions objectAtIndex:random];
}

As for archiving, make sure you have an actual iOS device selected in the scheme menu. You can't archive using the simulator.

Hope that helps!
