Hey, any idea when this content is likely to be updated for IOS8 or a workaround implemented? :)

Some elements in IOS8 are now deprecated as stated in the IOS developer library

The replacement is UIAlertController and UIAlertAction in iOS 8.

This will only work in iOS 8 though so if you want backwards compatibility with iOS 7 or lower then you need to continue to use UIAlertView.

In Objective C you would do something like:

UIAlertController* alert = [UIAlertController alertControllerWithTitle:@"My Alert"
                               message:@"This is an alert."
                               preferredStyle:UIAlertControllerStyleAlert];

UIAlertAction* defaultAction = [UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault
   handler:^(UIAlertAction * action) {}];

[self presentViewController:alert animated:YES completion:nil];

And in Swift.

let alert = UIAlertController(title: title, message: message, preferredStyle: .Alert)
    let action = UIAlertAction(title: "OK", style: .Default,
                              handler: { action in
                                          self.startNewRound()
                                          self.updateLabels()
                                        })
    alert.addAction(action)
    self.presentViewController(alert, animated: true, completion: nil)
