ios - Thread error in IBAction while overriding prepareForSegue function

Question

I'm getting a thread error Thread 1: Breakpoint 1.1 in my IBAction function. The code runs without error, but when I click the button on the simulator, the simulator crashes and produces the breakpoint error. The affected code is:

@IBAction override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject!) {
    if testoEsercizio.text == "Per iniziare premi la tv" {
        var viewController : SecondoSchermo = segue.destinationViewController as SecondoSchermo
        viewController.stringaponte = "SI buono"
    } else {
        var viewController : SecondoSchermo = segue.destinationViewController as SecondoSchermo
        viewController.stringaponte = "NON buono"
    }  
}

Answer 1

Open the breakpoint editor in Xcode with ? + 7. From there you can see the breakpoints that are on (as indicated by dark blue) or off (with light blue). I highly suspect that you have a breakpoint set in your method.

The term Thread 1: Breakpoint 1.1 is the debugger's internal name for the breakpoint (I Assume you're reading this from the green bar of text?). It doesn't necessarily mean it is a threading error, it's just telling you where it stopped.

You can press ^ + ? + Y to Continue, or go to the Debug Menu and select other options. ? + ? + Y will bring up the Debug area and a bar of buttons which correlate to the Debug Menu's actions.
