Im getting an error when trying to perform a variable assignment with my destinationViewController.

The error message is this:
Thread 1: EXC\_BREAKPOINT (code=EXC\_I386\_BPT, subcode=0x0)

This in my prepareForSegue function.

```
override func prepareForSegue(segue: UIStoryboardSegue!, sender: AnyObject!) {
    if segue.identifier == "LoginSegue"{

        let vc = segue.destinationViewController as LoggedInViewController
        vc.email = emailTextfield.text

    }
}

```

In the other file it looks like this.

```
var email: String?

```

which is at the top. 
Then this:

```
override func viewDidLoad() {
    super.viewDidLoad()

    println("Email is:")
    println(email)
    println("Email was")
}

```

But i never come into the second file.

It is the line let vc = segue.destinationViewController as LoggedInViewController that is marked with error.

Both swift files are connected to navigation controllers.

I dont know what more you need, but I will of course post all code you need to understand!

Thanks!
