Passing variables between View Controllers using a segue

Question

I use Swift and Xcode 6 and would like to pass a variable from one View Controller to another using a Segue.

I have created a segue called \'MainToTimer\' which is

Answer 1

In the first ViewController place this (for modal segue):

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
    let theDestination = (segue.destinationViewController as ViewController2)
    theDestination.Duration2 = Duration
}

Change ViewController2 to the name of the second ViewController. In ViewController2 create a class variable:

var Duration2 = (whatever the type - UInt8 I guess for time)

That's it. You will have in the value of Duration2 the value of Duration from the first ViewController.
