NSUserDefault and segue

ok so i have everything set up for my NSUserDefaults and its set up in my viewdidLoad

if (txt1TotalDefault.valueForKey("TextField1Total") != nil){
            TextField1Total = txt1TotalDefault.valueForKey("TextField1Total") as! Double
            let T1Total = NSString(format: "TextField1Total: %i", TextField1Total)
        }

i need to get T1Total out so i can put it into my segue

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
        var DestViewController : SecondViewController = segue.destinationViewController as! SecondViewController

        DestViewController.TotalMoneyLabel.text = T1Total
}

any suggestions

Instantiate the variable outside the viewDidLoad block as a class variable. 

var T1Total = NSString()
 override func viewDidLoad() {
        super.viewDidLoad()
        if (txt1TotalDefault.valueForKey("TextField1Total") != nil){
            T1Total = NSString(format: "TextField1Total: %i", TextField1Total)
        }
    }

Is there a reason you are using NSString? If there isn't a specific reason, switch to the NSUserDefaults string methods. Use Camel Case when naming variables and make your variables more descriptive if you can. You'll thank yourself later in larger projects.

let defaults = NSUserDefaults.standardUserDefaults()
var variableToPass = String()
override func viewDidLoad() {
        super.viewDidLoad()
       if defaults.stringForKey("keyNameFromDefaults") != nil {
           let valueFromDefaults = defaults.stringForKey("keyNameFromDefaults")!
           variableToPass = "This is the value from the user defaults: \(valueFromDefaults)"
        }
    }

i dont understand how to fix my problem still, there is no reason for the NSString and i cant get my code to work so that my label in another view changes to T1Total
