segmentedcontrol swift string

I have a problem with my swift application. I am trying to schedule a local notification and i am trying to add the repeat interval to the code. The user should select how oft the notification should appear with a segmented control. I cant figure out how to do that.

Here is my viewcontroller file.

import UIKit
class TodoSchedulingViewController: UIViewController {
@IBOutlet weak var titleField: UITextField!
@IBOutlet weak var deadlinePicker: UIDatePicker!
@IBOutlet weak var segmentedControl: UISegmentedControl!
@IBOutlet weak var textLabelrepeat: UILabel!

override func viewDidLoad() {
    super.viewDidLoad()
    textLabelrepeat.text = "Ingen gentagelser"
}

@IBAction func savePressed(sender: UIButton) {

Here is the first fail

let todoItem = TodoItem(deadline: deadlinePicker.date, title: titleField.text!, gentag: segmentedControl.gentag , UUID: NSUUID().UUIDString)

    TodoList.sharedInstance.addItem(todoItem) // schedule a local     notification to persist this item
    self.navigationController?.popToRootViewControllerAnimated(true) // return to list view
}


@IBAction func indexChanged(sender: UISegmentedControl) {
    switch segmentedControl.selectedSegmentIndex {
    case 0:
        textLabelrepeat.text = "Ingen gentagelser"

Here is the second fail

gentag.string = "notification.repeatInterval"

    case 1:
        textLabelrepeat.text = "Gentages dagligt"

    case 2:
        textLabelrepeat.text = "Gentages ugentligt"

    default:
        break;
    }


}

} 

In this code. Xcode come with 2 errors:

• Value of type 'UISegmentedControl' has no member 'gentag'
• Use of unresolved indetifier 'gentag'
