Set a default value for UIPickerView in Swift?

This is the code I have used in one of my apps:

// Declare the outlet to the picker in your storyboard
@IBOutlet var myPicker: UIPickerView!

//...

override func viewDidLoad() {
//...
    myPicker.selectRow(row, inComponent: 0, animated: true)
}

Obviously, replace row and 0 with whatever values you want.
