You have to use UITextView for this and use it's sizeThatFits method.

First you have to know how high line will go 

var totalLines:CGFloat = 5
var maxHeight:CGFloat = myTextview.font.lineHeight * totalLines

Then in your viewDidLoad method

myTextView.sizeThatFits(CGSizeMake(myTextview.frame.size.width, maxHeight))

You are doing wrong in your code. use this above code in viewDidLoad

 @IBOutlet weak var myTextview: UITextView!



    override func viewDidLoad()


    { super.viewDidLoad()
        let totalLines:CGFloat = 5

        let maxHeight:CGFloat = (myTextview.font!.lineHeight * totalLines)



        myTextview.sizeThatFits(CGSizeMake(myTextview.frame.size.width, maxHeight))

}

    override func didReceiveMemoryWarning() {

        super.didReceiveMemoryWarning() // Dispose of any resources that can be recreated. } }

}
