Detect textfield overflowing

I'd like to be able to detect when a UITextfield overflows it bounds.

I want to detect Horizontal overflow (since there is only 1 line).

I was thinking about counting the amount of characters and multiplying that with a default value for the letter width and see if that fits inside the textfield bounds but that wouldn't work due too the letter having different widths.

I am aware of adjustsFontSizeToFitWidth but I want to increase the width of the textfield instead of decreasing the font size.

Here is the code which first calculates the size of the text and then compares it to the label size:

let textSize: CGSize = self.label.text!.sizeWithAttributes([NSFontAttributeName: self.label.font])        
let isOverflowing: Bool = textSize.width > self.label.frame.size.width
