Here is a swift solution. Just add this custom class on the bottom of your file (or create a new file for it) and use MyLabel instead of UILabel when creating your label.
class MyLabel: UILabel{
override func drawTextInRect(rect: CGRect) {
super.drawTextInRect(UIEdgeInsetsInsetRect(rect, UIEdgeInsets(top: 0, left: 10, bottom: 0, right: 0)))
}
}
