Adjust UILabel height depending on the text

Question

Consider I have the following text in a UILabel (a long line of dynamic text):

Swift 2:

    yourLabel.text = "your very long text"
    yourLabel.numberOfLines = 0
    yourLabel.lineBreakMode = NSLineBreakMode.ByWordWrapping
    yourLabel.frame.size.width = 200
    yourLabel.frame.size.height = CGFloat(MAXFLOAT)
    yourLabel.sizeToFit()

The interesting lines are sizeToFit() in conjunction with setting a frame.size.height to the max float, this will give room for long text, but sizeToFit() will force it to only use the necessary, but ALWAYS call it after setting the .frame.size.height .

I recommend setting a .backgroundColor for debug purposes, this way you can see the frame being rendered for each case.
