Answer 1

If you are using Autolayout then no need to calculate height, just add leading,top and trailing constraint, set number of line to 0 for that label and line break mode to word-wrap, it will automatically update its height.

P.S. Add the bottom contraints too if there is any other control in nib after label.

You can use this :

var labelHeight : CGFloat
labelHeight = theLabel.boundingHeightForFixedWidth(theLabel.bounds.width)

Hope it help :)
