Figure out size of UILabel based on String in Swift

Question

I am trying to calculate the height of a UILabel based on different String lengths.

func calculateContentHeight() -> CGFloat{
    var maxLabelSize: CGSize         


        

Answer 1

In Swift 5:

label.textRect(forBounds: label.bounds, limitedToNumberOfLines: 1)

btw, the value of limitedToNumberOfLines depends on your label's text lines you want.
