Setting global font in swift

Question

I create an extension where I set custom font

extension UILabel {
    var substituteFontName : String {
        get { return self.font.fontName }
        set {
              self.font = UIFont(name: newValue, size: self.font.pointSize)
        }
    }
}

but I have a problem: I get a error Unexpectedly found nil while unwrapping an Optional value, but if I set static size like this

self.font = UIFont(name: newValue, size: 13)

I didn't get a error and fonts is changing. How can I set exactly size which was automatically

in set you have to use size: self.font?.pointSize ?? UIFont.labelFontSize — Hardik Kardani

The font attribute is actually implicitly unwrapped UIFont!, so you should change your set to:

self.font = UIFont(name: newValue, size: self.font?.pointSize ?? UIFont.labelFontSize)
