Using custom font for entire iOS app swift

Question

I know that to set a custom font of an element on the screen I can simply dosomeLabel.font=UIFont(name: "Exo 2.0", size: 15).

I was wondering how one could set it for an entire app using swift. (A hack would be to do what I know for every single element of the app but that is just going to be a maintainability nightmare)

I see that this question has already been asked with an objective-C tag, How to set a custom font for entire iOS app without specifying size but I'm not familiar enough with objective-C enough to port the code to swift

Answer 1

You can set the appearance of the UILabel and other UIViews:

UILabel.appearance().font = UIFont(name: "yourFont", size: yourSize)

More General:

AnyUIView.appearance().font = UIFont(name: "yourFont", size: yourSize)
