How to change font of UIButton with Swift
Dot-notation is awesome ð
btn.titleLabel?.font = .systemFont(ofSize: 12)
For Swift 3.0:
button.titleLabel?.font = UIFont.boldSystemFont(ofSize: 16)
where "boldSystemFont" and "16" can be replaced with your custom font and size.
Use titleLabel instead. The font property is deprecated in iOS 3.0. It also does not work in Objective-C. titleLabel is label used for showing title on UIButton.
myButton.titleLabel?.font = UIFont(name: YourfontName, size: 20)
However, while setting title text you should only use setTitle:forControlState:. Do not use titleLabel to set any text for title directly.
