How to change font of UIButton with Swift

Question

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.

For Swift 3.0:

button.titleLabel?.font = UIFont.boldSystemFont(ofSize: 16)

where "boldSystemFont" and "16" can be replaced with your custom font and size.

Dot-notation is awesome 👌

btn.titleLabel?.font = .systemFont(ofSize: 12)

You don't need to force unwrap the titleLabel to set it.

myButton.titleLabel?.font = UIFont(name: YourfontName, size: 20)

Since you're not using the titleLabel here, you can just optionally use it and if it's nil it will just be a no-op.

I'll also add as other people are saying, the font property is deprecated, and make sure to use setTitle:forControlState: when setting the title text.

In Swift 5, you can utilize dot notation for a bit quicker syntax:

myButton.titleLabel?.font = .systemFont(ofSize: 14, weight: .medium)

Otherwise, you'll use:

myButton.titleLabel?.font = UIFont.systemFont(ofSize: 14, weight: .medium)
