Anoop's answer works like a charm. You can also do this in IB using User Defined Runtime Attributes:
- choose Button in IB
- Add Attribute
- KeyPath: titleLabel.adjustsFontSizeToFitWidth
- Type: Boolean
- Value: true

Set Minimumfontsize is not available in iOS8 use minimumscalefactor instead.

in Swift 4/5

Please make sure that yourBtn is available in @IBoutLet, not in action
in viewdidLoad or viewWillAppear

override func viewDidLoad() {
    super.viewDidLoad()
    yourBtn.titleLabel?.numberOfLines = 1
    yourBtn.titleLabel?.adjustsFontSizeToFitWidth = true
    yourBtn.titleLabel?.lineBreakMode = NSLineBreakMode.byClipping
}

For Swift 5.0

override func viewDidLoad() {
        
        super.viewDidLoad()
        // Do any additional setup after loading the view.
        YourButton.titleLabel?.numberOfLines = 1
        YourButton.titleLabel?.adjustsFontSizeToFitWidth = true
 
    }

Teetz's answer works like a charm. In case if you want to add margin between titleLabel of UIButton edges after it adjustsFontSizeToFitWidth, you can add few spaces before first character & after last character. So, that it looks neat.
