Swift 4

   func setCharacterSpacing(characterSpacing: CGFloat = 0.0) {

        guard let labelText = text else { return }

        let attributedString: NSMutableAttributedString
        if let labelAttributedText = attributedText {
            attributedString = NSMutableAttributedString(attributedString: labelAttributedText)
        } else {
            attributedString = NSMutableAttributedString(string: labelText)
        }

        // Character spacing attribute
        attributedString.addAttribute(NSAttributedStringKey.kern, value: characterSpacing, range: NSMakeRange(0, attributedString.length))

        attributedText = attributedString
    }        

}

Swift 3

let label = UILabel()
let stringValue = "Sample text"
let attrString = NSMutableAttributedString(string: stringValue)
attrString.addAttribute(NSKernAttributeName, 2: style, range: NSRange(location: 0, length: stringValue.characters.count))
label.attributedText = attrString
