How do I change the letter spacing in a UILabel?

You can use the NSKernAttributeName attribute on an attributed string:

UILabel *label = [UILabel new];NSMutableAttributedString *text = [[NSMutableAttributedString alloc]                                    initWithString:@"127"];// The value paramenter defines your spacing amount, and range is // the range of characters in your string the spacing will apply to. // Here we want it to apply to the whole string so we take it from 0 to text.length.[text addAttribute:NSKernAttributeName              value:@-0.5              range:NSMakeRange(0, text.length)];[label setAttributedText:text];

The easiest way is to create a custom UILabel class and set the letter spacing from Storyboard.

open class CustomLabel : UILabel {    @IBInspectable open var characterSpacing:CGFloat = 1 {        didSet {            let attributedString = NSMutableAttributedString(string: self.text!)            attributedString.addAttribute(NSKernAttributeName, value: self.characterSpacing, range: NSRange(location: 0, length: attributedString.length))            self.attributedText = attributedString        }    }}

On swift implementation looks like

let text = "TIPS, ARTICLES & BEST OFFERS"label.attributedText = NSAttributedString(string: text, attributes: [.kern: 3.12])
