Text spacing - iOS

On iOS, you can use NSMutableParagraphStyle for paragraphs:

• lineSpacing: set spacing between lines
• lineHeightMultiple: multiply distance between lines by a number
• paragraphSpacing: set spacing between paragraphs

To adjust the spacing between letters you can use the NSKernAttributeName attribute.

let style = NSMutableParagraphStyle()
style.lineSpacing = 20
style.lineHeightMultiple = 1.5
style.paragraphSpacing = 20

let attributedString = NSAttributedString(string: "Appt", attributes: [
    .paragraphStyle:  style,
    .kern: 3.0
])
element.attributedText = attributedString
