Answer 1

A simple solution working for me: make the multiline button to respect its title height in Swift 4.2 by adding a constraint for the button's height based on its title label's height:

let height = NSLayoutConstraint(item: multilineButton,
                               attribute: .height,
                               relatedBy: .equal,
                               toItem: multilineButton.titleLabel,
                               attribute: .height,
                               multiplier: 1,
                               constant: 0)
multilineButton.addConstraint(height)
