Answer 1

For Swift 5 the syntax is:

button.setImage(UIImage(systemName: "search"), for: .normal)

You can also set the weight of the icon by adding SymbolConfiguration:

let boldConfig = UIImage.SymbolConfiguration(weight: .bold)
let boldSearch = UIImage(systemName: "search", withConfiguration: boldConfig)

button.setImage(boldSearch, for: .normal)

See: Apple documentation for available names (API column) or go to InterfaceBuilder, select UIButton and in Attributes Inspector select Image which will give you list of all available icons.
