Swift get and set methods as well as read-only properties (computed properties, which do not save data by themselves, are calculated to obtain results)

Import UIKit

Class Person:nsobject {

Private var _name:string?

var name:string? {

get {

return _name

}

set {

_name = newvalue

}

}

The following notation will cause a dead loop

var num:string? {

get {

Return Self.num

//        }

//

set {

Self.num = newvalue

//        }

//    }

Read-only properties (also known as computed properties, overriding the Get method only)

var title:string {

get {

Return "Mr" + (name??) "")

}

}

Read-only attribute shorthand

var title2:string {

Return "Mr XXX"

}

}
