What do you mean by lazy property in iOS?

Answer»

LAZY properties are properties whose initial value isn't computed until the first time they are used. Including the lazy modifier/keyword before the DECLARATION of a stored property indicates it is lazy. This lets you delay the initialization of stored properties. This could be a great way to streamline your code and reduce unnecessary work. When a code is expensive and unlikely to be called consistently, a lazy variable can be a great solution. 

Example: 

class PERSON { var name: Stringlazy var personalizdgreeting : String = {     RETURN “HelloScala \(self.name)!”  }() INIT(name: String) {           self.name = name            } }

As shown above, we aren't sure what value personalizedgreeting should have. To know the correct greeting for this person, we need to wait until this object is initialized.
