Answer 2

Lazy initialization (also sometimes called lazy instantiation, or lazy loading) is a technique for delaying the creation of an object or some other expensive process until it’s needed. When programming for iOS, this is helpful to make sure you utilize only the memory you need when you need it. This technique is so helpful, in fact, that Swift added direct support for it with the lazy attribute. To understand why this is useful, let’s first go over the old way of creating lazy properties.
