Mastering Swift 2 Programming (Video 10)

This video tutorial covers the construction of an application using lazy variables, closure expressions, and function value types in Swift. It begins with an overview of the topics, followed by a detailed explanation of lazy variables and their initialization. The video then demonstrates how to create and use lazy variables, explores function types and closure expressions, and concludes with a discussion on memory management and weak references to prevent memory leaks.

What does 'self' mean at the top of a closure, and why is it important?

Discuss the process of removing logic from an initializer using lazy variables.
