Mastering Swift 2 Programming (Video 11)

The video explores Swift extensions, demonstrating how they can enhance existing classes and types. It uses the Game of Life to illustrate cell neighbor identification and refactoring code into smaller functions. The video also covers creating utility extensions for Swift types, emphasizing the importance of meaningful extensions. The next video will delve into generics for more flexible extensions.

How does the extension for the string type improve functionality?

What considerations should be made when extending a type in Swift?

In what ways can generics enhance the implementation of extensions?
