Mastering Swift 2 Programming (Video 8)

The video explores protocol oriented programming in Swift, highlighting its advantages over traditional inheritance. It discusses the differences between structs and classes, emphasizing the benefits of using protocols for code extensibility and reuse. The introduction of protocol extensions in Swift 2 is explained, showcasing how they allow for extending types and adding functionality without modifying individual subclasses. The video concludes with a brief overview of type constraints in protocol extensions and provides additional resources for further learning.
