Get to Know Your Protocols 6 lectures 32:00 The Course Overview This video provides an overview of the entire course. Exploring Protocols Before learning about how to define and use protocols, In this video we will start by exploring what protocols are in Swift. • A brief overview of what protocols are • The various declarations that a protocol can require • An example of the wide range of protocols in the standard library Defining and Conforming to Protocols In this video, you will be shown how to define and conform to your own protocols. • How to declare different requirements in a protocol • What the get and set declarations mean for property and subscript requirements • Access level rules for conforming to requirements Extending Protocols In this video, you will be shown how to extend protocols. • Writing implementations that can be used on any type of conforming protocol • Creating default implementations for protocol requirements • How to refer to other protocol requirements and extension implementations within a protocol extension Why Use Protocols? In this video, we will be covering some of the great advantages of using protocols in your code. • Encourages the use of value types • Provide functionality for all types that conform to the protocol through protocol extensions • Not monolithic and you can retroactively conform types to protocols Using Protocols as Types In this video, you will be shown how to use protocols as types. • Using protocol types to express any type that conforms to a single protocol • Using protocol types to express any type that conforms to multiple protocols • Using existential metatypes to express any metatype for a given type that conforms to one or more protocols Get to Know Your Protocols 6 lectures 32:00 The Course Overview This video provides an overview of the entire course.
