Generics are the most powerful features in iOS and Swift. Generics allow you to generalize and reuse code in ways that would be impossible otherwise.

Generics can be confusing but once you understand the concept, they will become your most trusted allies in Swift programming. Generics are quite an advanced features of iOS and iOS uses generics extensively. This guide is for you to understand generics from the most basic example to their use at the enterprise level app.

Learning Objectives:

- Why do we need Generics?

- What is a placeholder type in Generics?

- Creating first Generic function

- Type Constraints in Generics with Protocols

- Creating custom Generic type constraint

-Associated type in generics

- Generics in Protocols

- Generics in Enums

- Custom Collection Data Structure using Generics

- Discussion on how Swift Compiler handles Generics

- Generics to make everyday repeated task easy (Enterprise level application examples)

- Generic Network Manager

- Generic TableView

You will be building real examples and refactoring them to convert them into a generic version which can be used further by multiple different use cases by supplying the generic type.

You will learn to build generic tableview which will help you reduce boiler plate code to be refactored and abstracted away so you do end up writing same coder over and over. These example will help you understand generics better in much more practical sense.
