Swift Generics

This lesson is part of Swift · All levels

Summary

This lesson discusses Generics in Swift which allows for flexible and reusable writing of functions and data types for different data types while maintaining type safety. Developers will study type parameters (<T>), generic constraints, and associated types on the protocol.

Key points

Generics avoid writing duplicate code for many different data types
Type parameters are written in the corner curve, for example '<T>'
Support Type Constraints to restrict types to meet certain protocols (e.g.: <T: Equatable>)
Built-in collections such as Array and Dictionary are entirely generics-based.
