Understanding Swift KeyPaths

In this video, I want to introduce you to KeyPaths and how you can use them in your Swift projects. We will start by looking a what a KeyPath is and how you can use them to reference to a property of an object or a struct and then look at some examples of how you might apply them in your code. This will include using keyPaths for sorting and mapping arrays, we will look at the DynamicMemberLookup attribute and two very practical examples for using KeyPaths to simplify your code We will finish with a short explanation of how keyPaths are used in Lists for SwiftUI If you want to support my work, you can buy me a coffee :) https://ko-fi.com/stewartlynch Table of Contents: 0:00 Introduction 1:14 The Basics 5:40 KeyPathComparator 8:22 KeyPaths for Mapping 9:46 DynamicMemberLookup 15:50 Practical Examples 22:52 KeyPaths in Swift Lists Starter Project Files: (If you are having problems downloading zip files, use Safari.
