DAY 49
Project 10, part 1
You’ve had a couple of days away from following projects, and I hope you used them to review what you’ve learned, write your own code for a while, and reflect on what was said in yesterday’s videos.
As the late, great Zig Ziglar said, “there are two sure ways to fail: think and never do, or do and never think.” Well, today is very much back to being a “do” day: we have a new project to build, which in turns means some new techniques to learn.
In particular, we’re going to go even deeper into Codable so you can get a feel for what’s happening behind the scenes when Swift can synthesize functionality for us. This is another step towards demystifying Swift and SwiftUI – it’s great to be able to rely on our tools to do work for us, but it’s also important to understand what they are doing.
Today you have five topics to work through, in which you’ll learn about custom Codable implementations, URLSession, the disabled() modifier, and more.
- Cupcake Corner: Introduction
- Adding Codable conformance for @Published properties
- Sending and receiving Codable data with URLSession and SwiftUI
- Loading an image from a remote server
- Validating and disabling forms
