A two-week effort to help support indie developers shipping apps on Apple’s platforms who have been financially impacted by the COVID-19 pandemic.
Let’s continue exploring the SwiftUI layout system by taking a look at a couple of more advanced techniques, such as how we can align views with dynamic dimensions and how to read a view’s geometry in order to build custom layouts.
Holly Borla and Grace Kendall, both software engineers at Apple, join John to go on a deep dive into the Swift Playgrounds app and Swift 5.2’s new diagnostics engine. Also, how Swift Playgrounds was ported to the Mac using Catalyst, and Swift’s role in education and as a language for beginners.
Let’s take a look at the SwiftUI layout system by starting to build a full-screen view from scratch. Along the way, we’ll use many different techniques and APIs, which lets us explore the underlying rules of the SwiftUI layout system.

This week, let’s take a look at a few different ways of configuring views when using SwiftUI, and the sort of pros and cons that each of those approaches gives us in terms of code structure and flexibility.
Meng To, founder of Design+Code, joins John to go on a deep dive into SwiftUI from a design perspective, and to talk about how developers and designers can build scalable and flexible UIs using it. Also, structuring view code and components, the power of modifiers, and how SwiftUI compares to other UI tools and platforms.
