Weekly Swift articles, podcasts and tips by John Sundell.
A recap of the basics of SwiftUI, Apple’s declarative new UI framework for building apps across all of their platforms. How to build custom views and modify existing ones, how to manage local state within a view, and how to compose multiple views to form new ones.
Longtime Apple platforms developer Brent Simmons joins John to discuss how SwiftUI is ushering in a new era for Apple’s developer tools, and how we as third party developers can prepare for it. Also, Mac development, lots of tips for writing efficient code, and dynamic programming in Swift.
Deploying generics in a more gentle fashion — to make a code base simpler, not more complicated.
Kaya Thomas joins John to talk about Apple’s various accessibility technologies and how SwiftUI is taking things to a whole new level. Also, how UI testing and accessibility are closely related, and what makes declarative UI development so powerful.
This week, let’s take a look at a few techniques that we can use to prepare ourselves for undergoing major paradigm shifts when it comes to the APIs and technologies that we use to build apps — using the shift from imperative UI development with UIKit to the declarative nature of SwiftUI as an example.
SwiftUI brings a new, declarative way to build UIs for Apple’s platforms, and also pushes the Swift language itself to new limits — by making heavy use of a set of key new syntax features, that are being introduced as part of Swift 5.1, in order to provide a very DSL-like API. This week, let’s take a first look at those features and how they work.
It’s time for the 2019 Swift by Sundell WWDC special, featuring PCalc creator James Thomson — who, with his over 25 years of experience developing apps for Apple’s platforms, joins John to discuss SwiftUI, Catalyst, and the other exciting tools and frameworks introduced at this year’s WWDC.
