Ever since its original introduction in 2019, SwiftUI has had really strong interoperability with UIKit. Both UIView and UIViewController instances can be wrapped to become fully SwiftUI-compatible, and UIHostingController lets us render any SwiftUI view within a UIKit-based view controller. However, even though macOS has had an NSHostingView for inlining SwiftUI views directly within any…
Swift 5.7 introduces a new, more concise way to unwrap optional values using if let and guard let statements. Before, we always had to explicitly name each unwrapped value, for example like this: class AnimationController { var animation: Animation? func update() { if let animation = animation { // Perform updates … } } }…
Combining Swift’s flexible generics system with protocol-oriented programming can often lead to some really powerful implementations, all while minimizing code duplication and enabling us to establish clearly defined levels of abstraction across our code bases. However, when writing that sort of code before Swift 5.7, it’s been very common to run into the following compiler…
Simon Støvring returns to the show to talk about how he built his new text editor Runestone, how to effectively manage an app’s settings, performance tuning, and implementing an app’s core logic as a stand-alone framework.

Today it’s been exactly five years since this website first launched, and what a journey it has been! When I started this website after having published weekly articles on Medium for a few months, I honestly had no idea what to expect. I wasn’t even sure if anyone would even find the site to begin…
A major part of the challenge of architecting UI-focused code bases tends to come down to deciding where to draw the line between the code that needs to interact with the platform’s various UI frameworks, versus code that’s completely within our own app’s domain of logic. That task might become especially tricky when working with…
