In the past, we had to use the withObservationTracking function to access properties and receive changes with willSet semantics. In Xcode 26 and Swift 6.2, we have access to an entirely new approach that will make observing our models outside […]

The bottom line of that post is that closures that aren’t @escaping […]

Swift 6.2 comes with some interesting Concurrency improvements. One of the most notable changes is that there’s now a compiler flag that will, by default, isolate all your (implicitly nonisolated) code to the main actor. This is a huge change, and in this post we’ll explore whether or not it’s a good change. We’ll do […]

Xcode 26 allows developers to opt-in to several of Swift 6.2’s features that will make concurrency more approachable to developers through a compiler setting called “Approachable Concurrency” or SWIFT_APPROACHABLE_CONCURRENCY. In this post, we’ll take a look at how to enable approachable concurrency, and which compiler settings are affected by it. How to enable approachable concurrency […]

Tons of languages have support for ternary expressions. In this post we learn what ternaries look like in Swift, and when we can replace them with if expressions.
