Learn more about Swift concurrency

The Xcode 16.3 beta is out, which includes a new version of Swift. Swift 6.1 is a relatively small release that comes with bug fixes, quality of life improvements, and some features. In this post, I’d like to explore two of the new features that come with Swift 6.1. One that you can start using […]

When you turn on strict concurrency checking or you start using the Swift 6 language mode, there will be situations where you run into an error that looks a little bit like the following: Main actor-isolated property can not be referenced from a Sendable closure What this error tells us is that we’re trying to […]

When Apple released Xcode 16 last year, they made the Swift 6 compiler available along with it. This means that we can create new projects using Swift 6 and its compile-time data race protections. However, the big question for many developers is: Is 2025 the right time to adopt Swift 6 fully, or should we […]

With Swift 6, we have an entirely new version of the language that has all kinds of data race protections built-in. Most of these protections were around with Swift 5 in one way or another and in Swift 6 they’ve refined, updated, improved, and expanded these features, making them mandatory. So in Swift 5 you […]

Once you start migrating to the Swift 6 language mode, you’ll most likely turn on strict concurrency first. Once you’ve done this there will be several warings and errors that you’ll encounter and these errors can be confusing at times. I’ll start by saying that having a solid understanding of actors, sendable, and data races […]

When you create a new Swift Package in Xcode 16, the Package.swift contents will look a bit like this: // swift-tools-version: 6.0 // The swift-tools-version declares the minimum version of Swift required to build this package. import PackageDescription let package = Package( name: "AppCore", products: [ // Products define the executables and libraries a package […]
