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 […]

In an earlier article, I explained how variables are defined in Swift using let and var. Both constants (let) and variables (var) in Swift always have a type; it’s what makes Swift a strongly typed language. For example, we could define a String variable like this: // the compiler will know myString is a String […]

In Xcode 16, this error actually is sometimes presented as "Passing closure as a ‘sending’ parameter risks causing data races between code in the current task and concurrent execution of the closure". The cause is the exact same as what’s covered in this post. Once you start migrating to the Swift 6 language mode, you’ll […]

Environment values are a convenient way to pass data down a deep view hierarchy. We can add values to the environment ourselves, but the syntax is clunky and verbose. In this post you’ll learn about the built-in @Entry macro which makes adding new values a breeze.

let and var are two ways to declare properties in Swift. Let’s explore their uses, and how their behavior will change depending on where they’re used.
