User Defaults are the go-to solution for Swift applications to store preferences that persist across launches of your app. It’s a key-value store backed by a property list (plist) file. Due to this type of backing store, you need to be aware of the supported storage types. There are a few best practices when working …

Thread dispatching and Actors: understanding execution
Actors ensure your code is executed on a specific thread, like the main or a background thread. They help you synchronize access to mutable states and prevent data races. However, developers commonly misunderstand how actors dispatch to threads in non-async contexts. It’s an essential understanding to avoid unexpected crashes. Before we dive deeper into the …
@preconcurrency: Incremental migration to concurrency checking
The @preconcurrency attribute is part of the tools that help you incrementally migrate to strict concurrency checking. When async/await was introduced by Apple, we were writing non-structured asynchronous code, mainly using closures. On our road to Swift 6, we must prepare our projects for strict concurrency checks done by the compiler. The SE-0337 proposal makes …
Picking your minimum iOS version to support
When a new iOS version arrives, it’s oftentimes a moment to reflect on the supported iOS versions and see to which minimum iOS version your project should be set. It’s an important decision in a developer’s job and not something you can do without reasoning. We can be fortunate with the iOS adoption rate in …
Value and Type parameter packs in Swift explained with examples
Type parameter packs and value parameter packs allow you to write a generic function that accepts an arbitrary number of arguments with distinct types. As a result of SE-393, SE-398, and SE-399, you can use this new feature from Swift 5.9. One of the most noticeable places of impact is the 10-view limit in SwiftUI, …
App Intent driven development in Swift and SwiftUI
App Intent driven development can help you architect your code for reusability. An app intent allows you to define an action or provide content as a result. Using intents, you can extend custom functionality and data to support system-level services like Shortcuts, Siri, Spotlight, and the Action button. You might have created App Intents Spotlight …
If and switch expressions in Swift
Swift 5.9 introduced if and switch expressions that allow you to write shorter code by omitting the return keyword. The feature resembles Swift 5.1’s ability to omit the return keyword in single expressions inside closures. While shorter code doesn’t necessarily always lead to more readable code, omitting return keywords inside if and switch expressions certainly …
SwiftSyntax: Parse and Generate Swift source code
SwiftSyntax is a collection of Swift libraries that allow you to parse, inspect, generate, and adjust Swift source code. It was initially developed by Apple and is currently maintained as an open-source library with many contributors. You can find documentation on swiftpackageindex.com and many articles in the GitHub readme. The SwiftSyntax library is the foundation upon …
Build performance analysis for speeding up Xcode builds
Build performance can be analyzed in Xcode to speed up your builds. This can quickly speed up your workflow and save a lot of time during the day for all developers working on the project. Slow builds often distract us as they enable us to focus on distractions like social media and Slack. By investigating …
Xcode Debug Console Tour: Exploring All Options
The Xcode Debug Console allows you, as a developer, to explore logs and debug issues with your apps. All your logs will be printed out, and you can interact with the LLDB debugger as soon as your app pauses manually or due to a breakpoint. Xcode 15 introduced a new version of the debug console …
