🔨 Since Xcode 16 is now available, I’ve summarized some of the key features:

• Buildable folders. Great addition if you are tired of constant conflicts in your project file.

• New Tinted Icons. iOS 18 introduces dark and tinted app icons. Make your designers happy!

• Swift Strict Concurrency. Mode that helps you find and fix data races at compile time.
- Article about enabling the flag (SWIFT_STRICT_CONCURRENCY) in settings.
- Bunch of useful articles that will help solve all migration problems.

• Swift Testing. New library allows you to write tests with more confidence and less code.
- Tool for converting tests to the new format.
- Watch out for performance issues.

• Xcode Previews
- You no longer need to create a container for holding properties, thanks to a new macro.
- Note that Xcode 16 no longer sets ENABLE_PREVIEWS. It’s more reliable to use XCODE_RUNNING_FOR_PREVIEWS

• Editor Config. Finally, we can customize editor settings and share them across the team.

• Explicitly built modules. That makes builds faster and compiler errors more informative (though not always).

• Swift 6. New features are waiting for you to adopt!

and Friendly reminder to add iOS 18 to Introspect implementation. 🩷

Discovered one more way to theme applications using ShapeStyle. It's 100% SwiftUI-way, doesn't involve UIColor.init(dynamicProvider:) and can be achieved without using Xcode Asset Catalog (it’s not bad, but in case you want to programmatically initialize dynamic colors).

When using a modular architecture, consider checking the ENABLE_MODULE_VERIFIER project setting. Disabling this flag can significantly reduce build times, especially in projects with a large number of modules. While it is useful for identifying issues with frameworks before distribution, it may not be necessary for most general projects.

In interviews, questions about the stack and heap are common, excpecially where is what object stored? You can impress the interviewers by discussing trivial types in Swift. Mention that you can use an underscored function to determine whether a type involves heap allocations and reference counting or not.

// POD - Plain old data
_isPOD(Int.self) // true

What a huge update with Swift 6 – it's packed with cool new features! A lot of the updates are all about making concurrency smoother and more efficient, which is super exciting. Plus, there are other great improvements and language tweaks that make coding in Swift even better.

Stephen and Brandon wrote an article to address common questions and misconceptions about the Composable Architecture (TCA). They aim to clarify its benefits, its relationship with SwiftUI, and its suitability for various apps. The article also tackles comparisons with Redux, and concerns about complexity, performance, and boilerplate code. Additionally, it discusses action modeling and state management efficiency within TCA.

Apple’s released Swift 5.10 – it's making concurrent programming safer with full data isolation. This milestone sets the stage for Swift 6, which will enforce data isolation by default, improving usability and eliminating data races.

The more developers transition to strict swift concurrency, the more valuable articles like this will become, where non-obvious bugs and their solutions are discussed. In this article, the author shared how he experimented with @unchecked Sendable — describing a crash and how he fixed it, so we don't fall into the same trap.

We use auto-generated passwords daily, but have you ever wondered how they're designed? Apple’s approach combines two-syllable patterns, symbols, and numbers to create strong, user-friendly passwords that are easy to remember and type, even on different keyboards, while maintaining high security (71 bits of entropy). With consonant-vowel patterns, these passwords are simpler to recall in short chunks, making them practical even for entry on unfamiliar or foreign keyboards.

I came across an article on shared dictionary compression for network requests, which reduces the payload by transmitting only the changes instead of the full data each time. This technique is particularly useful for apps like calendars or news feeds, where most of the data remains the same between requests.

‼️ Friendly warning. Be aware of a crash in iOS 18 when using withCheckedContinuation while building with Xcode 16. You can temporarily switch to withUnsafe*Continuation to avoid the issue or build your app using Xcode 15 for now.

p.s. Seems like it’s only related to building an app for “My Mac (Designed for iPad)" destination

Xcode 16 brings a lot of updates - I want to share some of them that I find interesting:

- Predictive code completion
- Support for EditorConfig
- Explicitly built modules - more actionable error messages, improved debugger performance, and better scheduling decisions which maximize parallelism. LLDB can now import explicitly-built Swift and Clang modules directly
- A new code deduplication algorithm brings additional code size savings and an improved static link time performance
- New execution engine for Previews - shared build products between Build and Run and Previews, switching between the two is instant
- Previews now support previewing views inside of static libraries
- You can cut text from the Source Editor, and then use the “New File from Clipboard” to quickly extract part of a source file into a new file
- Buildable folder references - only record the folder path into the project file without enumerating the contained files. This minimizes diffs to the project when files are added and removed, and avoids source control conflicts with your team
- Swift-DocC now warns about documentation for parameters and return values that doesn’t exist for that documented API
- A lot features in Instruments
- Swift Testing - an all-new testing framework built for Swift from the ground up
