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
_isPOD(Array<Int>.self) // false

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.

I came across a great video about creating a Design System using the example of button styling. I particularly liked the approach of expanding a simple button with additional fields such as description and title by combining different styles.

Interesting approach for storing API keys by using on-demand resources with enabled prefetching instead of embedding them directly in code, that could lead to expose them as plain strings when extracted from IPA files.

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

I often find that developers are confused about which component is best for them: ZStack or overlay (+background). So I hope this short article will clarify the differences and help delve deeper into the unique properties of these two modifiers.

Clickbait news. Apple introduces new programming language!

… for writing configurations.

It combines the simplicity of static languages with the capabilities of general programming, featuring classes, functions, conditions, and loops. Pkl ensures safety with type checks, offers ease of use with IDE integration, and supports package sharing and integration into various programming languages.

As in the previous article the author once again made a really great job. This time he prepared an in-depth analysis of the ViewThatFits component, providing a detailed explanation of its functionality and the underlying reasons for its operation. Moreover, the author went a step further by recreating this component using the Layout protocol, showcasing both a profound understanding and practical application of the subject matter.

For those who already use the Logger type, Xcode 15 brings handy improvement — support of filtering console logs and more directly in Xcode, eliminating the need to launch the Console app. You can filter logs by their type (networking, ui), jump to code where a log message has been triggered and so on.
