One of my favorite blogs is regularly sharing in-depth articles about SwiftUI. In their latest post, the author delves into the new CustomAnimation protocol, explaining what it is and how to use it effectively.

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.

There is a lot of criticism of GeometryReader in the iOS community: some try to avoid it, others consider it very useful, others don’t even know what it is. All these problems are discussed in a long article prepared by the author.

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.

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.

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.

This article is a great reminder to avoid using AnyView as much as possible, or use it carefully when really necessary. The author conducted some measurements of using AnyView (and without it) in lists and compared the results.

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.

Oh, look at this gem! Chris Eidhof from objc.io has built a guide for visually understanding how SwiftUI's layout system works. It's even possible to adjust some layout parameters to thoroughly grasp the consept.

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.

Great long-read of making a native text editor app as a solo dev (you probably heard or used it - Paper app).

In the second part the author concentrates on the deep-tech stuff - how text editing works internally.

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.
