Just published a new article on a Sunday, like the good old days when I used to write weekly Swift articles 😀 This one is about getting started building a design system for an iOS app: https://www.swiftbysundell.com/articles/building-a-design-system-at-genius-scan

@florian Right, which doesn't make much of a difference when targeting Apple's platforms, but still, might be worth adding an explicit note about that within the article. Thanks for the feedback!

New article about a bit of a hidden gem within Swift's built-in Codable API - CodableWithConfiguration, which is super useful when we need to decode a type which requires additional data not present in the JSON (or whichever other data we're decoding from): https://www.swiftbysundell.com/articles/decoding-swift-types-that-require-additional-data

It's time for a new article! 😀 This time, I'm sharing some tips and tricks for when using SwiftUI's ViewBuilder to create custom container views. Hope you'll enjoy it, and happy Friday!

This time, it took me just two weeks (instead of two years 😅) to publish another new article!

Here's "Using Swift's defer keyword within async and throwing contexts", hope you'll find it useful 👍

Replying to @dmcgk@mastodon.ie
@dmcgk I would *love* to do that, but I barely have the time for one website, so I don't think starting another one is a good idea at this point 😅 But I do want to write articles comparing Swift and Rust, perhaps talk about inter-op, and so on.

Yesterday, I didn't just announce that Swift by Sundell is back (🎉), but I also published the first new article on the website in two years - about modern URL construction using the latest Foundation APIs and a custom extension/macro!

Hope you'll enjoy it 😀
