THIS WEEK'S BLOG POST
I'll be giving a talk in January next year covering lesser-known Swift features. @dynamicCallable is an attribute I didn't know how to use just yet, so I decided to dive in and see how it works. While it's primarily used for interpolation with languages like Python and Javascript, I'm motivated to see how it can be used in general.

CURATED FROM THE COMMUNITY

SWIFT

I’ve built several command-line tools but never tested them through Xcode. After reading this article from Marco Eidinger ‍, I’m reconsidering that approach since these are helpful tips.

While nothing is set in stone, this article by John Mccall gives you a look into the plans for Swift in 2023. A bigger picture is drawn based on input from workgroups and developers working on Swift. Exciting stuff is coming!

SWIFTUI

While reading this article by Daniel Saidi, I kept thinking there’s still value in using UIKit. Custom solution using complex gestures and advanced scroll-based animations: I’ll likely still use UIKit. However, this article gives insights into solving complex gestures using SwiftUI, which might be enough to keep you away from UIKit land.

It’s a hot topic to discuss navigation in SwiftUI. Point-Free released a significant update to their navigation solution, which can be inspiring at a minimum.

XCODE

I enjoyed reading this well-described journey of reducing the app size by optimizing images. Arnaud Joubay describes each step, slowly decreasing the size used by taking several steps like stepping away from PDFs and reducing image sizes.
