Hi folks,
This week we’re focusing on error handling by linking two articles (from the same author) on the topic. As usual SwiftUI is at the center of the UI/UX section, with some Canvas drawing, NavigationLink API enhancements and component styling.
And, we haven’t forgotten the (almost obligatory) Mac-related article!
Enjoy!

Unlocking the Real Power of Swift 6’s Typed Throws with Error Chains
Cihat Gündüz offers a thoughtful exploration of Swift 6’s typed throws feature. This post addresses the challenges of error propagation in layered applications by introducing a custom protocol to simplify error handling while maintaining the context.
Swift Error Handling Done Right: Overcoming the Objective-C Error Legacy
In another article Cihat Gündüz looks at another pitfall in Swift development: the challenge to display custom error messages correctly due to how Swift bridges to Objective-C’s NSError. He offers a craftier and friendlier approach to error handling by adding a custom protocol.
UI/UX
Styling Components in SwiftUI
What a piece of art done by Kasper Lahti! Customization might be painful, but not for this guy. We were lucky to attend his talk at NSSpain in person, as it was one that we can still recall pieces of.
Drawing symbols with Canvas
This article by Antonella Giugliano introduces drawing with symbols in SwiftUI’s Canvas with clarity and purpose. It makes a complex topic feel approachable. A solid read for anyone exploring custom rendering in SwiftUI.
Using equatable() to Avoid the NavigationLink Pre-Build Pitfall
This post not only highlights the issue that NavigationLink has (it renders the linked view in advance, which can be a bottleneck in some scenarios), but also resolves it in a clear and concise way.
SwiftUI ForEach Explained with Code Examples
Antoine van der Lee offers a clear and practical explanation of how to use ForEach with indices in SwiftUI. There are useful code examples for some of the most common use cases.
Create a fully custom About window for a Mac app in SwiftUI
Natalia Panferova provides a comprehensive guide on designing a personalized About window for macOS applications using SwiftUI. It details how to replace the default About panel with a custom AboutView, offering full control over layout, content, and appearance.

Thinking of WWDC
And to round it all up, we highly recommend checking out this insightful reflection from Daniel H Steinberg on WWDC or WWDC. It’s definitely worth the read!
