When Hursh Agrawal published this video six months ago, he made a bold claim. He said they planned to create the Windows version of their Arc Web Browser using Swift, and it would have a native look and feel in terms of Windows UI and controls.

It was an ambitious plan, but it also made me want to watch what they were doing. It all made more sense when I learned that Saleem Abdulrasool had joined their company, presumably to lead this effort.

In case you’re not aware, Saleem is a Swift core team member and the driving force behind Swift on Windows and other efforts like SwiftWinRT and SwiftWin32.

I was happy (and just slightly surprised 😅) to see this update from Hursh at the end of last week. They seem to be making progress and even mention open-sourcing the cross-platform UI framework they are creating. If they are working on something that allows developers to share UI code across platforms and they follow through with platform fit being important, that framework could be a big deal.

Today, cross-platform Mac and Windows (and Linux) development is likely to mean using either Electron or Flutter. Both are fully cross-platform, but neither creates a great native-feeling UI.

Swift faces an incredibly challenging journey to be relevant as a language used for Windows development, but a Mac and Windows (and Linux?) UI framework that cares about platform fit would be unique in the industry and give it a nice boost. I’m looking forward to seeing what gets announced when Arc showcases it.

Note: I also considered including Xamarin.Mac and React Native for macOS above, but I had reasons not to include them. Xamarin.Mac creates AppKit apps and while it could help with a partially cross-platform codebase, you’d still need a separate UI layer for Windows. React Native for macOS doesn’t seem to have gained any traction since launching, and even the official desktop showcase has broken links and very few mentions of apps that work on macOS.

SwiftFiddle

I genuinely thought I had linked to this fantastic website from Kishikawa Katsumi before, but it appears that I have not! Think Swift Playgrounds on the web, with the ability to switch between Swift versions (including nightly snapshots) and shareable links so you can pass your code around. ❤️

Tips and tricks for exploring a new codebase

I’ve not had a traditional career in terms of joining companies to work on existing apps, so I’m confident I’d be terrible at learning a large codebase that I’ve not been involved with from the start. What a good job that Donny Wals has written up this guide on how to get better at it.

Flexible Continuous Integration for iOS

I really enjoyed this post from Michael Bachand and Xianwen Chen covering the history and current situation with CI at Airbnb. My only piece of advice would be to pay attention to this line in the post:

Our new CI system ran over 10 million minutes of CI jobs in the last three months of 2022.

This post is fascinating, but it’s likely you’re not dealing with the same scale of CI unless you are also at a huge company.

Attempting to connect a tvOS app to an iOS app

This post from Ben Dodson would have been right at home on NSHipster. I love reading about the more obscure APIs on iOS and, in this case, tvOS!

Parallax header effect in SwiftUI using CoordinateSpace

They may not be as popular today as they were, but a good quality parallax pull-down header can always be a valuable tool for design situations like user profile screens. Artur Gruchała has a great example here of putting one together in SwiftUI. 👍

Designing a Step Goal Live Activity

Why do I keep linking to David Smith’s posts on app design? Partially because he’s one of the few people blogging on this topic, but primarily because he’s making things like this! ❤️ It’s so well thought out and beautifully designed that I feel I must highlight it.

Note: If there’s anyone who is blogging about app design that I don’t know about, you know what to do!
