Concurrency Step-by-Step: Conforming to Protocols
If there’s one topic that I find intimidating, it’s protocols. They are very powerful and in extremely wide use. But I’m sitting here, trying to figure out how to lead into this discussion and I’m alr...

I finished up another in my "Concurrency Step-by-Step" series. This one is about everyone's favorite: protocols!

I’m noticing a lot more packages using versioned Package@swift-xyz.swift files, seemingly unnecessarily. This is a weird trend. Unless I’m missing something?

I try my best to sell unwanted stuff locally. Not for the money, just to be I dunno, less wasteful somehow? I've done it a lot, and it usually goes really well.
So. Today, let me tell you, it did not go well.

The #swiftlang toolchain is now available on Amazon Linux 2023.
Two years after my first commit allowing Swift to compile on Amazon Linux 2023, it took a while team effort to make this happen.

Learning why you need to use @.MainActor is much easier than learning why you need to use nonisolated.

Over the last few months, a bunch of promising leads haven't worked out. These things can take months, so who knows? But in the meantime, I have room for more work.

When building commercial, closed-source SDKs, it's important to decouple the build from your local environment, to mitigate the risk for build errors and malware. This post shows how to set up GitHub Actions to build the XCFramework & dSYMs of a binary Swift Package.

@khanwinter.com I’ve been doing a little ATProto work, and your CBOR library is really cool! Still very early, so I don’t have a lot of experience yet. But wanted to say thanks regardless!

Working on a side project. Just (barely) enough progress that it remains interesting. Just enough complexity that it feels like it’s got some kind of personal vendetta against me.

Number one thing I look for in technical blog posts is the author saying they were confused, made a mistake, and/or still don't understand something. It makes you seem human, which is good. But it's also such a strong indicator of good information.

Indie developers now have more tools in their toolkit for building with Swift across platforms, thanks to Skip. Exciting to see a Swift community member building a business with the open source Swift SDK for Android. skip.tools/blog/skip-fu... #Android

Since the launch of the official Swift SDK for Android on swift.org last month, we have been overwhelmed by a surge of interest in building cross-platform apps using a single shared SwiftUI codebase. ...

Ok, #ATProto PDS question.
I have to put "com.atproto.sync.subscribeRepos" behind a redirect (AWS API Gateway does not support HTTP and WS for a single domain). I understand the spec says maybe, maybe not. But does anyone know if the important existing relays will work with this?

A lot of Swift compiler bugs have been fixed recently. Not 100% sure these will all make it into 6.3, but great to see regardless.
I have a long list and I’m looking forward to checking when a beta comes out.
