I’m having crazy horrible ideas that will make me lose my job before Sonet 4.6, but here I go: can I check at runtime where the current scope is executing? I.e. I want a boolean that represents if it’s in the main thread, or not #iosProgramming #swiftConcurrency

πŸš€ I just released Swift Streamable Actors v1.0!

If you’ve ever wanted to observe changes to a Swift Actor's state as an AsyncStream without writing 30 lines of boilerplate for every property, this macro is for you.

Key highlights: βœ… 100% Type-safe (no type-erasure/AnyKeyPath) βœ… Memory safe (static factories avoid strong reference cycles) βœ… Clean API: @Streamable does it all.

Check out the code: https://github.com/malhal/swift-streamable-actors

Looked at code using Swift Concurrency:

Immediately found a bug:

state = .working(progress: 0)
await doSomething() { percent in
state = .working(progress: percent)
}
state = .done

What’s the value of `state` now?
(β€œSurely `.done`” is the wrong answer)

Struggling with protocol conformance across actor isolation boundaries? Swift 6.2 introduces isolated conformances and protocol isolation features that can be tricky to navigate. This step-by-step breakdown helps you understand when and how to use these patterns correctly, making your concurrent code safer and more maintainable.

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 already getting overwhelmed. That’s because protocols can be incredibly complicated.

Singletons with Swift Concurrency

I see singletons used a lot in Swift projects. These things are, by definition, global state. That means they can be accessed from any context - any thread or actor - at any time. And this property makes them a common source of problems when used with Concurrency.
