🎉 10 years of open source Swift! A decade ago today, we opened Swift to the world with a simple blog post: swift.org/blog/welcome

What's grown since—thanks to an incredible community of contributors—has been extraordinary. Here's to the next ten years. 🧡

🏎️ While Swift was originally created for iOS/macOS apps, many might not realize that at Apple we run Swift on the server to operate massive services, on Linux, serving billions of requests per day. Check out our VP's keynote at AWS re:Invent for details youtu.be/JeUpUK0nhC0?...

Another year another great conference. So many exciting talks and some great announcements as well!

The new Swift configuration API makes the most of Swift's type checking and expressivity to make it eady to solve common config tasks. @czechboy0.dev walks us through its features @serversideswift.info

Really excited about this announcement! Looking forward to what everyone is going to build with this

Another Swift package has just dropped at the server conference! The Swift Temporal SDK is here, introduced by Franz Busch

let config = ConfigReader(providers: [ EnvironmentVariablesProvider(), try await JSONProvider(filePath: "/etc/config.json") ]) let httpTimeout = config.int(forKey: "http.timeout", default: 60) print(httpTimeout) // prints 15

Introducing Swift Configuration, a new way to share and manage configuration for Swift. It's a smarter way to keep secrets safe and separate develop/test/prod environments. More here: forums.swift.org/t/introducin...

Swift Configuration is going to change how we do configuration across our ecosystem. Can’t wait to see how everyone is going to use it!

Yeah we should get that over the line. @lukasa.hachyderm.io.ap.brid.gy is working on all the strict concurrency adoption in NIO right now.

Yes a third one is setting a task cancellation handler. Throwing a CancellationError is really just one way of indicating that something got cancelled but returning early is also totally fine.

If the task is cancelled before or while sleeping the method will throw a `CancellationError`. Now you can ignore the error with `try?` it still means your task supports cancellation.

I hope this cleared things up a bit.

Now the second documentation linked on `cancel()`:

"Calling this method on a task that doesn’t support cancellation has no effect"

Just because the `Failure` type is `Never` doesn't mean that the task doesn't support cancellation. For example `Task.sleep(for:)` checks for cancellation.

The above will print `true` since the task is indeed cancelled. The doc that @czechboy0.dev linked does show a conditional conformance; however, `Never` conforms to `Error`. You can actually see that all `Failure`s value most conform to `Error` here:
