Some really impressive work from my teammate Kevin here: https://forums.swift.org/t/the-future-of-serialization-deserialization-apis/78585
If you care about Codable and/or serialization in Swift in general, definitely check it out
Hello Swift Community, I’m happy to announce that I've been hard at work planning a potential future for serialization & deserialization APIs in Swift. It's clear from community adoption and feedback that Codable has had a lot of success in the years since it was added to Swift 4, but that it doesn’t satisfy some important needs. One of the foremost of those needs is performance more in line with programming environments that compete with Swift. As such, the main goal for this effort is to unlo...
Any of you interested in adding “case” for RawRepresentable structs to Swift?
I.e. if you're simulating an enum-like open struct using
struct Foo: RawRepresentable {
var rawValue: Int
static var bar = Foo(rawValue: 0)
static var baz = Foo(rawValue: 1)
static var boff = Foo(rawValue: 999)
}
you can instead do ‘em as
case bar
case baz
case boff = 999
Like for an enum. Bonus points if you make associated values work, I'm not sure I'd know how.
My first swift evolution pitch in a while, and my first Linux pitch ever :D
https://forums.swift.org/t/pitch-io-uring-support-in-swift-system-on-linux/78340
Hi folks! In keeping with Swift System's policy of not being cross platform, I'd appreciate feedback on this low level abstraction for io_uring, Linux's new-ish batch async syscall API. The "future directions" and "alternatives considered" sections are pretty extensive, so I expect there will be a lot to discuss 😃 Draft proposal link for people who prefer markdown: swift-system/NNNN-swift-system-io-uring.md at 7fff872441b6acb03bb8922300c09ef5f2afae2b · apple/swift-system · GitHub IORin...
Very exciting proposal from @glessard that I've been helping do infrastructure work in support of: https://forums.swift.org/t/se-0456-add-span-providing-properties-to-standard-library-types/77233
TLDR: safer alternative to withContiguousStorage/withBytes style methods that also eliminates the annoying pyramid of closures!
Hi everyone, The review of SE-0456 " Add Span-providing Properties to Standard Library Types" begins now and runs through January 28, 2025. In order to try this feature out, the proposal authors have provided toolchains: Toolchain for macOS: https://ci.swift.org/job/swift-PR-toolchain-macos/1713/artifact/branch-main/swift-PR-78561-1713-osx.tar.gz Toolchain for Linux (Ubuntu): https://download.swift.org/tmp/pull-request/78561/1217/ubuntu2004/PR-ubuntu2004.tar.gz Toolchain for Windows: https:/...
My favorite Thanksgiving tradition is a good language design debate ahead of the holiday. This time on improving the approachability of data-race safety: https://forums.swift.org/t/prospective-vision-improving-the-approachability-of-data-race-safety/76183
I care deeply about this problem, and I appreciate any thoughts, questions, and other constructive feedback you have to share!
Hello Swift Community! The Language Steering Group would like to gather feedback on a prospective vision for improving the approachability of data-race safety that @John_McCall and I have been working on. Vision documents help describe an overall direction for Swift. The concrete Swift changes for executing on the vision will come as a series of separate Swift evolution proposals, so specific details (e.g., specific syntax, API names, etc.) are less important than the overall direction. There ...

Every year, after #WWDC, I see myself considering to get on EVO App development, but life happens and always take my focus out of it. Does is it a still valid project?
