What Hacker News says
9 sourcesIf you'd like an example of how this can be done, Swift's AttributedString type is exactly that. It manages the association of runs of attributes (font, kerning, color, etc.) with Unicode text, and its backing storage uses a rope type provided by the swift-collections package. (The rope module itself isn't stabilized yet, so it's really only used for AttributedString at this point, AFAIK.)

They started late, but isn’t https://github.com/apple/swift-foundation paying serious attention to non-Apple platforms now?
SwiftUI, I think, isn’t as essential, as it isn’t really possible to create a good cross-platform Ui library (and yes, that means I think running iOS apps on MacOS can’t provide an optimal experience)
In Swift is a more convenient RustHow recent were your experiences?
The server-side Swift ecosystem has matured over the past few years, with specific attention from teams at Apple.
For example, regarding JSON, there has been a rewrite of the JSON encoder/decoder that results in a 200% - 500% speed up in deserialization! You can read about the (still ongoing) improvements to Foundation at https://github.com/apple/swift-foundation
Regarding logging, Apple has been pushing the development of community around the swift-log package at https://github.com/apple/swift-log. Maybe you’ve seen this, but just wanted to share!
One last thing: the Swift VSCode extension is actually really good! Not sure when you used it last, but I’ve been using it on a regular basis and it’s been great — and is only getting better. Here’s the link to the extension if you’re curious: https://marketpla

It’s true that Swift has had its various issues, but there’s a very real push by the core team and community to bring the language to new heights and places. Cross-platform support is getting better and better (check out what The Browser Company is doing with Swift on Windows) and a big source of performance bottlenecks are being addressed with the development of non-copyable and non-escaping types (Rust-like move-only types)!
Sorry that’s a lot, but I just wanted to point out that there’s a lot of hope in Swift and really interesting things are happening for the project!
> It continues to grow, and it's a rewrite, so it certainly proves your assertion wrong.
Which assertion was wrong? I was paraphrasing from the project page itself:
"It is in its early stages with many features still to be implemented." https://github.com/apple/swift-foundation
In 9 years of Apple text editor solo dev> The linux version of swift replicates a large number of native mac frameworks using whatever mix of C and C++ gets the job done.
Note that this is changing, on Darwin and Linux alike. Foundation.framework is transitioning from being a Swift interface over a C / Objective-C implementation to an Objective-C interface over a Swift implementation (https://github.com/apple/swift-foundation).
The language still has native C interop, and is gaining the same for C++, so it can delegate stuff like crypto to existing solutions like BoringSSL, but Swift-native solutions are becoming more common.
In An aborted experiment with server SwiftSomething not noted in the article is that any binary which links Foundation, even if otherwise written entirely in Obj-C, now uses Swift. This is due to the Foundation Swift rewrite effort (https://github.com/apple/swift-foundation) that is rewriting Foundation is Swift while maintaining Obj-C ABI compatibility.
