I’ve been working on some performance-critical Swift code, and you can get some amazing speedups using spans, BitwiseCopyable types, explicit non-copyable structs, and atomics from the Synchronization module.
That’s over a 400x speedup compared with Swift collection types and traditional kernel-based locking.

Amazing how time flies! Congratulations to the Swift team for an incredible decade of open source! 🎉
🎉 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. 🧡

ALT import Foundation let calendar = Calendar.current let openSourceDay = calendar.date(from: DateComponents(year: 2015, month: 12, day: 3))! let anniversary = calendar.date(byAdding: .year, value: 10, to: openSourceDay)! if calendar.isDateInToday(anniversary) { print("10 Years of Swift open source! 🎉") }

It is wonderful to see how much progress Swift has made so far, and exciting to see and think about how far it can go!

I use Swift for frontend (@streamieapp) and backend. Being able to share common code between those platforms has an enormous benefit.

In Swift 5.7 and later, we can use advanced clock APIs with clocks, instants, and durations to easily manage delays in asynchronous tasks with precise timing and power efficiency:

We've been evaluating a number of C++ successor languages for @ladybirdbrowser, and the one best suited to our needs appears to be @SwiftLang 🪶
Over the last few months, I've asked a bunch of folks to pick some little part of our project and try rewriting it in the different languages we were evaluating. The feedback was very clear: everyone preferred Swift!
Why do we like Swift?
First off, Swift has both memory & data race safety (as of v6). It's also a modern language with solid ergonomics.
Something that matters to us a lot is OO. Web specs & browser internals tend to be highly object-oriented, and life is easier when you can model specs closely in your code. Swift has first-class OO support, in many ways even nicer than C++.
The Swift team is also investing heavily in C++ interop, which means there's a real path to incremental adoption, not just gigantic rewrites.
Strong ties to Apple?
Swift has historically been strongly tied to Apple and their platforms, but in the last year, there's been a push for "swiftlang" to become more independent. (It's now in a separate GitHub org, no longer in "apple", for example).
Support for non-Apple platforms is also improving, as is the support for other, LSP-based development environments.
What happens next?
We aren't able to start using it just yet, as the current release of Swift ships with a version of Clang that's too old to grok our existing C++ codebase. But when Swift 6 comes out of beta this fall, we will begin using it!
No language is perfect, and there are a lot of things here that we don't know yet. I'm not aware of anyone doing browser engine stuff in Swift before, so we'll probably end up with feedback for the Swift team as well.
I'm super excited about this! We must steer Ladybird towards memory safety, and the first step is selecting a successor language that we can begin adopting very soon. 🤓🐞

Swift 6 introduced the count(where:) method, enabling more efficient counting of elements in a sequence that meet a condition compared to using a combination of filter() and count.
