Apple is investing a lot in it, but Swift is much younger than Rust (especially as an open source project). There is a working group that meets every few weeks to shepherd the various projects. Most of the recent activity has been (AFAICT) about orchestration. Well, that and transitioning projects to use async/await and structured concurrency. Here's some recent activity in the Swift on server space: - the proposal for distributed actors is currently in-review (https://github.com/apple/swift-evolution/blob/main/proposals...) - a metrics API for backends like Graphite, Prometheus, etc. (https://github.com/apple/swift-metrics) - HTTP/2 support for SwiftNIO (https://github.com/apple/swift-nio-http2) - a new service discovery API (https://github.com/apple/swift-service-discovery) - a new distributed tracing API (https://github.com/appl

e/swift-distributed-tracing) - a Linux implementation of Apple's CryptoKit API on top of BoringSSL (https://github.com/apple/swift-crypto) I'm not pretending that it's taking the server-side world by storm, but there is a fair amount of ongoing activity Personally, I'm using it for a couple personal projects and it's been solid, but I'm already a macOS developer, so it wasn't a big stretch for me to reach for it.

Where is that claimed? There are two paragraphs on the blog that mention secure enclaves or special hardware: your quote, and the following: > With the exception of APIs requiring specialised hardware, it will always be the case that where an Apple CryptoKit implementation of an API is available, Swift Crypto will use it, but when such an API is not available it will be possible to use the Swift Crypto-based implementation. The core APIs will move in step with Apple CryptoKit, and our test suite is shared with Apple CryptoKit ensuring that both projects must pass each other’s test suites for the API, ensuring that both Swift Crypto and Apple CryptoKit will be completely compatible. The SC README[0] contains one more mention of it, with the same general idea: > SwiftCrypto exposes the portions of the CryptoKit API that do not rely on speci

alised hardware to any Swift application. It provides safe APIs that abstract over the complexity of many cryptographic primitives that need to be used in modern applications. These APIs encourage safe usages of the underlying primitives, follow cryptographic best practices, and should be the first choice for building applications that need to use cryptography.
