SwiftWasm 5.8.0 is now available

We're happy to announce the new release of SwiftWasm tracking upstream Swift 5.8!

Notable WebAssembly-specific changes in this release:

  • The toolchain is now available for Ubuntu 22.04 on the x86_64 architecture. (Note that aarch64 support is available only for macOS and Ubuntu 20.04 for now.)
  • Support for Distributed Actors on WebAssembly was added.
  • The ghcr.io/swiftwasm/swift Docker image is now based on Ubuntu 22.04 by default for latest and 5.8 tags.

As for changes in upstream Swift 5.8, we recommend referring to the official changelog.

For more information about SwiftWasm in general and for getting started, please visit the project documentation. If you have any questions, please come and talk to us on the SwiftWasm discussion forums or open an issue!


We'd like to thank our GitHub sponsors and OpenCollective contributors for their support, which allowed us to continue working on SwiftWasm and related projects.

We're committed to publishing transparent and open finances, so all expenses and transactions can be viewed publicly on our OpenCollective Transactions page.

So far we've spent money on monthly CI bills that cover new aarch64 CPU architecture and community CI, domain registration, email hosting, and development hardware for our maintainers.

Many thanks to MacStadium for giving us access to Apple Silicon hardware.

Additionally, we'd like to thank everyone who contributed their work and helped us make this release happen. These new releases wouldn't be possible without the hard work of them and the Swift community as a whole.
