Swift 5.3 is nearing completion, and has been updated with the extension of official platform support to include Windows, along with additional Linux distributions.
Swift 5.3 is a release meant to include significant quality and performance enhancements.
One improvement to the new release is the addition of several new Swift Linux distributions, including Ubuntu 20.04, CentOS 8, and Amazon Linux 2.
New distributions are provided with a downloadable toolchain and Docker images. The support for Windows does not go as far as providing a Windows port of the Swift UI client, nor does it seem to be based on the open source Swift for Windows project. Instead, the Swift compiler will support Windows as a target.
Discussing the new release, the Swift team says:
“We are likely to see a succession of Swift 5.x releases — each which will make progress on the frontiers outlined above — as we build up towards Swift 6. Each of those releases will be a major release in their own right. What will differentiate Swift 6 from the Swift 5.x releases will be a significant change in the capabilities of the language. At this point, that change is improved concurrency support, and further progress towards the memory ownership model.”Swift team
