This post describes the release process, and estimated schedule for Swift 5.10.
Downloadable snapshots of the Swift 5.10 release branch will be posted regularly as part of continuous integration testing. As support is available, snapshot downloads will be added for newly supported platforms.
Once Swift 5.10 is released, the official final builds will also be posted in addition to the snapshots.
On September 6th the
release/5.10 branch will be cut from
main in the swift repository and related project repositories. This will contain the changes that will be released in Swift 5.10. After the branch is cut, changes can be landed on the branch via pull request if they meet the criteria for the release.
- All language and API changes for Swift 5.10 will go through the Swift Evolution process. Evolution proposals should aim to be completed by the branch date in order to increase their chances of impacting the Swift 5.10 release. Exceptions will be considered on a case-by-case basis, particularly if they tie in with the core goal of the release.
- Other changes (e.g., bug fixes, diagnostic improvements, SourceKit interface improvements) will be accepted based on their risk and impact.
- Low-risk test tweaks will also be accepted late into the release branch if it aids in the qualification of the release.
- As the release converges, the criteria for accepted changes will become increasingly restrictive.
The following repositories will have a
release/5.10 branch to track
sources as part of Swift 5.10 release:

- Scope: An assessment of the impact/importance of the change. For example, is the change a source-breaking language change, etc.
- Issue: The GitHub Issue link if the change fixes/implements an issue/enhancement
- Risk: What is the (specific) risk to the release for taking this change?
- Testing: What specific testing has been done or needs to be done to further validate any impact of this change?
- Reviewer: One or more code owners for the impacted components should review the change. Technical review can be delegated by a code owner or otherwise requested as deemed appropriate or useful.
