There is an updated pull request by Derriick against master on the void-packages repository

https://github.com/Derriick/void-packages sway
https://github.com/void-linux/void-packages/pull/11476

sway: update to 1.1+rc1.
This is a release candidate, but package maintainers have not been instructed not to package this release as the developers did for the old ones.
It is up to you to decide if you want to add this version to void repositories (if the template is correct) or not ;)

A patch file from https://github.com/void-linux/void-packages/pull/11476.patch is attached
