We finally have the [Xcode 12.5 RC](https://developer.apple.com/documentation/xcode-release-notes/xcode-12_5-release-notes#Swift), and it has some notable Swift language fixes and improvements.

In the last two weeks seems that the Swift core team has woken up after winter sleep. Now dozens of proposals are in review and more returned.
