8 months ago Thanks for reporting @alicerunsonfedora . Unfortunately this is one case where we rely on Swift features that are not in the Swift 5.9 or 5.10 builds. This project requires more recent Swift toolchain builds. See this note in our Readme.
https://github.com/tristanlabelle/swift-winrt is an independent implementation I'm working on. It doesn't have this specific problem, but it is different in many other ways and less battle-tested.
