Question: why are @available directives commented out? about swift-system

[milseman]

This is due to language/tooling issues. We'd like the ability to add availability based on conditional compilation for ABI-stable builds of Swift System while not adding availability for package builds (i.e. a source dependency). For now, we include, but comment out, the availability declarations matching what has already been shipped in binary releases.

Would it help to add an explanation to it somewhere, either in comment(s) or in the documentation?

[milseman]

@BasThomas definitely. I'm trying to put together some more extensive documentation and this should be part of that.

[milseman]

I put this in the new FAQ issue: #18

I’d guess System was supposed to be included in those versions of the OSes, but then they decided to make it an open source Swift Package, compatible with Linux

@Snowy1803 Note that System is included in those versions of the OSes (https://developer.apple.com/documentation/system).

Great!
