Yup, good catch: looks like we need to add some #if visionOS().

[Lukasa]

Oh actually before even that swift-system needs to.

Let's get apple/swift-system#150 fixed first.

[PushedCrayon]

I actually forked that one just a bit ago and sprinkled in a lot of || os(visionOS) and it worked just fine. This might be a quick easy win

[PushedCrayon]

Looks like apple/swift-system#150 has not been updated for a few years, might have to be something forked and done outside of "official" support

I mean I only filed that ticket two hours ago.
