Importing autodiff with
import _Differentiation works on the 5.3 release of Swift from here, but not on the default Xcode 12 toolchain, even though at that link it says "Swift 5.3 is available as part of Xcode 12". I realize this is proprietary software I'm asking about, but does anyone have an estimate of when I'll be able to
import _Differentiation with the default Xcode toolchain?
It's just nice to have an obvious and automatically updated toolchain to use when working with a team.
