(repost) Two comments:
- I’ll specifically call out that I think treating this as an alias rather than a new platform is appropriate - it would be confusing for users if the existing #if os(osx) did not match Sierra. - Do you anticipate a separate proposal deprecating #if os(osx) ? -DW > On Jun 16, 2016, at 8:29 AM, Erica Sadun via swift-evolution > <[email protected]> wrote: > > Starting in Sierra, Apple's Mac-based OS is renamed to macOS. > > All user-facing Swift APIs must go through Swift Evolution.
