Proposal Link: swift-evolution/0106-rename-osx-to-macos.md at master · apple/swift-evolution · GitHub
The core team is proactively accepting SE-0106 "Add a macOS Alias for the OSX Platform Configuration Test” without a formal review, under the rationale that the proposal is “obvious” and probably should have been treated as a bug fix. Adding aliases for other uses of “OS X” in the language to use macOS are also proactively accepted.
Thank you Erica Sadun for raising this issue!
