- have public visibility - have at most one back deployment version per-platform - specify an introduced version for each platform with a back deployment version using @available - have a back deployment version that is greater than the introduced version - not have conflicting attributes like @_alwaysEmitIntoClient Refactor to share code with type checking for @_originallyDefinedIn which has overlapping diagnostics.
