Summary:
os_activity_t lacks a Swift overlay/apinotes. The work blocking this has already been done in the os headers/compiler for the Dispatch overlay. (With the exception of an OS_OPTIONS macro, see below.) See notes for precise steps.

Steps to Reproduce:
1. Have the desire to use os_activity_t from Swift.
2. Attempt to use os_activity_t from Swift.

Expected Results:
I can use os_activity_t from Swift.

Observed Results:
I cannot.

Version:
Xcode version 9.0 Beta 2 (9M137d) / swiftlang 900.0.45.6

Notes:
- OS_OBJECT_DECL(os_activity) to OS_OBJECT_DECL_CLASS(os_activity)
- os_activity_t made Swift unavailable
- OS_os_activity mapped to OSActivity
- OS_ENUM(os_activity_flag, …) declared as OS_OPTIONS
- OS_OPTIONS declared to use __attribute__((flag_enum)) or added to swift/lib/ClangImporter/ImportEnumInfo.cpp.
- os_activity_flag to OSActivity.Options
- _os_activity_create to OSActivity.init(__dso:description:parent:options:)
- OSActivity.init(_:parent:options:dso:) implemented in overlay
- os_activity_apply to OSActivity.__apply(_:)
- OSActivity.withActive(execute:) implemented in overlay
- os_activity_scope_state_s to OSActivity.Scope
- os_activity_scope_leave to OSActivity.Scope.leave()
- os_activity_scope_enter to OSActivity.enter()
- _os_activity_label_useraction to OSActivity.Type.__labelUserAction(_:dso:)
- OSActivity.Type.labelUserAction(_:dso:) implemented in overlay
- OS_ACTIVITY_NONE to OSActivity.none via __swift_os_activity_none() shim
- Same w/ OS_ACTIVITY_CURRENT
