-/// The type of a test content accessor.
-///
-/// - Parameters:
-///   - outValue: On successful return, initialized to the value of the
-///     represented test content record.
-///   - hint: A hint value whose type and meaning depend on the type of test
-///     record being accessed.
-///
-/// - Returns: Whether or not the test record was initialized at `outValue`. If
-///   this function returns `true`, the caller is responsible for deinitializing
-///   the memory at `outValue` when done.
-typedef bool (* SWTTestContentAccessor)(void *outValue, const void *_Null_unspecified hint);

-/// Resign an accessor function from a test content record.
-///
-/// - Parameters:
-///   - accessor: The accessor function to resign.
-///
-/// - Returns: A resigned copy of `accessor` on platforms that use pointer
-///   authentication, and an exact copy of `accessor` elsewhere.
-///
-/// - Bug: This C function is needed because Apple's pointer authentication
-///   intrinsics are not available in Swift. ([141465242](rdar://141465242))
