Gets the type identifier for Search Kit summarization objects.
- macOS 10.4+
- Core Services
A CFTypeID object, or
NULL on failure.
Search Kit represents summarization results with summarization objects (
SKSummary opaque types). If your code needs to determine whether a particular data type is a summary, you can use this function along with the
CFGet function and perform a comparison.
Never hard-code the summarization type ID because it can change from one release of macOS to another.
