It’s a question about implementing SensorKit Deligate. Currently, you can add entry with all the privileges to get device information.

But why isn’t only the value of didFetchResult that gets the illuminance value called out of the deligate methods.. Other deligate methods are called well (ex device call related method, didCompleteFetch, etc.) Please help

The permissions to the SensorKit are normally received and data can be called, including other Deligate methods and permission settings. Currently, the illumination values that can be shared within the actual device are checked, but the method calling the Deligate illumination value in the code is not called.
