Currently i am working on one app and it's include call directory extension and when i am trying to reload call directory extension i am getting
error: Error Domain=com.apple.CallKit.error.calldirectorymanager Code=102 "(null)"
and as per the apple documentation apple didn't mention about this error code.
https://developer.apple.com/documentation/callkit/cxerrorcodecalldirectorymanagererror/code
That is an internal error indicating that the extension is unavailable. It can be that your call directory extension wasn't enabled in Settings.app, or the system failed to load your extension. In the latter case, you might capture a sysdiagnose and look into it to hopefully find a hint that indicates the reason of the failure.
Best,
