I have an SCStreamDelegate for capturing frames from applications. On recent point releases of macOS Sonoma, I've noticed that the stream is being cancelled with no user action being taken. I started trying to debug it and when my on error method is called, the error parameter being passed is null:
func stream(_ stream: SCStream, didStopWithError error: Error) {
/*debugger shows this and segfaults if I try to print "\(error)"
error (Error)
> error = (Builtin.RawPointer) 0x0
*/
From what I can tell, error should be a valid NSError so I can check the error code, based on similar code I've seen in, for example OBS (https://github.com/obsproject/obs-studio/blob/265239d4174f8d291b0de437088c5b78f8e27687/plugins/mac-capture/mac-sck-common.m#L29)
Usually when this happens, the menubar icon for screen sharing (where I would click to change sharing window, etc) stays there even after my app has closed an no apps are doing sharing stuff.
Has anyone come across this before? Am I misinterpreting what the debugger is saying about the error parameter?
I'm running macos 14.7.3, but I just updated from 14.7.2 earlier and had basically the same issue on both macos versions
