My app uses locationservices for tracking and geofencing in the background.
Now with iOS 13.2 I see every second the following message in the console:
Anchorwatch nehelper sent invalid result code  for Wi-Fi information request
My app does nothing with the WiFi system and when I disable WiFi on the device the message disappears.
While there seem to be no adverse effects by the message I learned the hard way that ignoring message might be a bad idea.
Can anyone hint me to why this message is coming and what I can do to supress it ?
Check out WWDC 19 session 713, It happenes because in iOS13 in order to get WiFi details you should allow location permission, each time you try to pull CNCopyCurrentNetworkInfo data from CNCopySupportedInterfaces array you will get this log.
silly solution may be to try to enable location permission and you will not get this error anymore
It eventually turned out, that a third party framework that my app uses, launches those calls to CNCopyCurrentNetworkInfo.
After I added WiFi access capabilities as described here to the app itself the error message disappeared
