Hi All,
We have recently implemented the Network API for TLS in lieu of CocoaAsyncSocket, and our connection seems steady for long periods of time, until we start receiving a flood of error messages that I can't find any documentation or evidence for online either in Apple docs or Stack or etc.
Does anyone have any insight into what Network.NWError error 0 entails?
I will include some sample logs below to illustrate just how frequently we are seeing this within a small time frame.
