NEAppProxyTCPFlow - Detect connection close

From the documentation, when the NEAppProxyTCPFlow.readData returned data with length 0, no more can be subsequently read from the flow. In this situation, can I assume the flow is closed and proceed to close the flow? Or should I wait for more data coming in to handle NEAppProxyTCPFlow.write?

One approach to this would be to use NWConnection on the remote side of the proxy and when a flag for isComplete is send on the receive method, then it would be time to tear down the remote connection and the NEAppProxyTCPFlow side as well.
