class NWProtocolFramer

An NWProtocolFramer defines a protocol in a connection's protocol stack that parses and writes messages on top of a transport protocol, such as a TCP stream. A framer can add and parse headers or delimiters around application data to provide a message-oriented abstraction. In order to implement a framer protocol, first define a class that conforms to NWProtocolFramerImplementation. Pass this type to NWProtocolFramer.Definition to create a protocol definition. This can be used to create options with NWProtocolFramer.Options, which can be added to an NWParameters.ProtocolStack. The callbacks and actions for the framer's protocol instance can be set once the NWProtocolFramerImplementation object is intantiated. In order to send and receive framer messages with custom values on an NWConnection, use NWProtocolFramer.Message as part of a NWConnection.ContentContext.
