I have implemented Cocoaserver as exampled by Apple. I am now receiving two warning errors on the build: "CocoaEchoServer.m:183: warning: class 'EchoServer' does not implement the 'NSStreamDelegate' protocol".

I have implemented: "- (void)stream:(NSStream *)aStream handleEvent:(NSStreamEvent)streamEvent", which I believe is the correct delegate protocol method from: http://developer.apple.com/mac/library/documentation/cocoa/reference/NSStreamDelegate_Protocol/Reference/Reference.html

With that background, why the warning message?

Read the 10.6 release notes. On 10.6 (i.e. using the 10.6 SDK) delegate methods are generally defined in formal protocols rather than informal protocols as before, which means you have to declare the protocol conformance in the class interface of the delegate. You can also use the 10.5 SDK instead.
