When you bind to a specific port number you always have to have a fallback approach because some other app may be using it. So, what I recommend you do here is simply catch the error and then revert to your fallback. That'll take care of the problem on the simulator but also be helpful in the real world. Regardless of what you do, you should consider advertising your service with Bonjour so that Bonjour-aware clients don't need to hard-code a port number.

Yes. > It doesn’t replace it; it returns a SecTrustRef not an array. As I said, you’ll need to call SecTrustEvaluate afterwards to get the certificate chain. Not necessarily. When you get kCFStreamPropertySSLPeerTrust, it's likely already been evaluated by CFNetwork so you don't need to do it again. You can call SecTrustGetTrustResult() to preflight if SecTrustEvaluate() needs to be called. If it returns kSecTrustResultInvalid in the result parameter, then you need to call SecTrustEvaluate() to build the chain... any other result means the SecTrustRef has already been evaluated and the chain is built. You can then proceed to call SecTrustGetCertificateCount() and SecTrustGetCertificateAtIndex() to obtain each cert in the chain. Protip: calling SecTrustGetCertificateAtIndex(trust, 0) to get the leaf certificate can be done at any time; it doesn't require the trust to be evaluated. -ken > > —Jens -- Sent-From: ☁ @  _______________________________________________ Do not post admin requests to the list.
