When you get an error code in with the domain kCFStreamErrorDomainSSL, you can generally find the error codes in SecureTransport.h which is in /System/Library/Frameworks/Security.framework.  Here are the error codes:

enum {
  errSSLProtocol                  = -9800,  /* SSL protocol error */
  errSSLNegotiation               = -9801,  /* Cipher Suite negotiation failure */
  errSSLFatalAlert                = -9802,  /* Fatal alert */
  errSSLWouldBlock                = -9803,  /* I/O would block (not fatal) */
  errSSLSessionNotFound           = -9804,  /* attempt to restore an unknown session */
  errSSLClosedGraceful            = -9805,  /* connection closed gracefully */
  errSSLClosedAbort               = -9806,  /* connection closed via error */
