I’d also like to know the answer to this.
If you are building with older tools then you could try creating a small test
project with the latest Xcode to see how that behaves.

`errSSLClosedAbort` indicates that the server gracefully closed the connection.
It’s hard to tell why it did that, but the next step is to use a packet trace
to see how far things got during the handshake progress. If this is a TLS
version problem you’ll see the client send a Client Hello with a max TLS
version of 1.0, to which the server will respond by closing the connection.
See QA1176 “Getting a Packet Trace” for more about packet traces.
