title: Failed to register for BoringSSL log debug updates
body: <p>When debugging app in Xcode 9 beta while it's running on iPhone with iOS 11 beta installed, I started to notice following messages when performing networking calls:</p>
  
  <pre><code>[] network_config_register_boringssl_log_debug_updates Failed to register for BoringSSL log debug updates
  [BoringSSL] Function boringssl_context_get_peer_npn_data: line 1212 Peer's advertised NPN data is NULL or empty
  </code></pre>
  
  <p>Any idea what is causing this?</p>
