 ## Notie in IOS 12.2+
 
-If you are using ios 12.2+, please enable 'Settings > Safari > Motion and Orientation access' and use HTTPS to access
+If you are using ios 12.2+, please enable 'Settings > Safari > Motion and Orientation access' and use HTTPS to access.
+
+Since safari's websocket does not support self-signed certificates, when using HTTPS access, socket.io will probably use XHR instead of websocket, which will increase communication latency.
