I have to create an application (in Swift) which fetch informations from a server. They can change at any moment and I want my app to be always up to date.
Here is an instance to be sure you understand the problem : there is an temperature sensor which continually calculate the current temperature. Here my application displays it. And I want the server to notified the application that the temperature had changed right now. Thereby the application gets the new value and displays it.
My question : What's the best kind of server should I use for that ? I already used web socket for that kind of use but I'm not sure it's the best way to do that...
Thanks in advance :D
