Hey,
I am developing a multiplayer game that would require the game to communicate with backend servers(written in Python) through WebSockets. I am not aware of any plugin that would allow me to use WebSocket for iOS in Unreal.
I meet this problem too…
there is a class FSocket able to manage that stuff easily for you, here the example A new, community-hosted Unreal Engine Wiki - Announcements and Releases - Unreal Engine Forums,Receive_Binary_Data_From_an_IP/Port_Into_UE4,(Full_Code_Sample)
