title: Swift Socket server
body: <p>I'm pretty new to programming. Especially to swift. I have many questions. One of them is: How to create a socket server, I think it's called so. Like in minecraft pocket edition or terraria. When you create a server the other person needs to be on the same Wi-Fi. Does someone know how to do that? Is it even called socket? If someone have a Swift source code that let's multiple iPhone's send a string to one iPhone. If the one phone can send back a string or some thing that would be great!</p>
  
  <p>Thanks in advance!
