title: Checking IP Address Reachability using SWIFT
body: <p>I'm trying to check if a Host is available in Swift, I am using Apple's Reachability, but I can't get it to work giving it an IP Address and Port, I think my problem is that this requires a struct for the address or something, can somebody please explain / lead me into the right way to do this?</p>
  
  <p>Thanks!</p>
