Using NSHost in iOS

Question

I'm trying to make a socket server application in Swift for iOS. I found this great example:

    let addr = "127.0.0.1"
    let port = 4000

    var host :NSHost = NSHost(address: addr)
    var inp :NSInputStream?
    var out :NSOutputStream?

    NSStream.getStreamsToHost(host, port: port, inputStream: &inp, outputStream: &out)

    let inputStream = inp!
    let outputStream = out!
    inputStream.open()
    outputStream.open()

    var readByte :UInt8 = 0
    while inputStream.hasBytesAvailable {
        inputStream.read(&readByte, maxLength: 1)
    }

    // buffer is a UInt8 array containing bytes of the string "Jonathan Yaniv.".
    outputStream.write("Hello", maxLength: "Hello".length)

I tried to run the code in XCode and it said that NSHost didn't exist. I Googled it and I found that NSHost wasn't able for iOS. What can I use instead?

Edit

I'm now using Cocoa Async Socket for socket connections. You can find it here CocoaAsyncScket

You should probably use CFHostRef from CFNetwork and if you wish to do socket communication, I would reference you the tutorial http://www.raywenderlich.com/3932/networking-tutorial-for-ios-how-to-create-a-socket-based-iphone-app-and-server. — Sandeep, Sep 21 '14 at 20:34

Change getStreamsToHost to getStreamsToHostWithName

Change:

NSStream.getStreamsToHost(host, port: port, inputStream: &inp, outputStream: &out)

to

NSStream.getStreamsToHostWithName(addr, port: port, inputStream: &inp, outputStream: &out)

var server = "127.0.0.1"
var port = 4000
//var host :NSHost = NSHost(address: server)
var inp :NSInputStream?
var out :NSOutputStream?
NSStream.getStreamsToHostWithName(server, port: port, inputStream: &inp, outputStream: &out)
let inputStream = inp!
let outputStream = out!
inputStream.open()
defer {
    inputStream.close()
}
outputStream.open()
defer {
    outputStream.close()
}
// do stuff here
