integrate google contacts into ios app (swift)?

Question

So I already have Google SignIn implemented properly - all I want to do now is to sign the user in and grab all of their contacts' information. However, there doesn't really seem to be proper documentation. I know that I have to query https://www.google.com/m8/feeds/contacts/default/full, but I don't know where that query would go or how it would be structured. Any ideas?

This, https://www.google.com/m8/feeds/contacts/default/full, is called an HTTP request. You will send a 'GET' request to the server and if successful, the server sends a response back.

One of many ways to do this is to use XMLHttpRequest in Swift.

snippet:

// Prepare the HTTP request object:
let request = CkoHttpRequest()
request.Path = "/xmlEcho.asp"

// This example will use the "PUT" HTTP request method
// (also known as HTTP verb)
request.HttpVerb = "PUT"
request.ContentType = "text/xml"
request.Charset = "utf-8"
success = request.LoadBodyFromString(xmlStr, charset: "utf-8")

Based on this thread, you can also make use of these methods:

1. Using NSURLSession

   let url = NSURL(string: "http://www.stackoverflow.com")
   
   let task = NSURLSession.sharedSession().dataTaskWithURL(url!) {(data, response, error) in
       print(NSString(data: data!, encoding: NSUTF8StringEncoding))
   }
   
   task.resume()
   

2. Using NSURLConnection

First, initialize an NSURL and an NSURLRequest:

let url = NSURL(string: "http://www.stackoverflow.com")
let request = NSURLRequest(URL: url!)

Then, you can load the request asynchronously with:

NSURLConnection.sendAsynchronousRequest(request, queue: NSOperationQueue.mainQueue()) {(response, data, error) in
print(NSString(data: data!, encoding: NSUTF8StringEncoding))
}

Or you can initialize an NSURLConnection:

let connection = NSURLConnection(request: request, delegate:nil, startImmediately: true)

This is a lot to absorb if it's your first time. Hope this helps.
