You can use Graph API to get different size of images. You need to have picture id. You request it like this:

/{picture-id}?fields=width,height,images

Since above query returns JSON data. In that data "images" contains different sizes.

If the picture you get with <code>picture?type=large</code> is not big enough, I suggest you try with <code>picture?width=9999</code> for example.

The code would be:

<pre><code>let requestPicture = FBSDKGraphRequest(graphPath: "{user_id}/picture?width=9999&amp;redirect=false", parameters: nil, HTTPMethod: "GET")
</code></pre>

If you already have the user's ID and they have given appropriate permissions, you can do:

<pre><code>let imageUrl = NSURL(string: "https://graph.facebook.com/\(userId)/picture?type=large")
 if let data = NSData(contentsOfURL: imageUrl!) {
 let profilePicture = UIImage(data: data)
 }
}
</code></pre>

You can also do any of the enum values: small, normal, album, large, square as explained <a href="https://developers.facebook.com/docs/graph-api/reference/user/picture/" rel="nofollow">here</a>. Better yet, you can use AFNetworking to load the image in the background with a placeholder image, which handles caching and everything for you. See <a href="https://github.com/AFNetworking/AFNetworking/blob/master/UIKit%2BAFNetworking/UIImageView%2BAFNetworking.h" rel="nofollow">here</a> for more details, specifically setImageWithURL.

From the login or by making the basic graph request with me you can get user-id and from that user-id you may try this 

You can try like this:

<pre><code>let fbRequest = FBSDKGraphRequest(graphPath:"/{user-id}/picture?redirect=false&amp;type=large", parameters: nil);
 fbRequest.startWithCompletionHandler { (connection : FBSDKGraphRequestConnection!, result : AnyObject!, error : NSError!) -&gt; Void in
 if error == nil {

 print("Result is : \(result)")
 /* this will return the data of the image which you can use with imageview with data method {
 "data": "ProfilePictureSource",
 "paging": {}
 }*/

 } else {

 println("Error Getting Friends \(error)");

 }
 }
</code></pre>

For the fields which you have pass <code>picture.height and picture.width</code> is used to specify the image with which is return to you in the response 

You can use both types of size reference :

Predefined sizes: small, normal, large, square. 
Custom size: specify the width and height of the image you want 

For more information you can check the facebook doc : <a href="https://developers.facebook.com/docs/graph-api/reference/user/picture://" rel="nofollow">Facebook doc:User Profile</a>

I have tried several ways to get larger images from Facebook Graph API, but I have not succeeded. 

<ol>
<li>I don't really know how this Parameters work. So will you explain me that too?</li>
<li>Also I need to know how to grab the larger images. 
I first get the album I'd and then pictures ID and then I fetch the image of the album. </li>
<li>What is the best picture size to get for iPhone 6?

<pre><code>let parameters = ["fields": "picture.height(400).width(200)"]
FBSDKGraphRequest(graphPath: "/{picture-id}", parameters: parametes, HTTPMethod: "GET")
</code></pre></li>
</ol>
