Answer 1

For swift this is the simple way for get the url of the photo with and specific size:

    let params: [NSObject : AnyObject] = ["redirect": false, "height": 800, "width": 800, "type": "large"]
    let pictureRequest = FBSDKGraphRequest(graphPath: "me/picture", parameters: params, HTTPMethod: "GET")
    pictureRequest.startWithCompletionHandler({
        (connection, result, error: NSError!) -> Void in
        if error == nil {
            print("\(result)")


           let dictionary = result as? NSDictionary
           let data = dictionary?.objectForKey("data")
           let urlPic = (data?.objectForKey("url"))! as! String
           print(urlPic)



        } else {
            print("\(error)")
        }
    })

}

@Brandon Gao solution gave me a 200X200 thumbnail... To get a bigger size I used FBSDKProfile to get a path with size, that is also more modular and not hard-coded (although I did have to type in the graph.facebook.com part...)

let size = CGSize(width: 1080, height: 1080)
let path = FBSDKProfile.currentProfile().imagePathForPictureMode(.Normal, size: size)
let url = "https://graph.facebook.com/\(path)"
Alamofire.request(.GET, url, parameters: nil, encoding: ParameterEncoding.URL).response { 
    (request, response, data, error) -> Void in
    if  let imageData = data as? NSData,
        let image = UIImage(data: imageData) {
            self.buttonImage.setImage(image, forState: .Normal)
    }
}

Somehow I didn't get a 1080X1080 image though, FB gave me a 1117X1117... :\

if you want get bigger picture , just replace "type = large" to width=XX&height=XX

but the biggest picture you can get is original picture

FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc] 
                              initWithGraphPath:@"me/picture?width=1080&height=1080&redirect=false" 
                              parameters:nil 
                              HTTPMethod:@"GET"]; 

[request startWithCompletionHandler:^(
                            FBSDKGraphRequestConnection *connection,
                            id result, 
                            NSError *error) { 
if (!error) 
{ 
   NSLog(@"result = %@",result);
   NSDictionary *dictionary = (NSDictionary *)result; 
   NSDictionary *data = [dictionary objectForKey:@"data"]; 
   NSString *photoUrl = (NSString *)[data objectForKey:@"url"]; 
} 
else 
{ 
   NSLog(@"result = %@",[error description]); } 
}];

Thank you @Lyndsey Scott. For Kingfisher, please add enable request http to .plist file.

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
    <key>NSExceptionDomains</key>
    <dict>
        <key>http://graph.facebook.com</key>
        <dict>
            <key>NSExceptionAllowsInsecureHTTPLoads</key>
            <true/>
            <key>NSIncludesSubdomains</key>
            <true/>
        </dict>
    </dict>
</dict>

Then set your user's picture profile to ImageView.

let facebookId = "xxxxxxx"
let facebookProfile: String = "http://graph.facebook.com/\(facebookId)/picture?type=large"
let url: URL = URL(string: facebookProfile)!
myImageView.kf.setImage(with: url)
