Answer 1

In Graph API v2.0 or above, calling /me/friends returns the person's friends who installed the same apps. Additionally, you must request the user_friends permission from each user. user_friends is no longer included by default in every login. Each user must grant the user_friends permission in order to appear in the response to /me/friends.

To get the list of friends who are using your app use following code:

    let params = ["fields": "id, first_name, last_name, middle_name, name, email, picture"]
    let request = FBSDKGraphRequest(graphPath: "me/friends", parameters: params)
    request.startWithCompletionHandler { (connection : FBSDKGraphRequestConnection!, result : AnyObject!, error : NSError!) -> Void in

        if error != nil {
            let errorMessage = error.localizedDescription 
            /* Handle error */
        }
        else if result.isKindOfClass(NSDictionary){
            /*  handle response */
        }
    }

If you want to access a list of non-app-using friends, then use following code:

    let params = ["fields": "id, first_name, last_name, middle_name, name, email, picture"]
    let request = FBSDKGraphRequest(graphPath: "me/taggable_friends", parameters: params)
    request.startWithCompletionHandler { (connection : FBSDKGraphRequestConnection!, result : AnyObject!, error : NSError!) -> Void in

        if error != nil {
            let errorMessage = error.localizedDescription 
        }
        else if result.isKindOfClass(NSDictionary){    
            /* Handle response */
        }
    }

graphPath: "me/friends fetching only count of friends – Gleiwitz

@Himanshu Mahajan, I tried your two codes but I'm not getting friends list. This is my response is : success(response: FacebookCore.GraphResponse(rawResponse: Optional({ data = ( ); }))) . When i use "me/friends" I'm getting only count. – Ain

@Himanshu Mahajan Ae you got the list?, if yes. Please help me... Thank you. – Ain

Does this GraphAPI return the email id of friends? – Viand

Answer 2

For fetching the friend list must allow user permission user_friends at the time of login. For swift 3.0 add below code for fetching friend list:

let params = ["fields": "id, first_name, last_name, middle_name, name, email, picture"]
    FBSDKGraphRequest(graphPath: "me/taggable_friends", parameters: params).start { (connection, result , error) -> Void in

        if error != nil {
            print(error!)
        }
        else {
            print(result!)
            //Do further work with response
        }
    }

I hope it works!

Remember only those friends are fetched who are using your app and u should have taken users read permission for user_friends while logging.

var fbRequest = FBSDKGraphRequest(graphPath:"/me/friends", parameters: nil);
            fbRequest.startWithCompletionHandler { (connection : FBSDKGraphRequestConnection!, result : AnyObject!, error : NSError!) -> Void in

                if error == nil {

                    println("Friends are : \(result)")

                } else {

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

                }
            }

Is there a way to see "all friends" including those who have not installed the same app? – Armoury

@VanDuTran i don't think so that u would be able to get all the friends. From new SDK u are able to get only those friends who have installed the app. – Langlauf

Just making an union here that solved my problems:

From Dheeraj Singh, to get friends using your app:

var request = FBSDKGraphRequest(graphPath:"/me/friends", parameters: nil);

request.startWithCompletionHandler { (connection : FBSDKGraphRequestConnection!, result : AnyObject!, error : NSError!) -> Void in
    if error == nil {
        println("Friends are : \(result)")
    } else {
        println("Error Getting Friends \(error)");
    }
}

And to get all facebook friends, from Meghs Dhameliya, ported to swift:

var request = FBSDKGraphRequest(graphPath:"/me/taggable_friends", parameters: nil);

request.startWithCompletionHandler { (connection : FBSDKGraphRequestConnection!, result : AnyObject!, error : NSError!) -> Void in
    if error == nil {
        println("Friends are : \(result)")
    } else {
        println("Error Getting Friends \(error)");
    }
}

I need all friends but taggable_friends return a extrange id different to facebookId – Cierracig

Answer 5

you can get friend list using taggable_friends Graph API Reference for User Taggable Friend

  /* make the API call */
    [FBRequestConnection startWithGraphPath:@"/me/taggable_friends"
                          completionHandler:^(
                              FBRequestConnection *connection,
                              id result,
                              NSError *error
                          ) {
                              /* handle the result */
                          }];

Swift - 4
This will only return your facebook friends using the same app.

// First you have to check that `user_friends` has associated with your `Access Token`, If you are getting false, please allow allow this field while you login through facebook.
if FBSDKAccessToken.current().hasGranted("user_friends") {

        // Prepare your request
        let request = FBSDKGraphRequest.init(graphPath: "me/friends", parameters: params, httpMethod: "GET")

        // Make a call using request
        let _ = request?.start(completionHandler: { (connection, result, error) in
              print("Friends Result: \(String(describing: result))")
        })
}

Answer 7

With user_friends permission you can have access to the list of your friends that also use your app, so if your app is not used by any of your friend, the list will be empty. See user_friends permission reference
