swift 3 facebook sdk get friends list

Question

I need to get all my friends list:

I found this code:

var fbRequestFriends: FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "/{friend-list-id}", parameters: [AnyHashable : Any]())

fbRequestFriends.start { (connection, result, error) in
    if error == nil && result != nil {
        print("Request Friends result : \(result!)")
    } else {
        print("Error \(error)")
    }
}

But in return I get this error:

Error Optional(Error Domain=NSURLErrorDomain Code=-1002 "unsupported URL" UserInfo={NSErrorFailingURLStringKey=(null)?access_token=EAAZAaT5Yj9qQBABsXA5KGpwvGX6wIdgX6h9mLtzz6YtgjiOB12XwWxl1MrDJLtZChWSOOKXDiizZCu7uZAixBmqP97HYUXkeg3lkTeeeyjmvhZBOZBibrp2Exa9uZB7V5fflJTvISF2aqK94H7E52svqei6SHvxi3W9vcynSI8hPQBBSawND9NHQif0wYIPuHIpbzl6ErBErvk6nm4ysMo1ZA0BFHVmflVYZD&format=json&include_headers=false&sdk=ios, NSErrorFailingURLKey=(null)?access_token=EAAZAaT5Yj9qQBABsXA5KGpwvGX6wIdgX6h9mLtzz6YtgjiOB12XwWxl1MrDJLtZChWSOOKXDiizZCu7uZAixBmqP97HYUXkeg3lkTeeeyjmvhZBOZBibrp2Exa9uZB7V5fflJTvISF2aqK94H7E52svqei6SHvxi3W9vcynSI8hPQBBSawND9NHQif0wYIPuHIpbzl6ErBErvk6nm4ysMo1ZA0BFHVmflVYZD&format=json&include_headers=false&sdk=ios, NSLocalizedDescription=unsupported URL, NSUnderlyingError=0x7a6285b0 {Error Domain=kCFErrorDomainCFNetwork Code=-1002 "unsupported URL" UserInfo={NSErrorFailingURLKey=(null)?access_token=EAAZAaT5Yj9qQBABsXA5KGpwvGX6wIdgX6h9mLtzz6YtgjiOB12XwWxl1MrDJLtZChWSOOKXDiizZCu7uZAixBmqP97HYUXkeg3lkTeeeyjmvhZBOZBibrp2Exa9uZB7V5fflJTvISF2aqK94H7E52svqei6SHvxi3W9vcynSI8hPQBBSawND9NHQif0wYIPuHIpbzl6ErBErvk6nm4ysMo1ZA0BFHVmflVYZD&format=json&include_headers=false&sdk=ios, NSErrorFailingURLStringKey=(null)?access_token=EAAZAaT5Yj9qQBABsXA5KGpwvGX6wIdgX6h9mLtzz6YtgjiOB12XwWxl1MrDJLtZChWSOOKXDiizZCu7uZAixBmqP97HYUXkeg3lkTeeeyjmvhZBOZBibrp2Exa9uZB7V5fflJTvISF2aqK94H7E52

What are you trying to do? – Magniloquent

do you actually want to get the "friends" or the "friendlists"? there is a difference. btw, you can only get friends who authorized your app too and the api call is /me/friends. – Expertism

/me/friendlists resp. /friendlist-id will only get you info about the list itself anyway (like the list name); it will not give you the users on those lists. – Bandwidth

@luschn How does it know which friends have authorized the app? – Carolynecarolynn

because those are the ones you get with /me/friends. – Expertism

@CBroe is right, this is how the code should look like

let params = ["fields": "id, first_name, last_name, name, email, picture"]

let graphRequest = FBSDKGraphRequest(graphPath: "/me/friends", parameters: params)
let connection = FBSDKGraphRequestConnection()
connection.add(graphRequest, completionHandler: { (connection, result, error) in       
    if error == nil {
        if let userData = result as? [String:Any] {
            print(userData)
        }
    } else {
        print("Error Getting Friends \(error)");
    }

})

connection.start()

{ data = ( ); summary = { "total_count" = 235; }; } . not getting list – Moseley

Bista please tell me why it is not giving the data – Moseley

What is the output? Any Error or message? – Jingo

i found { data = ( ); summary = { "total_count" = 235; }; } – Moseley

It only returns Facebook friends who have also signed up to your app, not the full list. – Impress

@LukeStanyer how does it know which FB friends have signed up to the app? – Carolynecarolynn

FB collects and keeps track of this automatically. Everybody that signs up to your apps gets added to a user list on FB servers and gets assigned a user id unique to your app that will never change. – Impress
