facebook friend list

Question

How can i get the list of my friends friends list using new facebook api. i got the friend list using the below code,

$friends = $facebook->api('/uid/friends');

but i am not able to get friend list if i pass their userid in the same function..

Answer 1

You can't, that's their private data so it's under their control. If they then want the application to have access to it, they would grant permission and it can do so on their behalf.

Answer 2

Facebook friend list only fetches a taggable friend list.

Facebook does not access full profiles friend list, it shows only total friend list count in your profile.

pod and plist setting all other should you apply Facebook Developer steps.

So is here my code in Swift 3.0 taggable friend list.

appdelegate.swift

import CoreData
import FBSDKCoreKit
import FBSDKLoginKit
  func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
         return FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
        // Override point for customization after application launch.
        return true
    }
    
    func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {
        return FBSDKApplicationDelegate.sharedInstance().application(app, open: url, options: options)
    }
