USE user_id to fetch friends.It is working fine . Try it

-(void)fetchFriendList:(NSString*)userid
{

    NSString *string = [NSString stringWithFormat:@"/%@/taggable_friends",userid];

    FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc]
                                  initWithGraphPath:string
                                  parameters:nil];
    [request startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection,
                                          id result,
                                          NSError *error) {

    ///// your results
    }];
