my build phases screenshot

in appdelegate.swift :

    func application(application: uiapplication,     openurl url: nsurl,     sourceapplication: string?,     annotation: anyobject?) -> bool {         return       fbsdkapplicationdelegate.sharedinstance().application(application,             openurl: url,             sourceapplication: sourceapplication,             annotation: annotation) }        func application(application: uiapplication, didfinishlaunchingwithoptions launchoptions: [nsobject: anyobject]?) -> bool {     // override point customization after application launch.     parse.enablelocaldatastore()      // initialize parse.     parse.setapplicationid("",         clientkey: "")      return true } 

in loginviewcontroller have iboulet login button

    var permissions = [ "public_profile", "email", "user_friends" ]      @ibaction func facebooklogin(sender: anyobject) {     pffacebookutils.logininbackgroundwithreadpermissions(permissions,  block: {  (user: pfuser?, error: nserror?) -> void in         if let user = user {             if user.isnew {                 println("user signed , logged in through facebook!")              } else {                 println("user logged in through facebook!")              }         } else {             println("uh oh. user cancelled facebook login.")         }     }) }
