ios - Parse: Facebook login not creating new PFUser -

i've been trying integrate facebook login , parse, new pfuser created upon logging in. have created facebook login button, , when press standard facebook login/asking permissions screen appears. when accept login redirected initial screen, , log shows user has cancelled facebook login. when check data on parse website, there no pfusers.

as far can tell have followed exact instructions laid out parse (https://parse.com/docs/ios/guide#users) , facebook.(https://developers.facebook.com/docs/ios/getting-started). using xcode 6.3.2. have added integrated parse (parsefacebookutilsv4 v1.7 & parseui v1.1) , facebook (fbsdkcorekit v4.2 &fbsdkloginkit v4.2) in cocoapods, , have linked following libraries:

libsqlite3.dylib libz.dylib accounts.framework audiotoolbox.framework cfnetwork.framework coregraphics.framework corelocation.framework corelocation.framework mobilecoreservice.framework quartzcore.framework security.framework social.framework storekit.framework systemconfiguration.framework libpods-xxx.a (being name of project) 

my code follows:

//appdelegate.swift import uikit   @uiapplicationmain class appdelegate: uiresponder, uiapplicationdelegate {  var window: uiwindow?  //-------------------------------------- // mark: - uiapplicationdelegate //--------------------------------------  func application(application: uiapplication, didfinishlaunchingwithoptions   launchoptions: [nsobject: anyobject]?) -> bool {       parse.setapplicationid("xxxxxxxx",         clientkey: "xxxxxxxxxx")                pffacebookutils.initializefacebookwithapplicationlaunchoptions(launchoptions)      return fbsdkapplicationdelegate.sharedinstance().application(application, didfinishlaunchingwithoptions: launchoptions)   }  }   func application(   application: uiapplication,                 openurl url: nsurl,                 sourceapplication: string,                 annotation: anyobject?) -> bool { return fbsdkapplicationdelegate.sharedinstance().application(application,                                                             openurl: url,                                                             sourceapplication: sourceapplication,                                                             annotation: annotation) }  //facebook analytics func applicationdidbecomeactive(application: uiapplication!) { fbsdkappevents.activateapp() }  

and view controller in login in placed:

//onboardingrootviewcontroller.swift  import foundation import uikit     class onboardingrootviewcontroller: uiviewcontroller {   override func viewdidload() {     super.viewdidload() }   override func didreceivememorywarning() {     super.didreceivememorywarning()     // dispose of resources can recreated. }    @ibaction func fbloginclick(sender: anyobject) {  var permissions = ["public_profile", "email", "user_likes"]   pffacebookutils.logininbackgroundwithreadpermissions(permissions) {     (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.")     } } }   } 

so, can of help? again, facebook login @ least appears work, when ibaction fbloginclick invoked, "uh oh. user cancelled facebook login." message shown in log, , no new pfuser created in parse. i've seen multiple other similar questions, none real answers i'm sure answer question appreciated many, using exact code shown in login tutorials created parse , facebook!

edit: if no 1 able help, i'd still appreciate following: i've been told should check error message returned logininbackgroundwithreadpermissions, unfortunately without further explanation. person referring "uh oh. user cancelled facebook login." message, or possible retrieve information through nserror?

edit #2: added following line of code see nserror returns: println("write failure: (error?.localizeddescription)")

and following message in log: uh oh. user cancelled facebook login. write failure: nil

so guess didn't me further...

edit #3: seriously, i'll paypal 10$ can me

this code work if set frameworks correctly , follow steps of parse's facebook setup guide (https://parse.com/docs/ios/guide#users-facebook-users). make sure syntax same functions have , try getting rid of unnecessary code isn't included below.

appdelegate.swift

import uikit import coredata import parse  @uiapplicationmain class appdelegate: uiresponder, uiapplicationdelegate {  var window: uiwindow?  func application(application: uiapplication, didfinishlaunchingwithoptions launchoptions: [nsobject: anyobject]?) -> bool {      //x's replace actual parse information      parse.setapplicationid("xxxxxxxxxxxxxxxxxxxxxx", clientkey: "xxxxxxxxxxxxxxxxxxxxxx")     pfanalytics.trackappopenedwithlaunchoptions(launchoptions)      pffacebookutils.initializefacebookwithapplicationlaunchoptions(launchoptions)      return fbsdkapplicationdelegate.sharedinstance().application(application, didfinishlaunchingwithoptions: launchoptions)  }  func applicationwillresignactive(application: uiapplication) {     // sent when application move active inactive state. can occur types of temporary interruptions (such incoming phone call or sms message) or when user quits application , begins transition background state.     // use method pause ongoing tasks, disable timers, , throttle down opengl es frame rates. games should use method pause game. }  func applicationdidenterbackground(application: uiapplication) {     // use method release shared resources, save user data, invalidate timers, , store enough application state information restore application current state in case terminated later.     // if application supports background execution, method called instead of applicationwillterminate: when user quits. }  func applicationwillenterforeground(application: uiapplication) {     // called part of transition background inactive state; here can undo many of changes made on entering background. }  func applicationdidbecomeactive(application: uiapplication) {      fbsdkappevents.activateapp() }  /* func application(application: uiapplication, url: nsurl, sourceapplication: nsstring, annotation: anyobject) -> bool {      return fbsdkapplicationdelegate.sharedinstance().application(         application,         openurl: url,         sourceapplication: sourceapplication string,         annotation: annotation)  }*/  func application(application: uiapplication,     openurl url: nsurl,     sourceapplication: string?,     annotation: anyobject?) -> bool {         return fbsdkapplicationdelegate.sharedinstance().application(application,             openurl: url,             sourceapplication: sourceapplication,             annotation: annotation) }  func applicationwillterminate(application: uiapplication) {     // called when application terminate. save data if appropriate. see applicationdidenterbackground:.     // saves changes in application's managed object context before application terminates.     self.savecontext() } 

viewcontroller.swift

import uikit  class viewcontroller: uiviewcontroller {  override func viewdidload() {     super.viewdidload()     // additional setup after loading view, typically nib. }  override func didreceivememorywarning() {     super.didreceivememorywarning()     // dispose of resources can recreated. }  let permissions = [ "email","user_birthday", "public_profile", "user_friends"]  @ibaction func loginbuttonpressed(sender: anyobject) {     pffacebookutils.logininbackgroundwithreadpermissions(permissions) {         (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.")         }     } }  } 

the @ibaction simple uibutton put in center of blank viewcontroller in main.storyboard

objective-c bridging header:

#import <fbsdkcorekit/fbsdkcorekit.h> #import <parsefacebookutilsv4/pffacebookutils.h> #import <parse/parse.h> 

hope solves problem!
