these frameworks , libraries have on project:

the weird thing if create new project 0 have no problems @ , login works correctly.

edit: i'm still trying solve issue. managed launch app without errors changing pffacebookutils initialization code from[pffacebookutils initializefacebookwithapplicationlaunchoptions:launchoptions]; [pffacebookutils initialize]; if try login through button code [pffacebookutils logininbackgroundwithreadpermissions:nil block:^(pfuser *user, nserror *error) {}another exception appears terminating app due uncaught exception 'nsinternalinconsistencyexception', reason: 'you must initialize pffacebookutils call +initializefacebookwithapplicationlaunchoptions'

i'm adding code i'm using suggested:

in appdelegate.m

#import <fbsdkcorekit/fbsdkcorekit.h> #import <parsefacebookutilsv4/pffacebookutils.h>  - (bool)application:(uiapplication *)application didfinishlaunchingwithoptions:(nsdictionary *)launchoptions{  // parse [parse setapplicationid: smparseapplicationid               clientkey: smparseclientid];  // facebook [pffacebookutils initializefacebookwithapplicationlaunchoptions:launchoptions];   [pfanalytics trackappopenedwithlaunchoptions:launchoptions]; //*****  // google map api [gmsservices provideapikey: smgoolgemapapikey]; //*****  return [[fbsdkapplicationdelegate sharedinstance] application:application                                 didfinishlaunchingwithoptions:launchoptions]; }  - (bool)application:(uiapplication *)application openurl:(nsurl *)url sourceapplication:(nsstring *)sourceapplication annotation:(id)annotation { return [[fbsdkapplicationdelegate sharedinstance] application:application                                                       openurl:url                                             sourceapplication:sourceapplication                                                    annotation:annotation]; } - (void)applicationdidbecomeactive:(uiapplication *)application {   [fbsdkappevents activateapp]; } 

i've went through same struggle , tried many different ways go setting parse facebook login. have though, have no experience obj-c, here working swift parse w/ facebook login app hope can give insight.

in appdelegate.swift:

func application(application: uiapplication, didfinishlaunchingwithoptions launchoptions: [nsobject : anyobject]?) -> bool {      parse.setapplicationid("id", clientkey:"key")     pffacebookutils.initializefacebookwithapplicationlaunchoptions(launchoptions)     fbsdkprofile.enableupdatesonaccesstokenchange(true)       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) }  func applicationdidbecomeactive(application: uiapplication) {     fbsdkappevents.activateapp() } 

in loginviewcontroller.swift:

//my custom storyboard button     @ibaction func fblogin(sender: anyobject) {      var permissions = ["public_profile", "email"]     pffacebookutils.logininbackgroundwithreadpermissions(permissions) {         (user: pfuser?, error: nserror?) -> void in         if let user = user {             if user.isnew {                 println("user signed , logged in through facebook!")                 self.facebooksignup(user)             } else {                 println("user logged in through facebook!")                 self.performseguewithidentifier("loginsuccessful", sender: self)             }         } else {             println("uh oh. user cancelled facebook login.")         }     } }    override func viewdidload() {     super.viewdidload()      if pfuser.currentuser() != nil {         movetonextview() //segue next viewcontroller     } }   func facebooksignup(user: pfuser) -> void{     var request = fbsdkgraphrequest(graphpath: "me", parameters: nil)     var userid:string      request.startwithcompletionhandler { (connection: fbsdkgraphrequestconnection!, result: anyobject!, error: nserror!) -> void in         if error == nil {             user["fullname"] = result["name"]             var facebookuserid = result["id"] as! string             user["facebookuserid"] = facebookuserid              user.save()             self.performseguewithidentifier("loginsuccessful", sender: self)          } else {             println(error)             pfuser.logout()         }      }  }
