Firebase simple login in iOS - ios

Question

I am using FirebaseSimpleLogin for authenticating my app via facebook.
I have updated .plist file with facebookapp id and display name. I have also registered bundle id of my app.
As suggested in docs, i have also implemented openUrl in AppDelegate and following method in my login with Facebook button. But console is showing third party provider error occurred. Anyone have any clue??
- ( IBAction ) onBtnFacebook : ( id ) sender {
[self.authClient loginToFacebookAppWithId:#"767056019984823" permissions:#[#"email"] audience:ACFacebookAudienceOnlyMe withCompletionBlock:^(NSError *error, FAUser *user) {
if (error != nil) {
NSLog(#"%#",error);
UIAlertView *message = [[UIAlertView alloc] initWithTitle:#""
message:#"There was an error in opening your account. Please try again."
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[message show];
} else {
UIAlertView *message = [[UIAlertView alloc] initWithTitle:#"Welcome"
message:self.email
delegate:nil
cancelButtonTitle:#""
otherButtonTitles:nil];
[message show];
[ self dismissViewControllerAnimated : YES completion : ^{
} ] ;
}
}];
}
In Appdelegate.m
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {
BOOL wasHandled = [FBAppCall handleOpenURL:url sourceApplication:sourceApplication];
NSLog(#"hello");
// add any app-specific handling code here
return wasHandled;
}
