How to retrieve user mail and name? (PFFacebookUtils.logInInBackgroundWithReadPermissions, swift 1.2) - facebook

Question

I have successfully logged my user in, using the following code and plenty of reading on stackoverflow:
#IBAction func FBlogin(sender: UIButton) {
self.activity.startAnimating()
let permissions = ["public_profile", "email"]
PFFacebookUtils.logInInBackgroundWithReadPermissions(permissions) {
(user: PFUser?, error: NSError?) -> Void in
if let user = user {
self.activity.stopAnimating()
if user.isNew {
print(user.email)
print(user.username)
print("User signed up and logged in through Facebook!")
} else {
print(user.email)
print(user.username)
print("User logged in through Facebook!")
}
} else {
self.activity.stopAnimating()
}
}
}
This creates a new user in parse.com BUT does not fill-in email, username ...?
QUESTION: how does one retrieve the email and userName details?
AFTER searching and fiddling more I added this code:
func getUserDataFromFacebookProfile(user: PFUser)
{
var facebookid : String?
var username : String?
var userEmail : String?
var userGender : String?
var userLocation : String?
let graphRequest : FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "me", parameters: nil)
graphRequest.startWithCompletionHandler({ (connection, result, error) -> Void in
if ((error) != nil)
{
// Process error
print("graphrequest error: \(error)")
}
else
{
//if this works, we can store user name und PFUser and mail in PFuser....
//not working yet
/*
id
name
first_name
last_name
link
gender
locale
timezone
updated_time
verified
*/
facebookid = result.valueForKey("id") as? String
userEmail = result.valueForKey("email") as? String
username = result.valueForKey("name") as? String
let fname = result.valueForKey("first_name") as? String
let lname = result.valueForKey("last_name") as? String
let loc = result.valueForKey("locale") as? String
let gend = result.valueForKey("gender") as? String
//userGender = result.valueForKey("gender") as? String
userLocation = result.valueForKey("location") as? String
print("*****************************************************************************")
print("")
print("graphrequest result \(facebookid), \(username), \(userEmail), \(gend), \(fname), \(lname)")
print("")
print("*****************************************************************************")
}
//persist in our DB for later
let thisUser: PFUser = user
print("updating current user")
if let uName = username {
thisUser.username = uName
}
if let uEmail = userEmail {
thisUser.email = uEmail
}
thisUser.saveInBackground()
})
}
The strange thing is that I can only retrieve id, email and name?!

About email: Search for "Declarative Fields" in the changelog: https://developers.facebook.com/docs/apps/changelog#v2_4
About username: That field is no longer available since v2.0 of the Graph API: https://developers.facebook.com/docs/apps/changelog#v2_0

So here is what worked for me. Appparently FB has again changed a few things. The key is to add the required fields to the parameter list, like so:
let graphRequest : FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "email,first_name,last_name,gender,picture.width(480).height(480)"])
