Answer 1

I've used fields in android, so I figured to try it in iOS as well, and it works.

let req = FBSDKGraphRequest(graphPath: "me", parameters: ["fields":"email,name"], tokenString: accessToken.tokenString, version: nil, HTTPMethod: "GET")
   req.startWithCompletionHandler({ (connection, result, error : NSError!) -> Void in
       if(error == nil) {
            print("result \(result)")
       } else {
            print("error \(error)")
       }
   }
)

result will print:

result {
   email = "email@example.com";
   id = 123456789;
   name = "Your Name";
}

Found that these fields are equal to the User endpoint, see this link where you can see all the fields that you can get.

Update for Swift 4 and above

let r = FBSDKGraphRequest(graphPath: "me",
                          parameters: ["fields": "email,name"],
                          tokenString: FBSDKAccessToken.current()?.tokenString,
                          version: nil,
                          httpMethod: "GET")

r?.start(completionHandler: { test, result, error in
    if error == nil {
        print(result)
    }
})

Update for Swift 5 with FBSDKLoginKit 6.5.0

guard let accessToken = FBSDKLoginKit.AccessToken.current else { return }
let graphRequest = FBSDKLoginKit.GraphRequest(graphPath: "me",
                                              parameters: ["fields": "email, name"],
                                              tokenString: accessToken.tokenString,
                                              version: nil,
                                              httpMethod: .get)
graphRequest.start { (connection, result, error) -> Void in
    if error == nil {
        print("result \(result)")
    }
    else {
        print("error \(error)")
    }
}
