Objc C in Swift implementieren

[Softis]

Hallo Leute,

ich bin noch ziemlich am Anfang mit dem iOS Development aber stehe jetzt entgültig vor einem Problem wo ich nicht mehr weiter weiß.
Ich habe nun eine App mit Facebook Login programmiert in C, und einen Parse Login in Swift.
Ich möchte nun gerne in Swift weiterarbeiten, bräuchte aber die Logindaten vom Facebookuser dafür im Swift Code.
Aus der Doku von Apple und anderen Seiten im www werde ich auch nicht schlau, bis auf die Sache mit dem Bridging Header.
Vielleicht könnt ihr mir weiterhelfen, wäre sehr nett.

Ich bräuchte in Swift nur den "name, email, fbid, facebookurl" zu wiedergeben.

Das ist der Code in C, von denen ich die Daten haben möchte.

//  LoginViewController.m
//  facebookLogin

#import "LoginViewController.h"
#import <FBSDKCoreKit/FBSDKCoreKit.h>
#import <FBSDKLoginKit/FBSDKLoginKit.h>
#import "DashboardViewController.h"
#import "MBProgressHUD.h"

@interface LoginViewController (){

    /*!
     *properties of name, email,fbid and fburl.
     */
    NSString* name;
    NSString* email;
    NSString* fbid;
    NSURL *facebookurl;
    }

@end

@implementation LoginViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view.
}

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}
/*!
*Fb signin button clicked.
*/
- (IBAction)facebookLoginClicked:(id)sender {
//saving the login method inorder to swap the main screen when the app goes background...
    [[NSUserDefaults standardUserDefaults]setObject:@"facebookSuccess" forKey:@"loginSuccess"];
    [[NSUserDefaults standardUserDefaults]synchronize];
//FBSDKLoginManager in order to read permission with the viewcontroller..
        FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
        [login logInWithReadPermissions:@[@"email", @"user_friends", @"public_profile"] fromViewController:self handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {
           
             if (error) {
                 NSLog(@"Process error");
             } else if (result.isCancelled) {
                 NSLog(@"Cancelled");
             }
//On success case, the granted permission access will be email...
             else {
                 if ([result.grantedPermissions containsObject:@"email"])
                 {
                     NSLog(@"Logged in");
                     NSLog(@"result is:%@",result);
                     [self fetchedUser];
                 }
             }
         }];

}
/*!
*This contains details of the fetched user details.

-(void)fetchedUser{
    NSLog(@"the user token is :%@", [FBSDKAccessToken currentAccessToken]);
   
    //Checking for the usertoken of the current user is not null or nill...
   
    if ([FBSDKAccessToken currentAccessToken] != nil && ![[FBSDKAccessToken currentAccessToken]  isEqual: @"null"])
    {
        [[[FBSDKGraphRequest alloc] initWithGraphPath:@"me" parameters:@{@"fields": @"id, name, link, first_name, last_name, picture.type(large), email, birthday, bio ,location ,friends ,hometown , friendlists"}]
         startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
             if (!error)
             {
//Fetching the user details and saving it in the properties...
                 name = result[@"name"];

                 [[NSUserDefaults standardUserDefaults]setObject:name forKey:@"name"];

                 [[NSUserDefaults standardUserDefaults]synchronize];
                 [[NSUserDefaults standardUserDefaults]setObject:[facebookurl absoluteString] forKey:@"facebookurl"];
                 [[NSUserDefaults standardUserDefaults]synchronize];
                 
//performing a segue to the dashboard view.
                 [MBProgressHUD showHUDAddedTo:self.view animated:YES];
                 [self performSegueWithIdentifier:@"facebookSuccess" sender:self];
                 [MBProgressHUD hideHUDForView:self.view animated:YES];
             }
             else
             {
                 NSLog(@"Error %@",error);
             }
         }];
       
    }
