Swift + Take pictures and save to camera roll using UIImagePickerController

First Add and Import MobileCoreServices Framework.

Confirm to UIImagePickerControllerDelegate & UINavigationControllerDelegate protocol

import UIKit

import MobileCoreServices

class ViewController: UIViewController, UIImagePickerControllerDelegate, UIAlertViewDelegate, UINavigationControllerDelegate

{

    var cameraUI: UIImagePickerController! = UIImagePickerController()

    

    

    override func viewDidLoad()

    {

        super.viewDidLoad()

    }

    override func didReceiveMemoryWarning()

    {

        super.didReceiveMemoryWarning()

        

    }

    //--- Take Photo from Camera ---//

    @IBAction func takePhotoFromCamera(sender: AnyObject)

    {

          self.presentCamera()

    }

    func presentCamera()

    {

       

        if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.Camera)

        {

            println("Button capture")

        

            cameraUI = UIImagePickerController()

            cameraUI.delegate = self

            cameraUI.sourceType = UIImagePickerControllerSourceType.Camera;

            cameraUI.mediaTypes = [kUTTypeImage]

            cameraUI.allowsEditing = false

            

            self.presentViewController(cameraUI, animated: true, completion: nil)

        }

        else

        {

            // error msg

        }

    }

    

    //Mark- UIImagePickerController Delegate

    

    func imagePickerControllerDidCancel(picker:UIImagePickerController)

    {

        self.dismissViewControllerAnimated(true, completion: nil)

    }

    

    func imagePickerController(picker:UIImagePickerController!, didFinishPickingMediaWithInfo info:NSDictionary)

    {

        if(picker.sourceType == UIImagePickerControllerSourceType.Camera)

        {

            // Access the uncropped image from info dictionary

            var imageToSave: UIImage = info.objectForKey(UIImagePickerControllerOriginalImage) as UIImage

            var imageToSave1: UIImage = info[UIImagePickerControllerOriginalImage] as UIImage //same but with different way

            

            UIImageWriteToSavedPhotosAlbum(imageToSave, nil, nil, nil)

            

            self.savedImageAlert()

            self.dismissViewControllerAnimated(true, completion: nil)

        }

       

    }

    

    

    

    

    func savedImageAlert()

    {

        var alert:UIAlertView = UIAlertView()

        alert.title = "Saved!"

        alert.message = "Your picture was saved to Camera Roll"

        alert.delegate = self

        alert.addButtonWithTitle("Ok")

        alert.show()

    }
