UIImagePickerController crashes app | Swift3, Xcode8

FYI: I´m new to Swift so this might be a really simple problem but I just can´t figure it out.

I have been following the Start Developing iOS Apps (Swift) tutorial using the Xcode 8 beta and Swift 3.

I attached a Tap Gesture Recognizer to a Image View and then added this action in the ViewController.swift :

@IBAction func selectImageFromPhotoLibrary(_ sender: UITapGestureRecognizer) {
        // Hide the keyboard.
        nameTextField.resignFirstResponder()

        // UIImagePickerController is a view controller that lets a user pick media from their photo library.
        let imagePickerController = UIImagePickerController()

        // Only allow photos to be picked, not taken.
        imagePickerController.sourceType = .photoLibrary

        // Make sure ViewController is notified when the user picks an image.
        imagePickerController.delegate = self

        present(imagePickerController, animated: true, completion: nil)
    }

When the selectImageFromPhotLibrary Action is called by a tap on the Image View the app crashes without showing the ImagePicker.

I guess that the problem is with the new present instead of presentViewController which was introduced in Swift 3

import UIKit

class ViewController: UIViewController, UITextFieldDelegate, UIImagePickerControllerDelegate, UINavigationControllerDelegate {

    // MARK: Properties
    @IBOutlet weak var mealNameLabel: UILabel!
    @IBOutlet weak var nameTextField: UITextField!
    @IBOutlet weak var photoImageView: UIImageView!


    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.

        //  Handle the text  field´s user input through delegate callbacks
        nameTextField.delegate = self
    }

    // MARK: UITextFieldDelegate
    func textFieldShouldReturn(_ textField: UITextField) -> Bool {
        // Hide the keyboard.
        textField.resignFirstResponder()
        return true
    }

    func textFieldDidEndEditing(_ textField: UITextField) {
        mealNameLabel.text = textField.text
    }

    // MARK: UIImagePickerControllerDelegate
    func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
        // Dismiss the picker if the user canceled.
        dismiss(animated: true, completion: nil)
    }

    func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
        // The info dictionary contains multiple representations of the image, and this uses the original.
        let selectedImage = info[UIImagePickerControllerOriginalImage] as! UIImage

        // Set photoImageView to display the selected image.
        photoImageView.image = selectedImage

        // Dismiss the picker.
        dismiss(animated: true, completion: nil)
    }


    // MARK: Actions

    @IBAction func selectImageFromPhotoLibrary(_ sender: UITapGestureRecognizer) {
        // Hide the keyboard.
        nameTextField.resignFirstResponder()

        // UIImagePickerController is a view controller that lets a user pick media from their photo library.
        let imagePickerController = UIImagePickerController()

        // Only allow photos to be picked, not taken.
        imagePickerController.sourceType = .photoLibrary

        // Make sure ViewController is notified when the user picks an image.
        imagePickerController.delegate = self

        present(imagePickerController, animated: true, completion: nil)
    }

    @IBAction func setDefaultLabelText(_ sender: UIButton) {
        mealNameLabel.text = "Default Text"
    }


}

Solution 1:

Add this key to your info.plist,

Key : Privacy - Photo Library Usage Description [ NSPhotoLibraryUsageDescription ]
String Value : We need access to your camera roll and photo library, so that we can do operations on it. [ Customise it in your own way] 

That's it, Clean & Run the project.

Solution 2:

In xcode 8 new key is added Privacy For -

Media,Location,Photo Library,Reminders,Motion,Calender,Bluetooth,HomeKit,Camera,Contacts etc.. and value is Description for the privacy you will access for.For ex. "We need access to use photo library to make functionality work" or ANY_YOUR_APP_RELATED_DESCRIPTION.

Solution 3:

Noticed a camera key and value needed for camera usage as well.

Keys required for both the camera and photo library that need to be in the info.plist:

<key>NSCameraUsageDescription</key>
<string>Access needed to use your camera.</string>

<key>NSPhotoLibraryUsageDescription</key>
<string>Access needed to photo gallery.</string>
