ios - UIImagePickerController in Swift 3

Question

I've recently updated to Swift 3 in Xcode 8 using the developer beta. I'm trying to implement Firebase Auth, and everything's going well.

My Problem:

I'm trying to upload an image as a user's profile picture to a Firebase database.

I thought I could use the UIImagePickerController to do this, but when I do, I get a

"Thread 7: Signal SIGABRT

I know what this would normally indicate, but I checked, and my image does indeed print my test statement when I tap it.

My failed method:

ViewController.swift

import UIKit
import Firebase
import Photos

class ViewController: UIViewController, UITextFieldDelegate, UIImagePickerControllerDelegate, UINavigationControllerDelegate{

@IBOutlet weak var imageView: UIImageView!
@IBOutlet var emailTextField: UITextField!
@IBOutlet var passWordTextField: UITextField!
@IBOutlet var nameTextField: UITextField!

override func viewDidLoad() {
        super.viewDidLoad()

        if FIRAuth.auth()?.currentUser?.uid != nil {
            let storyboard = UIStoryboard(name: "Main", bundle: nil)
            let view = storyboard.instantiateViewController(withIdentifier: "ProfileViewController")
            self.present(view, animated: true, completion: nil)
        }

        imageView.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(handleSelectProfileImageView)))
        imageView.isUserInteractionEnabled = true

        self.emailTextField.delegate = self;
        self.passWordTextField.delegate = self;
        self.nameTextField.delegate = self;
    }

func handleSelectProfileImageView() {
    let picker = UIImagePickerController()

    picker.delegate = self
    picker.allowsEditing = true

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

I'm not sure yet if this is just a problem with Swift 3 and the developer Xcode 8 beta, or if I'm just doing it the wrong way for swift 3.

EDIT:

I'm using the GM Version of xcode8, but still get that same error.

Answer 1

I think you need to add privacy - key for camara and photo library in your info.plist file as from xcode 8. for example,

 Key : Privacy - Media Library Usage Description
 Value : YES 

 Key : Privacy - Photo Library Usage Description
 Value : YES 

 Key : Privacy - Camara Usage Description
 Value : YES 

here value is string not Boolean.

so try this.

Check Apple documentation for more details!
