Keep Getting an Error: "Uiimagepickercontroller Extension Discovery Failed with Error: (Null)"

UIImagePickerController extension discovery failed with error: (null)

I checked the details, and there are no issues in your implementation.
I also checked the apple's official sample here.
https://developer.apple.com/documentation/uikit/uiimagepickercontroller/customizing_an_image_picker_controller
Same result!

Finally, this is an issue related to iOS Simulators(version 11.3.1).
FYI, I found iPhone 11 Pro Max didn't work in some previous versions, but iPhone 8 and some others worked.
I just want you guys not wasting time on this. Move ahead.

Thanks.

Swift 4 errors encountered while discovering extensions - photo will not load on UI

Two issues:

• The signature of didFinishPickingMediaWithInfo is wrong. In Swift 3+ it is

  func imagePickerController(_ picker: UIImagePickerController, 
                             didFinishPickingMediaWithInfo info: [String : Any])
  

• The delegate method must be on the top level of the class (not in another method)

  @IBAction func edit_click(_ sender: Any) {
  
      //select ava
      let picker = UIImagePickerController()
      picker.delegate = self
      picker.sourceType = .photoLibrary
      picker.allowsEditing = true
      self.present(picker, animated: true, completion: nil)
  }
  
  func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
  
      //selected image
      let image = info[UIImagePickerControllerEditedImage] as? UIImage
      avaImg.image = image
      self.dismiss(animated: true, completion: nil)
  }
  

Xamarin Forms iOS UIImagePickerController not shown when called from a modal page (formsheet)

Thanks to @Cheesebaron I could fix the problem.
This is working on my end.

public Task<Stream> GetImageStreamAsync()
        {
            // Create and define UIImagePickerController
            imagePicker = new UIImagePickerController
            {
                SourceType = UIImagePickerControllerSourceType.PhotoLibrary,
                MediaTypes = UIImagePickerController.AvailableMediaTypes(UIImagePickerControllerSourceType.PhotoLibrary),
                //ModalPresentationStyle = UIModalPresentationStyle.FormSheet,
            };

            // Set event handlers
            imagePicker.FinishedPickingMedia += OnImagePickerFinishedPickingMedia;
            imagePicker.Canceled += OnImagePickerCancelled;

            // Present UIImagePickerController;
            UIViewController currentController = UIApplication.SharedApplication.KeyWindow.RootViewController;
            while (currentController.PresentedViewController != null)
                currentController = currentController.PresentedViewController;
   
            currentController.PresentViewController(imagePicker, true, null);

            // Return Task object
            taskCompletionSource = new TaskCompletionSource<Stream>();
            return taskCompletionSource.Task;
        }

Thanks for helping out!
