I am trying to use an image picked using the standard UIImagePickerController in iOS 11. No matter how hard I try it just keeps showing this error:

errors encountered while discovering extensions: Error Domain=PlugInKit Code=13 "query cancelled" UserInfo={NSLocalizedDescription=query cancelled

I can actually pass the UIImage to the setter method, I can see the image in the inspector, but when I set it as a background image of a UIButton, it's just a plain black colour and when the UIImagePickerController dismisses, I get the error above.

I did request use the PHPhotoLibrary.requestAuthorization and YES I have Read and Write access to Photos.

Any ideas?

Perhaps you did not use UIImagePickerControllerOriginalImage or UIImagePickerControllerEditedImage but rather another non-image editing option for UIImagePickerController.

I experienced the same/similar error. enter image description here

The app ran yet the image showed as black. The line I used to assign the image originally looked like this:

let pickedImage = info[UIImagePickerControllerPHAsset] as? UIImage

and was resolved by changing the line to this: 

let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage

I just had this error what worked from me is adding the uinavigationcontrollerdelegate to my file and then declaring the uiimagepickercontroller as self in the view did load. example

class notesview: UIViewController,UIImagePickerControllerDelegate, UINavigationControllerDelegate{
var imagePicker = UIImagePickerController()
viewdidload(){
imagepicker.delegate = self

}
 }
