imageview not updating after an image is picked - ios

Question

I have the following problem. I use a imagepickerdelegate to choose a image from my photo library and to apply this in the UIImageView. The problem is that it won't update the UIImageview with my chosen image.
I inherit both
UIImagePickerControllerDelegate, UINavigationControllerDelegate
This is my image view.
let profileImageView: UIImageView = {
let imageView = UIImageView()
imageView.translatesAutoresizingMaskIntoConstraints = false
imageView.layer.cornerRadius = 99 / 2
imageView.layer.masksToBounds = true
imageView.image = UIImage(named: "profileimg")
imageView.contentMode = .scaleToFill
return imageView
}()
Then the functions to handle choosing and setting the image inside the UIImageView look like these.
func addProfilePhoto() {
let imagePicker = UIImagePickerController()
imagePicker.delegate = self
imagePicker.allowsEditing = true
imagePicker.sourceType = .photoLibrary
imagePicker.mediaTypes = UIImagePickerController.availableMediaTypes(for: .photoLibrary)!
present(imagePicker, animated: true, completion: nil)
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
var selectedImageFromPicker: UIImage?
if let editedPickedImage = info[UIImagePickerControllerEditedImage] as? UIImage {
selectedImageFromPicker = editedPickedImage
} else if let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage {
selectedImageFromPicker = pickedImage
}
if let selectedImage = selectedImageFromPicker {
print("set image")
DispatchQueue.global(qos: .userInitiated).async {
DispatchQueue.main.async {
self.profileImageView.image = selectedImage
self.dismiss(animated: true, completion: nil)
}
}
}
}
func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
dismiss(animated: true, completion: nil)
}
My log gives the following messages when I tap on the UIImageView:
[Generic] Creating an image format with an unknown type is an error
And when I choose an image it confirms that there is an image but it won't show.
set image
Any idea what I am doing wrong?

I checked your code, seem you have not code for display profileImageView on screen. So, you do not see it. Example:
profileImageView.frame = ........
self.view.addSubview(profileImageView)
