[ios] How to allow user to pick the image with Swift?

You can do like here

var avatarImageView = UIImageView()
var imagePicker = UIImagePickerController()
        
func takePhotoFromGallery() {
    imagePicker.delegate = self
    imagePicker.sourceType = .savedPhotosAlbum
    imagePicker.allowsEditing = true
    
    present(imagePicker, animated: true)
}

func imagePickerController(_ picker: UIImagePickerController,
                           didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
    if let pickedImage = info[.originalImage] as? UIImage {
        avatarImageView.contentMode = .scaleAspectFill
        avatarImageView.image = pickedImage
    }
    self.dismiss(animated: true)
}
