“Creating an image format with an unknown type is an error” with UIImagePickerController

Question

While choosing an image from the image picker in iOS 10 Swift 3 I am getting an error - Creating an image format with an unknown type is an error

Answer 1

If this helps anyone, I had this happen when I subclassed UIImageView to create a rounded view. It also happened when I added the below line in viewDidLoad()

imageView.layer.cornerRadius = self.imageView.frame.size.width / 2

I ended up adding the line in viewWillLayoutSubViews and it worked. See this for more details:
