I found some related posts:
UIImagePickerControllerDelegate to Swift?
how to capture camera with UIImagePickerController in swift?
But none of them works for beta 3 because the UIImagePickerControllerDelegate changed:
func imagePickerController(picker: UIImagePickerController!, didFinishPickingMediaWithInfo info: [NSObject : AnyObject]!)
My question is how to get UIImage object from info Array? Thanks
Its a dictionary, index it with UIImagePickerControllerOriginalImage
let image = info[UIImagePickerControllerOriginalImage] as UIImage
