title: Add many images to xcodes asset catalog - how to manage naming and 1x,2x,3x for each?
body: <p>I have an app where I would like to add many images (500+) to xcode's asset catalog. Adding the 1x images was easy, I simply had to drag the first folder. However to add the 2x and 3x images it seems I would need to drag each image in manually, and I'd prefer not to do that. The 3 different sizes for each image are all named the same, w/ just different sizes. Is there anyway to automate this process?</p>
