title: Xcode 6 asset catalog automatically create images for smaller scales
body: <p>With the need of 3x images in iOS 8 I figured it would be easier to manage images with an asset catalog in Xcode 6. I am trying to just provide a single image, the 3x scaled image to the asset catalog and I want Xcode to automatically downscale that image to generate 2x and 1x versions of the 3x image, so that I don't have to do it manually.</p>
  
  <p>Right now this is what I have:

  <p>I really hope that Xcode has such a feature to automatically create 2x and 1x images and I just have not discovered it yet. If there isn't any such feature, are there any alternatives? (I know IconKit but it is annoying and hasn't been updated to support 3x images. If it was made properly in the first place it wouldn't even need an update..)</p>
  
  <p>I know that Xcode automatically can generate all images from a vector pdf, but thats not what I am looking for!</p>
