title: Do i need to use Xcode's Image.xcassets New image set and New OSX Icon
body: <p>I'm using Xcode 6.1 making a universal device app.  I have launch images and app icons for iOS 6, 7, and 8. What's the purpose of a New Image Set and a New OSX Icon in Image.xcassets. Do i have to put my images in there? I just put my images in supporting files and drag and drop into UIImageView from supporting files. Am i doing it wrong? Am i supposed to instead put all my images in New Image Set instead and not put anything in supporting files? Can i just use supporting files instead of New Image Set? Apple says New OSX Icon contains all representations of an Icon that OSX Icon provides. What Icons are they referring to? Do i have to put all my App Icons in New OSX Icon again instead of supporting files?</p>
