Do I still need low-resolution images for using Interface Builder when developing iPhone app for iOS 7?

Solution
You are correct that an iOS 7 iPhone-only app is not going to run on any single-resolution devices, so you only need to provide double-resolution images. Do what you have always done in the past: refer to your image as `myImage` but name the actual image file `myImage@2x.png`. Even better, use the asset catalog! Place the double-resolution image in the `2x` slot and refer to it by the name of that image set. Either way, this will work perfectly both in the storyboard editor and in the running app; in the storyboard editor, the Media Library and things like buttons that have images will display your image's name as `myImage`.
Problem
I started to develop an iPhone app for iOS 7. Since iOS 7 does not support devices with non-retina display for the iPhone/iPod touch, and it uses high-resolution images on non-retina iPads (iPad 2 and iPad mini) in the iPhone emulation mode, now I think we don't need to provide low-resolution images when developing an iPhone-only app which deployment target is iOS 7. I thought it's great, but soon I faced a problem when I used a Storyboard; apparently Interface Builder can not display high-resolution images which file names end with @2x. I feel it's really pity that we have to provide the low-resolution images ONLY for the Interface Builder... Is there any good workaround for this? Or do we still have to provide low-resolution images if we want to use the Interface Builder?
