Xcode 7 - Missing Retina 4 support in image.xcassets

Question

In xcode 7 there is no way to display image 4 of the retina. I am creating a simple picture with the addition of a background image in my xib file. I created an image. Imagecaxets from the background image added 1x (320 * 480), 2x (640 * 960), 3x (1248 * 2208) resolution images. But when I use this image installed in my xib file, it only shows the correct image for iphone 4 and iphone 4s. I changed the Aspectfit mode. After that, he began to show the fields above and below. Please help me.

Thank you in advance
