I\'m not sure what I did to get this error in Xcode 5:
\"None of the input catalogs contained a matching app icon set named \"AppIcon\"\".
My app was build
I had imported all the images from a folder into images.xcassets at once then started getting build failed.I tried deleting one image set at a time and build (⌘b) until I get the project build properly and understood one image set causing issue. Then continued deleting one image from that image set and build (⌘b) until I get build succeeded and found the culprit!. Because a different format file had been renamed to PNG.
