I get this \"No image found at the path referenced under key \'CFBundleIcons\':\" error,
Cause Of Problem
This usually happens when Application Loader & iTunes Connect could not find an icon file with the specified name (AppIcon40x40 here) in your Icon directory.
Sometimes you may have all the required sizes of Icons added to your project but still you may find this error because of icon naming conflicts.
List Of Icon File Names iOS 7
Solution
Go To Info.plist->CFBundleIcons and compare all your actual icon files with the entries here(compare exact names), delete any extra ones here which may be causing this kind of an error during upload.
