Invalid Image Path - No image found at the path referenced under key "CFBundleIconFile": Icon.png

Sounds like you may, like me, have accepted the suggestion by XCode 5.0 to migrate your icon files to a catalog.

When you do that, you need to remove the CFBundleIconFile ("Icon file") parameter from your project's .plist file. That's the old way of doing this, and once you've migrated your icon files, obviously that parameter is incorrect.

Strange that XCode's migration doesn't fix this for you automatically. Would have been so very Apple to help you out there.

If your app supports iOS 5.0 and up, moving all icon files to the Asset Catalog will work.

If your app still needs to support lower versions of iOS (like mine), the solution is to use the CFBundleIconFiles key in the project plist file. In my case, my app is an iPhone-only app, so I did the following:

1. Prepare 8 icon files: two app icons for iOS6 and earlier (57x57 and 114x114), two icons for iOS7 (60x60 and 120x120), two icons for spotlight search/settings for iOS 6 and earlier (29x29 and 58x58), and two icons for spotlight (40x40 and 80x80). The files must be PNG files. Name these files whatever you want, but the high-resolution file name must in the form of [email protected]
2. In the project plist file, edit the CFBundleIconFiles key (which is an array) to include the names of the above icon files. Only the low resolution file names are needed, and the extension (.png) should not be included. The Xcode will automatically find the high resolution files as long as their names follow the convention (with @2x).
3. Make sure your project does not contain the Asset Catalog folder
4. If you did the above things right, when you check the "General" section of the app target, you should see that Xcode has listed all the icon files in right place under the "app icons" section.
5. If your app needs to support iOS 3.1 and earlier, you need to make four extra icon files. The size and the name of these files are as follows: Icon.png (57x57), [email protected] (114x114), Icon-Small.png (29x29), [email protected] (58x58). The fixed names are required by iOS and cannot be changed. But as long as you name the icon files that way, you don't need to do any extra things.

After these steps, you should not have any problems with the icons when uploading your app to the App Store.

The Asset Catalog simplies some of the above steps, e.g, generating low resolution icon files (my guess).

I got the above info from "iOS Human Interface Guidelines", "iOS app programming guide" and "information property list reference". Search for "app icons" and everthing is explained.

My solution was: in 'build phases', under 'copy bundle resources', click '+' and choose all your icons.

good luck.
