Why don't I see my app icon in iOS?

I’m building an app and I now want to add an app icon in iOS. So following this tutorial I added the following lines between the <widget> tags in my config.xml:

<platform name="ios">
    <!-- iPhone / iPod Touch -->
    <icon src="icons/ios/icon.png" width="57" height="57" />
    <icon src="icons/ios/icon@2x.png" width="114" height="114" />

    <!-- iOS 7.0+ -->
    <!-- iPhone / iPod Touch -->
    <icon src="icons/ios/icon-60.png" width="60" height="60" />
    <icon src="icons/ios/icon-60@2x.png" width="120" height="120" />

     <!-- iPhone Spotlight and Settings Icon -->
    <icon src="icons/ios/icon-small.png" width="29" height="29" />
    <icon src="icons/ios/icon-small@2x.png" width="58" height="58" />

On Android the icon shows perfectly well, but on iOS I don’t see any of the icons (which is basically all the same file but renamed).

Does anybody know what I’m doing wrong? All tips are welcome!

Are you sure the paths are correct? If they are, you could try to remove the platform and then add it back.
