<key>CFBundleIcons</key>
<dict>
<key>CFBundleAlternateIcons</key>
<dict>
<key>i2</key>
<dict>
<key>CFBundleIconFiles</key>
<array> <string>i2-60</string></array>
</dict>
<key>i3</key>
<dict>
<key>CFBundleIconFiles</key>
<array> <string>i3-60</string> </array>
</dict>
<key>i4</key>
<dict>
<key>CFBundleIconFiles</key>
<array> <string>i4-60</string> </array>
</dict>
</dict>
<key>CFBundlePrimaryIcon</key>
<dict>
<key>CFBundleIconFiles</key>
<array> <string>AppIcon</string> </array>
</dict>
</dict>
