<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>CFBundleIconFiles</key>

<array> <string>i4-60</string> </array>

</dict>

</dict>

<key>CFBundlePrimaryIcon</key>

<dict>

<key>CFBundleIconFiles</key>

<array> <string>AppIcon</string> </array>
