How to define notification icon?

[made-by-chris]

I successfully set the application icons using an 'AppIcon' set in images.xcassets
The system notification doesn't use any icons though, just the default 'blank' icon.
How can I set it?
Thanks! I love this project.

Have you provided all the sizes? I added some sample icons in 4c0dda6 and it works on my machine. If it doesn’t show, try killing Notification Center in Activity Monitor to clear cache.

Thanks a lot, I will try this.
