General Ah it's actually a little more complicated, as the storyboard is attached to the assets catalog which also has your images in it. So It's not something I can just create a drop in for.
You can check out this script which is what I use to generate most of ours:
It generates an Assets.car that contains the icons and the resources for the storyboard.
Otherwise if you send me your 1024x1024 icon I can run it for you.
