Unable to reference in code.

I added the line pod "Koyomi" to my podfile and did the pod install and that seemed to work fine, then I went to my Main.storyboard and I dragged a collection view. I then chose its class to be Koyomi in the identity inspector, and everything seemed to still be fine. I see the options to modify it in the attributes inspector, but then when I try to control-drag it to my .swift file, it gives me the following errors:
any help with this would be much appreciated.
