I saw that it's possible — iBooks application does it.
Is it any way to do it?

I wrote a category to support image for UIMenuItem. It's based on method swizzling, but should be safe in most cases.

There is nothing in the current official API do that. UIMenuItem can only be initialised with -initWithTitle:action:
I suspect that Apple either using a private API or have implemented a custom control. Probably the former.

Check Emoji & Symbols, perhaps it will fit to your purpose.
Go to your Xcode Menu -> Edit -> Emoji & Symbols.
Ex.:
let menuItemYes = UIMenuItem(title: "✅", action: "doSomething")
Good luck!
