Use URL object in share sheet item

[ktprograms]

Allows using URL-specific share sheet actions.

Fix: #325

It might read better to shorten the six lines for items into one through nil coalescing

[ktprograms]

@anohren I can't see how that's possible, since it'd be of different types.

[anohren]

As long as the type annotation is [Any] the types should all be inferred as Any. Does that not work?

let items: [Any] = [ URL(string: url) ?? url ]

Ah, Thanks! Didn't know it worked like that.

No problem!

You can think of it as equivalent to e.g:

let s: String? = "a non-optional string"
let e: MyProtocol = MyConformer()

where the compiler knows to wrap your string in Optional.some, and to turn your value into the existential any MyProtocol only from reading your type annotations.
