Since this is a private header, this should be TARGET_OS_IOSMAC instead.

Nit - let's update the comment after the #endif as well!

Code below uses a style with spaces between the @[ and the ], and it would be nice to be consistent.

I’m also surprised that we want an array with a single item that is a dictionary here, but I’m willing to believe it!

I think we need a comment about why we don’t do that on iOS running on Mac. It seems random and arbitrary without a comment, although arguably more terse and elegant. If the #if was something more along the rough lines of NSURL_SUPPORTS_TITLE, then it would be self explanatory; the comment would go where that is defined instead. I think that would be best. Following a pattern like PASTEBOARD_SUPPORTS_ITEM_PROVIDERS.

Ditto.

> +#if PASTEBOARD_SUPPORTS_ITEM_PROVIDERS && !ENABLE(MINIMAL_SIMULATOR)
>      title = [url _title];

Can we really do without the title? I understand that we can’t use the "_title" property. I am concerned because we may need the title for things like good quality rich links.

Is this the kind of hack we want to do to share code across the platforms? I don’t see this sort of thing elsewhere, but maybe we decided on this the past?

This combination of feature conditional plus platform conditional seems particularly inelegant. Is there a way to do better?

Why? Comment please.

You may be feeling that "a few things have to be off just for now, so I’ll just turn them off knowing I’m coming back here really soon”, but my past experience is that in practice there is lots of code like this many, many years later, so the comments may well be quite valuable. And if not, you can delete them.

This is temporary until we switch to NSItemProviders everywhere, which will hopefully be soon.
