Share Sheet with UIActivityItemsConfiguration

I am trying to address an issue with my app’s share sheet where, when the user sends a URL to either Apple Reminders or OmniFocus, the receiving app does not get a title. So I am updating my share sheet code to use UIActivityItemsConfiguration.

I have this code:

let title = "Golden Hill Software"
let url = URL(string: "https://www.goldenhillsoftware.com/")!

let itemProvider = NSItemProvider()

itemProvider.registerObject(ofClass: URL.self, visibility: .all) { (handler) in
	handler(url, nil)
	return nil
}

let config = UIActivityItemsConfiguration(itemProviders: [itemProvider])

config.metadataProvider = { (key) in
	if key == .title || key == .messageBody {
		return title
   } else {
	   return nil
   }
}

let viewController = UIActivityViewController(activityItemsConfiguration: config)
self.present(viewController, animated: true)

This works with some share sheet extensions. But when I choose the Ivory share extension, Ivory creates a post with a URL that starts with bplist…. When I choose the Open in Chrome action extension, Chrome says “Chrome cannot handle this link”.

Can someone help me understand what I am doing wrong here? (edited)
