How to share a Note including Markup with Share Extensions Swift - swift

Question

I've already figured out how to share the general content of a Note (text and pictures). But the way I currently approach the problem the markup of the note is not kept (Titles, Lists, etc.). I just receive the pure text of the note. When you share a note with Mail for instance, you can see that the markup is transferred. Is there a way to do that for your own apps?
My current solution where I only receive the pure text:
class ShareViewController: UIViewController{
override func viewDidLoad() {
if let content = extensionContext!.inputItems[0] as? NSExtensionItem {
// Verify the provider is valid
if let contents = content.attachments as? [NSItemProvider] {
// look for images
for attachment in contents {
print(attachment.registeredTypeIdentifiers)
if attachment.hasItemConformingToTypeIdentifier("public.plain-text"){
attachment.loadItem(forTypeIdentifier: "public.plain-text", options: nil) { data, error in
let string = data as! String
print(string)
}
}
}
}
}
}
}
EDIT:
My current NSExtensionActivationRules:
<key>NSExtensionAttributes</key>
<dict>
<key>NSExtensionActivationRule</key>
<dict>
<key>NSExtensionActivationDictionaryVersion</key>
<integer>2</integer>
<key>NSExtensionActivationSupportsImageWithMaxCount</key>
<integer>100</integer>
<key>NSExtensionActivationSupportsText</key>
<true/>
</dict>
</dict>

Answer 1

Use the attributedContentText property of your NSExtensionItem (content):
override func viewDidLoad() {
if let content = extensionContext!.inputItems[0] as? NSExtensionItem {
// move your content validation to `func isContentValid() -> Bool`
let attributedString = content.attributedContentText // yay NSAttributedString!
}
}
