How to allow and get Memoji Stickers in a text field

I'm trying to use Memoji Stickers on my app, but neither UITextField or TextField from SwiftUI displays them on the keyboard. How can I make them show up, and how do I retrieve them afterwards?

I tried different text input traits, but had no success. I even tried using the Twitter keyboard option, because the stickers work in the Twitter app, but it was to no avail.

Here's a picture of how it shows up for me in apps that support it, like WhatsApp, Telegram and Twitter

So... how you can get it is to implement the paste method on the view controller where your textfield/view is.

Then you can grab the image from the pasteboard. Basically

Objective-C

UIImage *image = [[UIPasteboard generalPasteboard] image];

or Swift

let image = UIPasteboard.general.image

Which will let you find the UIImage then you can wrap it in

Objective-c NSAttributedString *memojiStrong = [[NSAttributedString alloc] initWithAttributedString: image];

Swift

let memojiString = NSAttributedString(attachment: image)

This will let you add it as a string to whatever you need to add it to. You can find a little more for the image -> String if you want to save it for an image: https://www.hackingwithswift.com/example-code/system/how-to-insert-images-into-an-attributed-string-with-nstextattachment
