Excuse me, have you found a solution?

I recently encountered this issue and successfully reproduced it.

After entering text in Korean into a UITextView, if you input multiple ✔️ emojis on the next line and insert line breaks between the emojis, they don't appear as one per line; instead, they appear two at a time. Deleting the emojis that are displayed two at a time leads to the mentioned error.

I haven't found a solution yet, but I wanted to share this information first.

    if valid {

    let validString = String(String.UnicodeScalarView(validScalars))
