Replace UITextView selected text with NSAttributedString

Question

I'm trying to replace some text that was selected inside a UITextView with some NSAttributedString but only the following method is available:

textView.replace(UITextRange, withText: String)

As you can see, replacing text only accepts a String and I cannot find way to replace it with an NSAttributedString.

One thing I could do is to store the whole UITextView attributedText and then perform the desired changes on a NSMutableAttributedString and then I can replace the UITextView.attributedText to be the one of the NSMutableAttributedString, but this comes with some issues for me.

If the text is already long with some NSStorage and NSAttachments this will be way more expensive.

Is there any workaround?

Because you can't intermix String and NSAttributedString, there's unfortunately no workaround that will let both co-exist in a text field.

But you should be able to use replaceCharacters(in:with:):

existingAttributedString.replaceCharacters(in: range, with: replacementAttributedString)
