How to build a font generator in iOS Swift and allowing pasting to clipboard

Question

In order to display fonts from the UIFonts framework, I'm now creating a listview. To use, UIPasteboard.general.string the fonts are not copied to the clipboard and only the plain text is transferred. I've tried including the MobileCoreServices framework and use kUTTypeRTF to implement it. 

But there isn't any in-depth material available.

Would you please tell me how to create a custom font list that allows text to be selected, styled, and pasted into other programmes (like Notes or Facebook posts) precisely like the font generator offered online?

I'm now working on the next two UIFonts, however I can't paste from the clipboard without losing the formatting.

let fonts: [String] = ["BodoniSvtyTwoOSITCTT-Book", "ChalkboardSE-Regular"]

On your iPhone, you cannot copy and paste text that has a font.

Also unable to achieve this is FancyLetters. You are only shown characters that appear to be printed.

The letter "A," for instance, can be written as "A," "A," or "A." But as StackOverflow prohibits it as well, this material has not been edited in any way. These characters are found in the Unicode table. They are the same characters as "A" or "B," but the keyboard won't print them for you without certain modifiers, such as

SHIFTOPTIONK = .

Unicode characters are overlaid with any font.

I suggest reading the fantastic essay Emoji under the hood. It teaches a lot about the design of characters and how they are displayed on various devices in addition to how emoji are produced on devices.
