How can I use this in Swift 4?

Thank you for this, I've been looking for an animated typing indicator like the following:
Animation type 1 (preference): https://media.tenor.com/-iQZrXlyW2oAAAAC/typing-dots.gif
Animation type 2: https://gifimage.net/wp-content/uploads/2017/11/imessage-typing-indicator-gif-5.gif

My preference for my app is Animation type 1, though any would do at this point.

I'm trying to get this repo running in Swift 4, Xcode 14+. Is it compatible and if so, how can I get the demo running?
