For a long time there hasn't been a Discord library written in Swift. A lot of the libraries are outdated and no longer maintained. Although there are a few options now, Discord.swift aims to be the library of choice. It implements the latest Discord API features, elegant and easy to use.
Its been in development for the past year or so and I finally feel confident enough to showcase my work. It has pretty much everything implemented the Discord API has to offer! It will consistently be updated to fix any issues and to implement the latest features.
Thank you for taking the time to read! I hope you check out the library! 
Any feedback is welcome!
