RealtimeSwift - my declarative video rendering framework

RealtimeSwift if the declarative rendering framework behind my suite of connected video apps CueCam Presenter, Video Pencil and Shoot.I reimplemented most of SwiftUI from scratch in a way that lets me produce video frames for recording, streaming or sending to a virtual camera.
It took me about nine months from start to finish, with another month of bug fixes once it hit production in CueCam.
Ask me anything.
