Скачать или смотреть Environment, Modifiers and a Camera Feed - RealtimeSwift Devlog #3

In this video, I continue my devlog showing the development of my SwiftUI-style declarative rendering engine, RealtimeSwift. Today, I focus on implementing modifiers and the environment, and I even manage to render some video onto the screen. I start by explaining the goal of integrating a source registry into the app state, which allows access to PixelBufferLayers by source name. I demonstrate how CameraSource implements PixelBufferLayerSource to connect to external cameras and create CIImages. I also discuss the environment, which is managed during rendering and passed through recursive resolve() calls, allowing modifications down the view hierarchy. I showcase the RealtimeEnvironmentValues implementation, which defines keys and stores them, similar to SwiftUI, and introduce a property wrapper for accessing it from views. I explore how the .environment() modifier works, detailing the process of keying objects and returning ModifiedRealtimeContent. Finally, I present a demo of the current test project! Prepare to be underwhelmed...
