Raw Normal View History

Introducing RCTSurface, new experimental thread-safe interop layer Summary: RCTSurface instance represents React Native-powered piece of a user interface which can be a full-screen app, separate modal view controller, or even small widget. It is called "Surface". The RCTSurface instance is completely thread-safe by design; it can be created on any thread, and any its method can be called from any thread (if the opposite is not mentioned explicitly). The primary goals of the RCTSurface are: - ability to measure and layout the surface in a thread-safe and synchronous manner; - ability to create a UIView instance on demand (later); - ability to communicate the current stage of the surface granularly.
