RoyalVNC is a modern, high performance implementation of the VNC/RFB protocol written in Swift. The SDK (RoyalVNCKit) is compatible with Swift, Objective-C, C and C# on macOS, iOS, iPadOS, Linux and Windows. It has no external dependencies but includes some free (public domain) third party code from the libtommath, libtomcrypt and D3DES libraries (see Credits).

- Support for 8-bit, 16-bit and 24/32-bit color depths with high-performance framebuffer implementations.
- Clipboard redirection support for text in both ways (remote to local and local to remote).
- Connection state management and rendering is decoupled from each other, so it's possible to build "headless" clients (ie. no rendering of the remote desktop).
- The SDK includes a ready-to-use implementation of a framebuffer view for macOS (subclass of
NSView), which also handles mouse and keyboard input, local cursor (NSCursor), scaling and rendering. The iOS/iPadOS equivalent (UIView) is a work-in-progress. - First-class error handling. The
VNCErrortype divides all possible errors into three broad categories: Protocol, Authentication and Connection errors. There are helper functions to retrieve human-readable descriptions for all errors and a convenience functions that allows the SDK consumer to distinguish between errors that should be displayed to the user and ones that shouldn't. - Headless CLI demos (one using Swift and another one using the C API) are included in the repository.
- The repository also contains C# bindings so the library can be used with .NET.
- This repository contains Demo/Sample clients for macOS (one written in Swift, one in Objective-C) and iOS/iPadOS.
