Description

The VK_MVK_ios_surface extension is an instance extension. It provides a mechanism to create a VkSurfaceKHR object (defined by the VK_KHR_surface extension) based on a UIView, the native surface type of iOS, which is underpinned by a CAMetalLayer, to support rendering to the surface using Apple’s Metal framework.

Deprecation by VK_EXT_metal_surface

The VK_MVK_ios_surface extension is considered deprecated and has been superseded by the VK_EXT_metal_surface extension.
