| === Description |
| |
| The `VK_MVK_ios_surface` extension is an instance extension. |
| It provides a mechanism to create a slink:VkSurfaceKHR object (defined by |
| the `apiext:VK_KHR_surface` extension) based on a code:UIView, the native |
| surface type of iOS, which is underpinned by a basetype: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| superseded by the `apiext:VK_EXT_metal_surface` extension. |
