# VkIOSSurfaceCreateInfoMVK(3) Manual Page

## Name

VkIOSSurfaceCreateInfoMVK - Structure specifying parameters of a newly created iOS surface object

Loading… please wait.

## C Specification

The VkIOSSurfaceCreateInfoMVK structure is defined as:

    // Provided by VK_MVK_ios_surface
    typedef struct VkIOSSurfaceCreateInfoMVK {
        VkStructureType               sType;
        const void*                   pNext;
        VkIOSSurfaceCreateFlagsMVK    flags;
        const void*                   pView;
    } VkIOSSurfaceCreateInfoMVK;

## Members

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `flags` is reserved for future use.

- `pView` is a reference to either a CAMetalLayer object or a `UIView` object.

## Description

Valid Usage

- VUID-VkIOSSurfaceCreateInfoMVK-pView-04143
  If `pView` is a CAMetalLayer object, it must be a valid CAMetalLayer

- VUID-VkIOSSurfaceCreateInfoMVK-pView-01316
  If `pView` is a `UIView` object, it must be a valid `UIView`, must be backed by a `CALayer` object of type CAMetalLayer, and vkCreateIOSSurfaceMVK must be called on the main thread

Valid Usage (Implicit)

- VUID-VkIOSSurfaceCreateInfoMVK-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_IOS_SURFACE_CREATE_INFO_MVK`

- VUID-VkIOSSurfaceCreateInfoMVK-pNext-pNext
  `pNext` must be `NULL`

- VUID-VkIOSSurfaceCreateInfoMVK-flags-zerobitmask
  `flags` must be `0`
