=== iOS Platform

On iOS, all physical devices and queue families must: be capable of
presentation with any layer.
As a result there is no iOS-specific query for these capabilities.
Change log for February 27, 2017 Vulkan 1.0.42 spec update: * Bump API patch number and header version number to 42 for this update (the first anniversary edition). Github Issues: * Changed asciidoctor macros so cross-page links in the standalone reference pages function properly (public issue 462). Internal Issues: * Clarified host visibility discussion for slink:VkMemoryType, flink:vkInvalidateMappedMemoryRanges, elink:VkAccessFlagBits, and the <<synchronization-framebuffer-regions,Framebuffer Region Dependencies>> section, removing duplicated information and adding a central definition in the access types section (internal issue 552). * Change description of slink:vkGetPhysicalDeviceSurfacePresentModesKHR::pname:pPresentModes to return an array of values, not structures (internal issue 699). New Extensions: * Add a NOTE to the <<extensions,Layers & Extensions>> chapter describing the experimental status of `KHX` extensions. * Add new Khronos, Khronos Experimental, and vendor Vulkan extensions for release at GDC: VK_KHR_descriptor_update_template VK_KHR_push_descriptor VK_KHX_device_group VK_KHX_device_group_creation VK_KHX_external_memory VK_KHX_external_memory_capabilities VK_KHX_external_memory_fd VK_KHX_external_memory_win32 VK_KHX_external_semaphore VK_KHX_external_semaphore_capabilities VK_KHX_external_semaphore_fd VK_KHX_external_semaphore_win32 VK_KHX_multiview VK_KHX_win32_keyed_mutex VK_EXT_discard_rectangles VK_MVK_ios_surface VK_MVK_macos_surface VK_NVX_multiview_per_view_attributes VK_NV_clip_space_w_scaling VK_NV_geometry_shader_passthrough VK_NV_sample_mask_override_coverage VK_NV_viewport_array2 ** VK_NV_viewport_swizzle * Add new GLSL vendor extensions to support new builtin variables: GL_EXT_device_group GL_EXT_multiview 2017-02-26 22:54:26 -08:00			`[[platformQuerySupport_ios,platformQuerySupport_ios]]`
