CVBuffer.Attributes

struct · iOS 26.0+ · SDK 27.1

@dynamicMemberLookup struct Attributes

A partial set of pixel buffer creation attributes. This struct is useful for conveying partial requirements for pixel buffers to clients. This struct makes all properties of ``CVPixelBuffer/CreationAttributes`` optional.

Swift declaration

init(rawAttributes: [String : any Sendable])

get · iOS 26.0+

pixelFormatTypes

TypeScript

get pixelFormatTypes(): (Array<CVPixelFormatType>) | null

Swift declaration

var pixelFormatTypes: [CVPixelFormatType]? { get set }

Allow multiple pixel formats to be specified in attributes Setting this property will override the single format value set by ``CreationAttributes/pixelFormatType`` and vice-versa. When accessing ``CreationAttributes/pixelFormatType``, only the first value is used if multiple format values are set. Do not set this value to an empty array.

pixelFormatTypes

TypeScript

set pixelFormatTypes(value: (Array<CVPixelFormatType>) | null)

Swift declaration

var pixelFormatTypes: [CVPixelFormatType]? { get set }

init · iOS 26.0+

init

TypeScript

static initMerging(values: Array<CVBuffer_Attributes>): (CVBuffer_Attributes) | null

Swift declaration

init?(merging values: [CVBuffer.Attributes])

Resolve multiple attribute specifications into a single instance. This is useful when you need to resolve multiple requirements between different potential clients of a buffer.

init · iOS 26.0+

init

TypeScript

static init(attributes: CVBuffer_CreationAttributes): CVBuffer_Attributes

Swift declaration

init(_ attributes: CVBuffer.CreationAttributes)

Convert CreationAttributes to Attributes
