MediaPipeTasksDecision Framework Reference

DecisionMakerDelegate

enum DecisionMakerDelegate: Sendable, Equatable, Hashable, RawRepresentable

Hardware delegate selection for running MediaPipe Decision inference on Apple platforms.

• cpu

  CPU execution (XNNPACK / LiteRT CPU).

  Declaration

  Swift

  case cpu

• gpu

  GPU execution (Metal / LiteRT GPU).

  Declaration

  Swift

  case gpu

• init(rawValue:)

  Creates a new instance with the specified raw value.

  If there is no value of the type that corresponds with the specified raw value, this initializer returns nil. For example:

  enum PaperSize: String { case A4, A5, Letter, Legal }

  print(PaperSize(rawValue: "Legal")) // Prints "Optional(PaperSize.Legal)"

  print(PaperSize(rawValue: "Tabloid")) // Prints "nil"

  Declaration

  Swift

  init?(rawValue: Int32)

  Parameters

  rawValue

  The raw value to use for the new instance.

• rawValue

  The corresponding value of the raw type.

  A new instance initialized with rawValue will be equivalent to this instance. For example:

  enum PaperSize: String { case A4, A5, Letter, Legal }

  let selectedSize = PaperSize.Letter print(selectedSize.rawValue) // Prints "Letter"

  print(selectedSize == PaperSize(rawValue: selectedSize.rawValue)!) // Prints "true"

  Declaration

  Swift

  var rawValue: Int32 { get }
