TasksErrorCode

enum TasksErrorCode : UInt, @unchecked Sendable

@enum MPPTasksErrorCode This enum specifies error codes for errors thrown by iOS MediaPipe Task Library.

  • Indicates the operation was cancelled, typically by the caller.

    Declaration

    Swift

    case cancelledError = 1

  • Indicates an unknown error occurred.

    Declaration

    Swift

    case unknownError = 2

  • Indicates the caller specified an invalid argument, such as a malformed filename.

    Declaration

    Swift

    case invalidArgumentError = 3

  • Indicates a deadline expired before the operation could complete.

    Declaration

    Swift

    case deadlineExceededError = 4

  • Indicates some requested entity (such as a file or directory) was not found.

    Declaration

    Swift

    case notFoundError = 5

  • Indicates that the entity a caller attempted to create (such as a file or directory) is already present.

    Declaration

    Swift

    case alreadyExistsError = 6

  • Indicates that the caller does not have permission to execute the specified operation.

    Declaration

    Swift

    case permissionDeniedError = 7

  • Indicates some resource has been exhausted, perhaps a per-user quota, or perhaps the entire file system is out of space.

    Declaration

    Swift

    case resourceExhaustedError = 8

  • Indicates that the operation was rejected because the system is not in a state required for the operation’s execution. For example, a directory to be deleted may be non-empty, an “rmdir” operation is applied to a non-directory, etc.

    Declaration

    Swift

    case failedPreconditionError = 9

  • Indicates the operation was aborted, typically due to a concurrency issue such as a sequencer check failure or a failed transaction.

    Declaration

    Swift

    case abortedError = 10

  • Indicates the operation was attempted past the valid range, such as seeking or reading past an end-of-file.

    Declaration

    Swift

    case outOfRangeError = 11

  • Indicates the operation is not implemented or supported in this service. In this case, the operation should not be re-attempted.

    Declaration

    Swift

    case unimplementedError = 12

  • Indicates an internal error has occurred and some invariants expected by the underlying system have not been satisfied. This error code is reserved for serious errors.

    Declaration

    Swift

    case internalError = 13

  • Indicates the service is currently unavailable and that this is most likely a transient condition.

    Declaration

    Swift

    case unavailableError = 14

  • Indicates that unrecoverable data loss or corruption has occurred.

    Declaration

    Swift

    case dataLossError = 15

  • Indicates that the request does not have valid authentication credentials for the operation.

    Declaration

    Swift

    case unauthenticatedError = 16

  • Indicates that audio record permissions were denied by the user.

    Declaration

    Swift

    case audioRecordPermissionDeniedError = 17

  • Audio record permissions cannot be determined. If this error is returned by Audio, the caller has to acquire permissions using AVFoundation.

    Declaration

    Swift

    case audioRecordPermissionUndeterminedError = 18

  • Indicates that AudioRecord is waiting for new mic input.

    Declaration

    Swift

    case audioRecordWaitingForNewMicInputError = 19

  • The first error code in MPPTasksErrorCode (for internal use only).

    Declaration

    Swift

    static var first: TasksErrorCode { get }

  • The last error code in MPPTasksErrorCode (for internal use only).

    Declaration

    Swift

    static var last: TasksErrorCode { get }
