    Parameters

    detail

    The detail to place after description of the error description.

  • The object cannot be deleted.

    Declaration

    Swift

    case deleteFailed(detail: String)

    Parameters

    detail

    The detail to place after description of the error description.

  • The specified object already exists.

    Declaration

    Swift

    case duplicateObject(detail: String)

    Parameters

    detail

    The detail to place after description of the error description.

  • The directory URL cannot be retrieved.

    Declaration

    Swift

    case directoryURLNotAvailable

  • The directory URL with path cannot be retrieved.

    Declaration

  • Contents of directory cannot be retrieved.

    Declaration

    Parameters

    detail

    The detail to place after description of the error description.

  • The database cannot be retrieved.

    Declaration

    Swift

    case databaseNotAvailable

  • Use a representation that was unknown when this code was compiled.

    Declaration

    Swift

    case unknownRepresentation

Initializers

  • Creates a new instance with the specified raw value.

    If there is no value of the type that corresponds with the specified string value, this initializer returns nil.

    Declaration

    Swift

    init?(rawValue: Int)

    Parameters

    rawValue

    The raw value to use for the new instance.

Properties

  • The corresponding value of the raw type.

    Declaration

    Swift

    var rawValue: Int { get }

Equatable

  • Equality is the inverse of inequality. For any values a and b, a == b implies that a != b is false.

    Returns a Boolean value indicating whether two values are equal.

    Declaration

    Swift

    public static func == (lhs: ErrorProtocol, rhs: ErrorProtocol) -> Bool

    Parameters

    lhs

    A value to compare.
    rhs

    Another value to compare.

    Return Value

    true if the first argument equals the second argument; false if not.

Hashable

  • Hashes the essential components of this value by feeding them into the given hasher.

    Implement this method to conform to the Hashable protocol. The components used for hashing must be the same as the components compared in your type’s == operator implementation. Call hasher.combine(_:) with each of these components.

    Important

    Never call finalize() on hasher. Doing so may become a compile-time error in the future.

    Declaration

    Swift

    public func hash(into hasher: inout Hasher)

    Parameters

    hasher

    The hasher to use when combining the components of this instance.

CaseIterable

  • A collection of all values of this type.

    Declaration

    Swift

    public static var allCases: [ErrorProtocol] { get }

  • Setup entities before ErrorProtocol receives its first message.

    Declaration

    Swift

    public static func setupEntities()

CustomNSError
  • key

    The key of the error.

    Declaration

    Swift

    static var key: String { get }

  • The domain of the error.

    Declaration

    Swift

    static var errorDomain: String { get }

  • The error code within the given domain.

    Declaration

    Swift

    var errorCode: Int { get }

  • The user-info dictionary.

    Declaration

    Swift

    var errorUserInfo: [String : Any] { get }

LocalizedError

  • A localized message describing what error occurred.

    Declaration

    Swift

    var errorDescription: String? { get }

CustomStringConvertible

  • A textual representation of this instance.

    Declaration

    Swift

    var description: String { get }

CustomDebugStringConvertible

  • A textual representation of this instance, suitable for debugging.

    Declaration

    Swift

    var debugDescription: String { get }
