@dynamicMemberLookup struct Triple

Helper for working with target triples.

@frozen struct Bool

A value type whose instances are either true or false.

init(_ description: String) throws

init(_ string: String, normalizing: Bool = false)

init(from decoder: Decoder) throws

static let macOS: Triple

static func getHostTriple(usingSwiftCompiler swiftCompiler: AbsolutePath) throws -> Triple

Determine the versioned host triple using the Swift compiler.

var _iOSVersion: Version { get }

Parse the version number as with getOSVersion. This should only be called with IOS or generic triples.

var _isSimulatorEnvironment: Bool { get }

If this is a Darwin device platform, should it be inferred to be a device simulator?

var _macOSVersion: Version? { get }

Parse the version number as with getOSVersion and then translate generic “darwin” versions to the corresponding OS X versions. This may also be called with IOS triples but the OS X version number is just set to a constant 10.4.0 in that case.

var _watchOSVersion: Version { get }

Parse the version number as with getOSVersion. This should only be called with WatchOS or generic triples.

let arch: Arch?

The parsed arch.

var archName: String { get }

var darwinLinkerPlatformVersion: Version { get }

var darwinPlatform: DarwinPlatform? { get }

Returns the DarwinPlatform for this triple, or nil if it is a non-Darwin platform.

var description: String { get }

var dynamicLibraryExtension: String { get }

The file extension for dynamic libraries (eg. .dll, .so, or .dylib)

var dynamicLibraryPrefix: String { get }

The file prefix for dynamic libraries

let environment: Environment?

The parsed Environment type.

var environmentName: String { get }

var executableExtension: String { get }

var isMacCatalyst: Bool { get }

var isWasm: Bool { get }

var nsbundleExtension: String { get }

The file extension for Foundation-style bundle.

let objectFormat: ObjectFormat?

The object format type.

let os: OS?

The parsed OS.

var osName: String { get }

Returns the name of the OS from the triple string.

var osNameUnversioned: String { get }

var osVersion: Version { get }

Parse the version number from the OS name component of the triple, if present.

var staticLibraryExtension: String { get }

The file extension for static libraries.

let subArch: SubArch?

The parsed subarchitecture.

let triple: String

The original triple string.

var tripleString: String { get }

let vendor: Vendor?

The parsed vendor.

var vendorName: String { get }

subscript(dynamicMember predicate: KeyPath<OS, Bool>) -> Bool { get }

Triple proxies predicates from Triple.OS, returning false for an unknown OS.

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

func encode(to encoder: Encoder) throws

func isAndroid() -> Bool

func isApple() -> Bool

func isDarwin() -> Bool

func isLinux() -> Bool

func isOpenBSD() -> Bool

func isRuntimeCompatible(with triple: Triple) -> Bool

Returns true if code compiled for triple can run on self value of Triple.

func isWindows() -> Bool

func platformName(conflatingDarwin: Bool = false) -> String?

The platform name, i.e. the name clang uses to identify this target in its resource directory.

func supports(_ feature: FeatureAvailability) -> Bool

Checks whether the triple supports the specified feature, i.e., the feature has been introduced by the OS and version indicated by the triple.

func tripleString(forPlatformVersion version: String) -> String

Returns the triple string for the given platform version.

func version(for compatibilityPlatform: DarwinPlatform? = nil) -> Triple.Version

Returns the OS version equivalent for the given platform, converting and defaulting various representations.

enum Arch

enum Environment

struct FeatureAvailability

Represents the availability of a feature that is supported on some platforms and versions, but not all. For Darwin versions, the version numbers provided should be the version where the feature was added or the change was introduced, because all version checks are in the form of tripleVersion >= featureVersion.

enum OS

enum ObjectFormat

enum SubArch

enum Vendor

struct Version

Represents a version that may be present in the target triple.
