import FoundationEssentialsstruct LocaleLocale encapsulates information about linguistic, cultural, and technological conventions and standards. Examples of information encapsulated by a locale include the symbol used for the decimal separator in numbers and the way dates are formatted.
@frozen struct BoolA value type whose instances are either true or false.
init(components: Locale.Components) Creates a Locale with the specified locale components
init(from decoder: any Decoder) throws init(identifier: String) Return a locale with the specified identifier.
init(identifier: String, preferences: LocalePreferences?) init(languageCode: Locale.LanguageCode? = nil, script: Locale.Script? = nil, languageRegion: Locale.Region? = nil) init(languageComponents: Locale.Language.Components) Creates a Locale with the specified language components
static var autoupdatingCurrent: Locale { get }Returns a locale which tracks the user’s current preferences.
static var current: Locale { get }Returns the user’s current locale.
static var preferredLanguages: [String] { get }Returns a list of the user’s preferred languages.
static func canonicalIdentifier(from string: String) -> String Returns a canonical identifier from the given string.
static func canonicalLanguageIdentifier(from string: String) -> String Returns a canonical language identifier from the given string.
static func identifier(fromComponents components: [String : String]) -> String Constructs an identifier from a dictionary of components.
static func identifierDoesNotRequireSpecialCaseHandling(_ identifier: String) -> Bool var alternateQuotationBeginDelimiter: String? { get }Returns the alternate quotation begin delimiter of the locale.
var alternateQuotationEndDelimiter: String? { get }Returns the alternate quotation end delimiter of the locale.
var availableNumberingSystems: [Locale.NumberingSystem] { get }Returns all the valid numbering systems for the locale. For example, "ar-AE (Arabic (United Arab Emirates)" has both "latn" (Latin digits) and "arab" (Arabic-Indic digits) numbering system.
var calendar: Calendar { get }Returns the calendar for the locale, or the Gregorian calendar as a fallback.
var collation: Locale.Collation { get }Returns the default collation used by the locale. Default is .standard.
var collationIdentifier: String? { get }Returns the collation identifier for the locale, or nil if it has none.
var collatorIdentifier: String? { get }Returns the collator identifier of the locale.
var currency: Locale.Currency? { get }Returns the currency of the locale. Returns nil if the data isn’t available.
var currencyCode: String? { get }Returns the currency code of the locale.
var currencySymbol: String? { get }Returns the currency symbol of the locale.
var customMirror: Mirror { get }var debugDescription: String { get }var decimalSeparator: String? { get }Returns the decimal separator of the locale.
var description: String { get }var firstDayOfWeek: Locale.Weekday { get }Returns the first day of the week of the locale. Returns .sunday as the default value if the data isn’t available to the requested locale.
var forceHourCycle: Locale.HourCycle? { get }var forceMeasurementSystem: Locale.MeasurementSystem? { get }var forceTemperatureUnit: LocalePreferences.TemperatureUnit? { get }var groupingSeparator: String? { get }Returns the grouping separator of the locale.
var hourCycle: Locale.HourCycle { get }Returns the hour cycle such as whether it uses 12-hour clock or 24-hour clock. Default is .zeroToTwentyThree if the data isn’t available. Calling this on .current or .autoupdatingCurrent returns user’s preference values as set in the system settings if available, overriding the default value of the user’s locale.
var identifier: String { get }Returns the identifier of the locale.
var identifierCapturingPreferences: String { get }var language: Locale.Language { get }var languageCode: String? { get }Returns the language code of the locale, or nil if has none.
var measurementSystem: Locale.MeasurementSystem { get }var numberingSystem: Locale.NumberingSystem { get }Returns the numbering system of the locale. If the locale has an explicitly specified numbering system in the identifier (e.g. bn_BD@numbers=latn) or in the associated Locale.Components, that numbering system is returned. Otherwise, returns the default numbering system of the locale. Returns "latn" as the default value if the data isn’t available.
var prefs: LocalePreferences? { get }var quotationBeginDelimiter: String? { get }Returns the quotation begin delimiter of the locale.
var quotationEndDelimiter: String? { get }Returns the quotation end delimiter of the locale.
var region: Locale.Region? { get }Returns the region of the locale. For example, “US” for “en_US”, “GB” for “en_GB”, “PT” for “pt_PT”.

var scriptCode: String? { get }Returns the script code of the locale, or nil if has none.
var subdivision: Locale.Subdivision? { get }Returns the regional subdivision for the locale, or nil if there is none.
var temperatureUnit: LocalePreferences.TemperatureUnit { get }var timeZone: TimeZone? { get }var variant: Locale.Variant? { get }Returns the variant for the locale, or nil if it has none. For example, for the locale “en_POSIX”, returns “POSIX”.
var variantCode: String? { get }Returns the variant code for the locale, or nil if it has none.

Returns a localized string for a specified Calendar.Identifier.
func localizedString(forCollationIdentifier collationIdentifier: String) -> String? Returns a localized string for a specified ICU collation identifier.
func localizedString(forCollatorIdentifier collatorIdentifier: String) -> String? Returns a localized string for a specified ICU collator identifier.
func localizedString(forCurrencyCode currencyCode: String) -> String? Returns a localized string for a specified ISO 4217 currency code.
