struct LanguageCodeimport 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.
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.

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.
