struct FormatStyleStrategies for formatting a Date.
struct Symbolstatic let omitted: Date.FormatStyle.Symbol.YearThe option for not including the symbol in the formatted output.
static var twoDigits: Date.FormatStyle.Symbol.Year { get }Two low-order digits. Padded or truncated if necessary. For example, 02, 20, 01, 17, 73.
static func extended(minimumLength: Int = 1) -> Date.FormatStyle.Symbol.Year Extended year. This is a single number designating the year of this calendar system, encompassing all supra-year fields. For example, for the Julian calendar system, year numbers are positive, with an era of BCE or CE. An extended year value for the Julian calendar system assigns positive values to CE years and negative values to BCE years, with 1 BCE being year 0.
static func padded(_ length: Int) -> Date.FormatStyle.Symbol.Year Three or more digits. Padded if necessary. For example, 002, 020, 201, 2017, 20173.
static func relatedGregorian(minimumLength: Int = 1) -> Date.FormatStyle.Symbol.Year Related Gregorian year. For non-Gregorian calendars, this corresponds to the extended Gregorian year in which the calendar’s year begins. Related Gregorian years are often displayed, for example, when formatting dates in the Japanese calendar — e.g. “2012(平成24)年1月15日” — or in the Chinese calendar — e.g. “2012壬辰年腊月初四”.
