weekdayName(), eraName(), quarterName() allows to specify locale overwrite to region's locale

[Pr-Chen]

My iPhone's language is Chinese, but when I run this code, weekdayName is english

guard let date = @"2017-12-29".date(format: .custom("yyyy-MM-dd"), fromRegion: Region.Local()) else {
    return
}

// name is Fri, but I expect is 周五
var name = date.weekdayShortName

Since SwiftDate 5.x you can use weekDayName function and you can override the current locale of the date (>=5.12):

let region = Region(calendar: Calendars.gregorian, zone: Zones.europeLondon, locale: Locales.chinese)
let date = "2017-12-29".toDate("yyyy-MM-dd", region: region)
let string = date?.weekdayName(.short, locale: Locales.english) // you can specify the output locale directly
