# formatted() Formats the string using a localized hour-minute-second time pattern. ``` func formatted() -> String ``` ## Return Value A localized formatted string that describes the duration, such as `1:30:56` for a duration of 1 hour, 30 minutes, and 56 seconds in the U.S. English locale. In the Finnish locale, this returns `1.30.56`. ## Discussion The following example shows the effect of applying the default formatting to a duration of two seconds: ``` let duration = Duration.seconds(2) let formattedDuration = duration.formatted() // "0:00:02" ``` This method uses a default [`Duration.TimeFormatStyle`](/documentation/Swift/Duration/TimeFormatStyle). To modify the formatting, customize a [`Duration.TimeFormatStyle`](/documentation/Swift/Duration/TimeFormatStyle) or [`Duration.UnitsFormatStyle`](/documentation/Swift/Duration/UnitsFormatStyle), then call [`formatted(_:)`](/documentation/Swift/Duration/formatted(_:)) on the duration, passing in the style. You can also call `format(_:)` on the style, passing in a duration. --- Copyright © 2026 Apple Inc.
