struct FormatString

A type that represents a fixed date format string using string interpolation. Use `Date.FormatString` with ``Date/VerbatimFormatStyle`` or ``Date/ParseStrategy`` to create fixed-pattern format strings for dates. You build format strings using string interpolation with date field symbols: ```swift let format: Date.FormatString = "\(year: .defaultDigits)-\(month: .twoDigits)-\(day: .twoDigits)" ```
