## Declaration

init(anchor: Date, allowedFields: Set<Date.AnchoredRelativeFormatStyle.Field>, presentation: Date.AnchoredRelativeFormatStyle.Presentation = .numeric, unitsStyle: Date.AnchoredRelativeFormatStyle.UnitsStyle = .wide, locale: Locale = .autoupdatingCurrent, calendar: Calendar = .autoupdatingCurrent, capitalizationContext: FormatStyleCapitalizationContext = .unknown)
```

## Parameters

- `anchor`: The date the formatted output is referring to.
