# init(to:allowedFields:maxFieldCount:thresholdField:)

Creates a format style that refers to a comparison date using natural language.

## Declaration

```swift
init(to date: Date, allowedFields: Set<Date.RelativeFormatStyle.Field> = [.year, .month, .day, .hour, .minute], maxFieldCount: Int = 2, thresholdField: Date.RelativeFormatStyle.Field = .day)
```

## Parameters

- `date`: The date this format references.
- `allowedFields`: The units of time that may appear in the relative representation. The style always includes the thresholdField regardless of this set.
- `maxFieldCount`: The maximum number of fields the style shows in the absolute representation. The style excludes more significant fields whose value matches the reference date, making room for less significant ones.
- `thresholdField`: The time unit that tells the style when to switch from relative to absolute representation. For example, if you provide .minute and the time difference extends to hours or days, the style switches from relative to absolute.
