# domain

An NSString object containing the domain for the cookie.

## Declaration

```swift
static let domain: HTTPCookiePropertyKey
```

## Discussion

Discussion If this cookie attribute is missing, the domain is inferred from the value for NSHTTPCookieOriginURL. If you do not specify a value for NSHTTPCookieOriginURL, you must specify a value for NSHTTPCookieDomain.
