# init(matchDomains:andAction:)

Initialize an NEEvaluateConnectionRule instance with a list of destination host domains and an action.

## Declaration

```swift
init(matchDomains domains: [String], andAction action: NEEvaluateConnectionRuleAction)
```

## Parameters

- `domains`: An array of domains used to match the destination hostname of connections. If the destination hostname of a connection matches any of the domains in the array, then the connection matches the rule. Each domain is matched against the destination hostname using suffix matching, and each label in the domain must match an entire label in the hostname. For example, the domain example.com will match the hostname www.example.com but not www.anotherexample.com.
- `action`: The action to apply for connections matching the rule.
