# NEURLFilter

A class used to voluntarily validate URLs for apps that don’t use WebKit or the URL session API.

## Declaration

```swift
class NEURLFilter
```

## Overview

Overview When using networking frameworks other than WebKit or Foundation’s URLSession, use the NEURLFilter API to evaluate URLs before potentially connecting to a restricted or malicious site. Call the class method verdict(for:) to check a URL and honor the “allow” or “deny” verdict. Don’t connect to any URL that receives a “deny” verdict.
