# url

The URL of the link that launched the App Clip.

## Declaration

```swift
var url: URL? { get }
```

## Discussion

Discussion Use url to retrieve data that’s passed to an App Clip on launch, and use the data to update the user interface of the App Clip. The value of url is the same as the NSUserActivity webpageURL property. If you don’t need to verify the user’s location when they launch your App Clip, use webpageURL instead.
