Opens a new window with the desired webpage.

## Declaration

```

```swift
class func openWindow(with url: URL) async -> SFSafariWindow?
```

## Parameters

- `url`: The URL to navigate to. The URL scheme must be http or https.
- `completionHandler`: A block to call when the URL is loaded in a new window.

## Discussion

Discussion important: You can call this method from synchronous code using a completion handler, as shown on this page, or you can call it as an asynchronous method that has the following declaration: class func openWindow(with url: URL) async -> SFSafariWindow? For information about concurrency and asynchronous code in Swift, see Calling Objective-C APIs Asynchronously.
