# getDomainsWithCompletionHandler(_:)

Returns all of the File Provider extension’s domains.

```

```swift
class func domains() async throws -> [NSFileProviderDomain]
```

## 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 domains() async throws -> [NSFileProviderDomain] For information about concurrency and asynchronous code in Swift, see Calling Objective-C APIs Asynchronously.
