# callAsFunction(id:)

Presents an immersive space for the scene with the specified identifier.

## Declaration

```swift
@discardableResult @MainActor func callAsFunction(id: String) async -> OpenImmersiveSpaceAction.Result
```

## Parameters

- `id`: The identifier of the immersive space to present.

## Discussion

Discussion Don’t call this method directly. SwiftUI calls it when you call the openImmersiveSpace action with a string identifier: await openImmersiveSpace(id: "planet") For information about how Swift uses the callAsFunction() method to simplify call site syntax, see Methods with Special Names in The Swift Programming Language.
