Dismissing immersive views

BlockStack is now on Testflight! Try the game for free here.

When running an app that uses an immersive view, such as this Jenga demo, you might want the immersive scene to disappear when the window is closed. We can do this using the scenePhase environmental setting along with dismissImmersiveSpace.

For example, we can use the scenePhase value of the main content view to determine if it's been closed, and use that to hide the immersive view:

.onChange(of: showImmersiveSpace) { _, newValue in
    Task {
        if newValue {
            await showImmersiveView()
        } else if immersiveSpaceIsShown {
            immersiveSpaceIsShown = false
            await dismissImmersiveSpace()
        }
    }
}
.task(id: scenePhase) {
    switch scenePhase {
    case .inactive, .background:
        immersiveSpaceIsShown = false
        showImmersiveSpace = false
    default:
        break
    }
}

This onChange block will show the ImmersiveView if the newValue is true otherwise if the ImmersiveView is currently shown, it'll dismiss it.

Then the scenePhase task applies a switch to scenePhase that will update the showImmersiveSpace value to false when the window is closed or goes into the background. This would then result in the immersive view being dismissed.

Tracking on the ImmersiveView #

We can also keep track of whether the immersive view is showing by using scenePhase but applied to the RealityView in ImmersiveView:

.task(id: scenePhase) {
    switch scenePhase {
    case .inactive, .background:
        isShowingImmersive = false
    case .active:
        isShowingImmersive = true
    default:
        break
    }
}

Here a Binding of isShowingImmersive can be toggled and the system can be aware that the ImmersiveView has been dismissed.
