## Discussion

Use this modifier to influence the appearance of system overlays
in your app. The behavior varies by platform. For an
[`ImmersiveSpace`](/documentation/SwiftUI/ImmersiveSpace), it affects the Home indicator.

> Note: You can indicate a preference with this modifier, but the system
> might or might not be able to honor that preference.

Affected non-transient system views can include, but are not limited to:

- The Home indicator.
- The SharePlay indicator.
- The Multitasking Controls button and Picture in Picture on iPad.
