Created October 16, 2023 18:05
SwiftUI helpers to make dealing with ImmsersiveSpaces less annoying.
/// Create an ``ImmersiveSpaceState`` in your view, wrap it with `@State` and modify your view content with ``immersiveSpaceHelper()``.
/// Example:
/// ```swift
/// struct MyView: View {
/// @State
/// var immersiveSpaceState = ImmersiveSpaceState(id: "my-immersive-space-id")
///
/// var body: some View {
/// Toggle("Show/Hide Immersive Space", isOn: $immersiveSpaceState.show)
/// .immersiveSpaceHelper($immersiveSpaceState)
