How to draw over other apps with the iOS SDK

Android has a permission that allows apps to "draw over other apps" with floating content (using the SYSTEM_ALERT_WINDOW permission). Does iOS have anything similar?

While limited this is somewhat possible by using the Screen Time APIs and the ShieldConfigurationDataSource. There is not much to be customised, but technically and it is in overlay.

class ShieldConfigurationExtension: ShieldConfigurationDataSource {

let title = "ScreenBreak"
let body = "You have restricted usage of this application. Wait for the time limit to end."

override func configuration(shielding application: Application) -> ShieldConfiguration {
    // Customize the shield as needed for applications.
    return ShieldConfiguration(
        backgroundBlurStyle: UIBlurEffect.Style.light,
        backgroundColor: UIColor.gray,
        icon: UIImage(named: "sblogosmall.png"),
        title: ShieldConfiguration.Label(text: title, color: .white),
        subtitle: ShieldConfiguration.Label(text: body, color: .white),
        primaryButtonLabel: ShieldConfiguration.Label(text: "Close", color: UIColor.black),
        primaryButtonBackgroundColor: .white,
        secondaryButtonLabel: nil)
}

override func configuration(shielding application: Application, in category: ActivityCategory) -> ShieldConfiguration {
    // Customize the shield as needed for applications shielded because of their category.
    ShieldConfiguration()
}

override func configuration(shielding webDomain: WebDomain) -> ShieldConfiguration {
    // Customize the shield as needed for web domains.
    ShieldConfiguration()
}

override func configuration(shielding webDomain: WebDomain, in category: ActivityCategory) -> ShieldConfiguration {
    // Customize the shield as needed for web domains shielded because of their category.
    ShieldConfiguration()
}
}

No, this can't be done. A user can only interact with whatever app is currently in the foreground.
