Read Original

This technical article explains how to programmatically check if an iOS device is locked (a proxy for the screen being off). It covers using `UIApplication.shared.isProtectedDataAvailable` in the main app and details a workaround for app extensions using Keychain accessibility settings to infer the device's lock state. It includes steps for configuring Keychain sharing and code examples using a Keychain wrapper library.
