# Why Unlike Android, which provides built-in app switcher protection through the FLAG_SECURE window flag, iOS doesn't offer an official API to protect app content in the app switcher or background mode. This PR implements a custom solution that addresses this privacy gap. # How The feature uses iOS app lifecycle notifications (`willResignActive`/`didBecomeActive`) to automatically show/hide a configurable blur overlay when the app is inactive. It leverages `UIViewPropertyAnimator` for blur control and smooth animations, with blur intensity configurable from JavaScript via the Expo module bridge. # Test Plan To test this feature: Run the bare-expo app, navigate to the ScreenCapture screen, and enable "App Switcher Protection." Then, put the app in app switcher/background mode and verify that the screen is blurred. Next, disable the protection and put the app in app switcher/background mode again to confirm that the content is now visible. I've attached a screen recording of the testing process. https://github.com/user-attachments/assets/3d8d04cb-d57b-4d7e-849e-77dfde56b3ec # Checklist <!-- Please check the appropriate items below if they apply to your diff. --> - [ ] I added a `changelog.md` entry and rebuilt the package sources according to [this short guide](https://github.com/expo/expo/blob/main/CONTRIBUTING.md#-before-submitting) - [ ] This diff will work correctly for `npx expo prebuild` & EAS Build (eg: updated a module plugin). - [ ] Conforms with the [Documentation Writing Style Guide](https://github.com/expo/expo/blob/main/guides/Expo%20Documentation%20Writing%20Style%20Guide.md)
# Why When using `ScreenStackItem` with presentation `formSheet`, the `flex` does not work on iOS. This is a known issue in screens - https://github.com/software-mansion/react-native-screens/blob/main/ios/RNSScreen.mm#L182 This PR adds warning, so that users can more easily spot the issue. For example for this code: ```tsx <Modal presentationStyle="formSheet" .... style={{ flex: 1, justifyContent: 'center', alignItems: 'center', }}> ... </Modal> ``` The modal content will be placed at the top of formsheet, because `flex: 1` will not work. For this reason the warning will be displayed. <img height="512" alt="image" src="https://github.com/user-attachments/assets/2f5def04-afc7-4711-a341-8301a3f5b68a" /> # How 1. Flattening the styles for modal and checking for `flex`. This will not catch 100% of cases, but should be good for most. # Test Plan 1.
