Backgrounding can leave private information in app-switcher previews. Assess screens containing balances or personal documents.
Evaluation approach
Use an appropriate cover during lifecycle transitions. Include multiple scenes and rapid switching.
Application example
A payment preview may need to hide recipient and amount. Recheck session state on return.
Limits and considerations
This does not establish prevention of every capture method.
Cover every scene
A cover added only to the main window may leave another scene exposed. Test rapid transitions and all active scenes. A cover that remains stuck or disappears before authorization is restored is also a defect.
Checks and decisions
- Test scene transitions
- Inspect previews
- Verify returning sessions
