Platform security patterns

Each Apple platform handles security differently based on its use context while maintaining a consistent foundation of user privacy and data protection.

Security approaches:

• macOS: Controls how apps can access files and features. Each app runs in its own protected space, like a container, that limits what it can do without user permission. Apps need explicit approval to access files, the camera, or other sensitive features.
• iOS/iPadOS: Uses strict app isolation for protection. Each app can only access its own data and must ask users for permission to use features like camera, location, or contacts.
• visionOS: Adds spatial privacy considerations. Apps need permission to scan the room or track hand movements, ensuring users know what apps can see about their space.
• watchOS: Simplifies security through iPhone connection. Apps get their main permissions from paired iPhones while keeping sensitive data protected.
