The session titled "What’s new in privacy" at WWDC 2024 covers several updates and features aimed at enhancing user privacy across Apple's platforms. Key highlights include:

• New Pickers: iOS 18 and macOS Sequoia introduce new pickers that allow users to share only the data they want, minimizing data sharing and avoiding unnecessary permission prompts. These pickers are designed to fit seamlessly into apps with customizable UI.

• App Group Container Protection: This feature extends sandboxing protections to shared containers for groups of apps, ensuring that data shared between apps remains protected. Prompts are shown when apps from other developers attempt to access shared containers.

• Local Network Privacy: Changes in local network privacy require apps to include a local network usage description to access certain network features. This is part of broader efforts to improve transparency and control over data access.

• Locked and Hidden Apps: A new system feature allows users to lock sensitive apps, providing peace of mind when sharing devices with others.

• Private Caller ID: Tools for implementing live caller ID without revealing sensitive information, using technologies like private information retrieval and homomorphic encryption.
