What is phone screen sharing?

Phone screen sharing refers to the ability to share the screen of a phone with other devices or users. This can be particularly useful in various scenarios such as video conferencing, remote assistance, or collaborative work.

At WWDC, Apple introduced several enhancements and APIs related to screen sharing and screen capture:

ScreenCaptureKit: This kit allows apps to integrate with the system UI to share screens and video conference calls. It supports capturing high-quality streams, including HDR content, and provides a convenient recording API to capture screen, audio, and microphone content. For more details, you can refer to the session Capture HDR content with ScreenCaptureKit.
Enterprise APIs for visionOS: These APIs enable capturing and sharing the entire view inside Vision Pro, including the passthrough camera feed. This can be used for scenarios like a technician in the field sharing their view with an expert back at the office. The system's start broadcast button is used to initiate screen capture or sharing. For more details, you can refer to the session Introducing enterprise APIs for visionOS.
SharePlay on visionOS: SharePlay allows for shared experiences within FaceTime calls, creating a sense of presence with spatial Personas. This can be used to share app interfaces and collaborate in a shared virtual space. For more details, you can refer to the session Customize spatial Persona templates in SharePlay.

These enhancements make it easier to share screens and collaborate across different devices and platforms, providing a seamless and integrated experience.
