One of the new features that iOS 15 offers is the ability to share your iPhone and iPad screen during FaceTime sessions so that you can enjoy films, music, and other media along with friends and family. This new feature, called SharePlay, has been included in iOS 15.1 and can now be used to a limited extent.
Currently, you can share content from Apple TV and Apple Music — as long as both of you are subscribers . You can share YouTube videos, HBO Max, Hulu, and Disney Plus as the list of shareable apps continues to expand.
