While using Messages on an iPhone that meets Share your screen.
You can jump from Messages to FaceTime to see another person’s screen, or even remotely control it.
Go to the Messages app iMessage. Shared playback controls keep everyone in sync.
In a supported app, find a show, movie, song, album, or other content you want to share, then tap the item to see its details.
Do one of the following:
Tap next to the content, then tap SharePlay.
In the To field, enter the contacts you want to share with, then tap Messages.
Tap Start or Play to begin using SharePlay.
To begin viewing or listening, recipients tap the content’s title at the top of the Messages conversation, then tap Open. For everyone who has access to the content, the video starts playing at the same time.
Note: If the shared content requires a subscription, the service may ask those who don’t have access to subscribe, make a transaction, or sign up for a free trial, if available.
When you select content to share and tap the Play button, you can also select Play for Everyone (if it appears) to begin it for everyone in the conversation. (Others on the thread may have to tap Join SharePlay to see the video.)
Each person in the conversation can use the playback controls to play, pause, rewind, or fast-forward for everyone, but settings like closed-captioning and volume are controlled separately by each person.
