Mirroring or sharing your iPhone screen in a meeting

Five minutes before

1. Close the apps you won’t show. Swipe them away in the app switcher. The vault is already covered there. Sealed locks as soon as you leave it unless you choose a delay, and it covers its contents in the app switcher.
2. Turn off notifications for screen sharing. A message banner on a projector is read by everyone at once. The iPhone User Guide says they are allowed by default when you share your screen with SharePlay or Screen Mirroring; in Settings, Notifications, Screen Sharing, turn Allow Notifications off. It only applies while you share.
3. Lock the apps whose previews could appear. Apple lets you require Face ID, Touch ID or your passcode to open an app, and says information inside a locked app won’t appear in other places such as CarPlay, notification previews, search, Siri suggestions or your call history.
4. Look at your Home Screen. A Photos widget or a memory can put a personal photo on the wall. Photos can feature your photos in memories, in featured photos and in the Photos widget, and you can turn that off with Show Featured Content, under Collections and then your account button in Photos.
5. Check the AirPlay setting. Apple’s page says Automatically AirPlay can suggest or connect to devices you often use; set it to Ask or Never if a meeting room TV is one of them.

Starting

Apple says Screen Mirroring mirrors exactly what is on your screen. Open Control Center, tap Screen Mirroring, pick the TV or Mac, and enter the code if the screen shows one. On a video call, the call app’s own share button does the same thing.

Open the app you came to present before you start, not after.

While you share

• Stay in that app. Each switch shows the room your app switcher and your Home Screen.
• Don’t open Photos to “find that one picture”. The grid is the screen. The showing one photo page has better ways.
• If you open the vault by reflex, the room sees a cover, not your files. Sealed covers its contents while the screen is being recorded or mirrored, and that is on by default. Sealed’s cover follows what iOS reports as a captured screen: screen recording, AirPlay and wired mirroring, and screen sharing.

Ending

1. Stop mirroring right away. Open Control Center, tap Screen Mirroring, then Stop Mirroring (Apple).
2. Look at the TV before you leave the room, to be sure your screen is gone from it.

A habit for next time

What shows up uninvited is usually not an app you opened: it is a memory, a widget, a search suggestion, a shared album. The list of places private photos still show up covers them, and keeping photos out of Memories fixes the most common one.

Where Sealed helps, and where it doesn’t

It helps by covering its contents during mirroring and screen sharing. Sealed covers its contents while the screen is being recorded or mirrored, and that is on by default.

It helps by keeping private photos out of the grid you might open on stage. Sealed imports only the photos and videos you choose, and deletes the originals in Photos only when you ask.

It doesn’t cover other apps or silence their banners. Only its own screen goes blank. Sealed’s cover follows what iOS reports as a captured screen: screen recording, AirPlay and wired mirroring, and screen sharing.

It doesn’t block screenshots. Sealed warns you after you take a screenshot while a record’s values are showing, and it does not block screenshots.
