Ask Siri to Find Your iPhone
With tvOS 12 you can also now ask Siri to find any of your other Apple devices — your iPhone, iPad, Apple Watch, AirPods, or even your MacBook.
Simply ask Siri to “find” the appropriate device and it will send a ping via iCloud to cause it to sound an alert, so you can figure out whether it’s slipped between the couch cushions or still sitting in your car.
