Apple Watch helps users access information quickly, but sometimes they may want to dive deeper into content on their other devices. Your watchOS app uses Handoff to convey information about the user’s current activity to their other devices.

On iOS, users initiate Handoff by swiping up on your app icon on the device’s lock screen. When your iOS app receives a Handoff request, it uses the provided information to continue the task that was initiated on Apple Watch.
