The first thing the system will do is present a permission prompt to both users. Say your app wants to run a Nearby Interaction session with another user's device. Let's start by talking about user control and transparency. So today, we are introducing the Nearby Interaction framework, a powerful yet easy-to-use interface to spatial awareness in iOS. We wanted to empower you to use such capabilities in your application. This sort of high-fidelity interactivity is only possible thanks to the Apple-designed U1 chip. The user can orient their device toward someone else's device to give a strong hint to the share sheet for presenting the most relevant sharing selection. The top selection that I'm highlighting here uses spatial sensing technologies available for the first time in the iPhone 11. Such understanding in a device you're holding in your hand can translate into fluid interactions with the environment. Spatial awareness, in essence, means understanding the physical world around you. Today we will talk about how to build a completely new class of user interactions that are based on spatial awareness in iOS. Hello and welcome to the session "Meet Nearby Interaction." My name is Yagil, and I'm an engineer from the Location team here at Apple.
