Implementing Proximity-Based Interactions Between Devices

Learn how to interact with a nearby device by measuring the distance between a watch and a paired iPhone.

Overview

• Note: This sample code project is associated with WWDC21 session 10165: Explore Nearby Interaction with Third-Party Accessories.

Configure the Sample Code Project

You can run this sample either in the simulator or on paired devices. When running on paired devices, both the watch and iPhone must contain the U1 chip.

To run on paired devices:

1. Select the WatchNIDemo target, then change the bundle ID to . Select the right team to let Xcode automatically manage your provisioning profile.
2. Repeat step 1 for the WatchKit app and WatchKit Extension target. The bundle IDs should be .watchkitapp and .watchkitapp.watchkitextension respectively.
3. Next, for the WatchKit app target, select the Info tab, and change the value of WKCompanionAppBundleIdentifier key to .
4. Finally, open the Info.plist file of the WatchKit Extension target, navigate to NSExtension > NSExtensionAttributes > WKAppBundleIdentifier key, and change the value of the key to .watchkitapp.
