Kind folks, Was all setup for online access to several Q&A sessions at this WWDC, even posted some questions. But other priorities on my project prevented me from attending. Did any of you hear any news on direction finding with 3rd party devices at this year's WWDC?

My current understanding is that (for iPhones later than 15) the NI framework returns null for direction. Apple recommends use of the ARkit in conjunction with NI (tech session way back in WWDC22!)

FYI, I've been trying hard to get any information on this topic. Would be happy to share what public information/speculation I've found (including how Apple get's such good range and direction info in their Find My app for their AirTag 2 😉). Perhaps we can set up a small discussion group for sharing insights and experiences with emerging UWB technology.

Comments appreciated.

You would want to watch the WWDC26 session Find your accessory with Bluetooth Channel Sounding which covers both Bluetooth and NI frameworks for finding devices.

Hey @makerdude,

I'm not as familiar with Nearby Interaction and the iOS side of things, but I did find that new in iOS 27.0 is Bluetooth Channel Sounding via the new init(bluetoothChannelSoundingIdentifier:previousBluetoothIdentifier:).

Since your question has the visionOS tag, I wanted to pop in to point out the improvements this year to object tracking on visionOS. Take a look at the session, Explore enhancements to visionOS object tracking to learn more about creating your own custom accessory to track.

Hope this helps,
Michael
