Nearby Interaction property supportsDirectionMeasurement returns false and NINearbyObject direction property is nil

Hello Theo_k, Thanks for posting this. Did it ever work on your 14 Pro Max? supportsDirectionMeasurement is returning true for me on iOS 18 with my iPhone 15 Pro Max. Does upgrading to iOS work for you? On our iPhone 16 Pro Max, it is returning false. Best, Ian

I'm having the same problem. iPhone 14 Pro, IOS26.2. I’d appreciate it if you could share it when you solve the problem.

Having the same problem, although I'm not sure if it's related to iOS26 or phones with the U2 chip. Worth noting that I am doing peer to peer rather then peer to object, but figured I'd share my findings.

iPhone 16 Pro (U2 chip), iOS 26.3.1:

NISession created — capabilities:
  token: true
  supportsDirection: false
  supportsCameraAssistance: true
  supportsExtendedDistanceMeasurement: true
  supportsPreciseDistanceMeasurement: true

iPhone 12 (U1 chip), iOS 18.6.2:

NISession created — capabilities:
  token: true
  supportsDirection: true
  supportsCameraAssistance: true
  supportsExtendedDistanceMeasurement: false
  supportsPreciseDistanceMeasurement: true

What I've found so far, at least the case of the 16 Pro / U2 / iOS 26 (?):

1. 3D direction vector is never available
2. Camera seems to be required for directional convergence
3. Everything seems to be determined by hAngle
4. Placing both a 16 Pro and a 12 face down on a table with rear cameras covered: 12 continues to show position with a dirSrc of '3D'; 16 Pro tells me to "Move to a brighter area" with a dirSrc of 'none'

iPhone 12 seems to start an NI session with hAngle as its dirSrc before resolving to 3D.

If anyone has experienced anything differently with NISessions, would love to hear it.
