Hello everyone,
I want to create a NISession instance in my code but anywhere I call NISession() the simulator crashes with no error code. I followed the tutorial from apple about NearbyInteraction and downloaded their sample code and even there the NISession creation causes the app to crash. I updated my Mac to the latest version (Ventura 13.1) but this didn't fix the problem neither.
I hope you can help me.
I have the same issue. I am on Ventura 13.0.1 and Xcode 14.2. The sample code works for me when I use a simulator on iOS 15.5, but on iOS 16.2, it crashes immediately on NISession(). Here's my error stack:

I am so glad that I'm not the only one facing this problem
Did anyone figure this out? I'm having the same issue...
My simulator crashed for iPhone 14 Pro iOS 16.2 .. but when I installed iOS 15.5 and tried iPhone 13 Pro, it works! Try
I am also having this issue, has anyone found a solution.
Same here, also the sample project crashes at session = NISession() with EXC_BAD_INSTRUCTION (code=EXC_I386_INVOP, subcode=0x0). Worked before, now since using 16.2, it crashes.
I can confirm this is a bug introduced on iOS 16.1. Just ran tests using Xcode 14.2 and both 16.1 and 16.2 crash upon NISession() instantiation on the simulator.
Until this is fixed I suggest downloading simulators for iOS 16.0 and test there.
