In the delegate method below, distance is of type Float:

Code Block func session(_ session: NISession, didUpdate nearbyObjects: [NINearbyObject]) {
    guard let object = nearbyObjects.first else { return }
     
    guard let distance = object.distance else { return }
     
    print("distance is of type Float but I need to convert to meters: ", distance)
}

How do I convert distance into meters so that I can find out exactly how far the peers are from one another?

I got the answer from here:

The distance is a Float type whose value is measured in meters:

Code Block func session(_ session: NISession, didUpdate nearbyObjects: [NINearbyObject]) {    
    guard let object = nearbyObjects.first else { return }         
    
    guard let distance = object.distance else { return } 
    let meters = String(format: "%.2f m", distance)
    print("meters: ", meters)
}
