Check the Device’s Supported Features

In iOS 16 and watchOS 9, check a device’s supported features with deviceCapabilities instead of calling this function.

The value of the supportsPreciseDistanceMeasurement device capability is equivalent to this property, as demonstrated in the following code.

var isSupported : Bool
if #available(iOS 16.0, watchOS 9.0, *) {
    isSupported = NISession.deviceCapabilities.supportsPreciseDistanceMeasurement
} else {
    isSupported = NISession.isSupported
}
if isSupported {
    // Initiate a nearby interaction session.
}
