iBeacon ranging broken in iOS 10.x

1

Just purchased an estimote development pack but the functionality with iOS 10.x appears to be broken for the past six months or more.
I configured everything to the book.
Region monitoring works.
Ranging fires once and then dies!
Tried the code on an iPad Air and an iPhone 5S, both behave in the same way.
Tried out the development portal; two example using your proximity library work… but I wait I want to know if I am immediate, near, far or in unknown here; as in Apple terminology? Will Estimote beacons work with the apple SDK? If not, how does this work if I have a mixture of beacons in use? We previously had radBeacons, which worked with the AppleSDK last time I checked.

Ok I found it! I was registering the same region twice! That was it, simply that. Here the sample code I used to find/test it ultimately. This works… credit needs to go to “Hacking with Swift” where the 90% of this code comes from.

import CoreLocation
import UIKit

class ViewController: UIViewController, CLLocationManagerDelegate {
@IBOutlet weak var distanceReading: UILabel!

var locationManager: CLLocationManager!

override func viewDidLoad() {
	super.viewDidLoad()

	locationManager = CLLocationManager()
	locationManager.delegate = self
	locationManager.requestAlwaysAuthorization()

	view.backgroundColor = UIColor.gray
            let b2S:beaconsT = beaconsT(bUUID: "B9407F30-F5F8-466E-AFF9-XXXX",bMajor: 54360,bMinor: 60020,bID: "beetroot")
            let b3S:beaconsT = beaconsT(bUUID: "5A4BCFCE-174E-4BAC-A814-XXXX",bMajor: 123,bMinor: 456,bID: "lemon")
            beacons2G.append(b2S)
            beacons2G.append(b3S)
}

override func didReceiveMemoryWarning() {
	super.didReceiveMemoryWarning()
	// Dispose of any resources that can be recreated.
}

func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) {
	if status == .authorizedAlways {
		if CLLocationManager.isMonitoringAvailable(for: CLBeaconRegion.self) {
			if CLLocationManager.isRangingAvailable() {
				startScanning()
			}
		}
	}
}

struct beaconsT {
    var bUUID:String
    var bMajor: CLBeaconMajorValue
    var bMinor: CLBeaconMinorValue
    var bID: String
}
var beacons2G:[beaconsT] = []

func startScanning() {
//		let uuid = UUID(uuidString: "5A4BCFCE-174E-4BAC-A814-092E77999999")!
//		let beaconRegion = CLBeaconRegion(proximityUUID: uuid, major: 123, minor: 456, identifier: "MyBeacon")
    for b2D in beacons2G {
        let uuid = UUID(uuidString: b2D.bUUID)!
        let beaconRegion = CLBeaconRegion(proximityUUID: uuid, major: b2D.bMajor, minor: b2D.bMinor, identifier: b2D.bID)
        locationManager.startMonitoring(for: beaconRegion)
        locationManager.startRangingBeacons(in: beaconRegion)
    }
}

func update(distance: CLProximity) {
	UIView.animate(withDuration: 0.8) { [unowned self] in
		switch distance {
		case .unknown:
			self.view.backgroundColor = UIColor.gray
			self.distanceReading.text = "UNKNOWN"

		case .far:
			self.view.backgroundColor = UIColor.blue
			self.distanceReading.text = "FAR"

		case .near:
			self.view.backgroundColor = UIColor.orange
			self.distanceReading.text = "NEAR"

		case .immediate:
			self.view.backgroundColor = UIColor.red
			self.distanceReading.text = "RIGHT HERE"
		}
	}
}

func locationManager(_ manager: CLLocationManager, didRangeBeacons beacons: [CLBeacon], in region: CLBeaconRegion) {
	if beacons.count > 0 {
		let beacon = beacons.first
		update(distance: (beacon?.proximity)!)
	} else {
		update(distance: .unknown)
	}
}
}
