I had did beacon searching code as per Kontakt SDK Sample code as below. But I am getting beacon count always 0, while I am having 11 beacons near by my iPhone. Can any body help me over this?
I have initialise KTKBeaconManager in viewDidLoad method and then create region object and stopped any previous ranging service and then started new monitoring and ranging services.
And all time it calls didRangeBeacons with beacons count = 0. Not sure what exactly the issue. Its same code from their example code.
import UIKit
import KontaktSDK
class ViewController: UIViewController {
var beaconManager: KTKBeaconManager!
@IBOutlet var statusLabel: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
// Initiate Beacon Manager
beaconManager = KTKBeaconManager(delegate: self)
beaconManager.requestLocationAlwaysAuthorization()
// Region
let proximityUUID = NSUUID(uuidString: "f7826da6-4fa2-4e98-8024-bc5b71e0893e")
let region = KTKBeaconRegion(proximityUUID: proximityUUID! as UUID, identifier: "com.weenggs.KontaktDemo")
// Region Properties
region.notifyEntryStateOnDisplay = true
beaconManager.stopMonitoringForAllRegions()
// Start Ranging
beaconManager.startMonitoring(for: region)
beaconManager.startRangingBeacons(in: region)
beaconManager.requestState(for: region)
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
extension ViewController: KTKBeaconManagerDelegate {
func beaconManager(_ manager: KTKBeaconManager, didDetermineState state: CLRegionState, for region: KTKBeaconRegion) {
print("Did determine state \"\(state.rawValue)\" for region: \(region)")
statusLabel.text = "Did determine state \"\(state.rawValue)\" for region: \(region)"
}
func beaconManager(_ manager: KTKBeaconManager, didChangeLocationAuthorizationStatus status: CLAuthorizationStatus) {
print("Did change location authorization status to: \(status.rawValue)")
statusLabel.text = "Did change location authorization status to: \(status.rawValue)"
if status == .authorizedAlways{
// Region
let proximityUUID = NSUUID(uuidString: "f7826da6-4fa2-4e98-8024-bc5b71e0893e")
let region = KTKBeaconRegion(proximityUUID: proximityUUID! as UUID, identifier: "com.weenggs.KontaktDemo")
// Region Properties
region.notifyEntryStateOnDisplay = true
beaconManager.startMonitoring(for: region)
beaconManager.startRangingBeacons(in: region)
beaconManager.requestState(for: region)
}
}
func beaconManager(_ manager: KTKBeaconManager, monitoringDidFailFor region: KTKBeaconRegion?, withError error: Error?) {
print("Monitoring did fail for region: \(region)")
print("Error: \(error)")
statusLabel.text = "Monitoring did fail for region: \(region)"

}
func beaconManager(_ manager: KTKBeaconManager, didExitRegion region: KTKBeaconRegion) {
print("Did exit region \(region)")
statusLabel.text = "Did exit region \(region)"
}
func beaconManager(_ manager: KTKBeaconManager, didRangeBeacons beacons: [CLBeacon], in region: KTKBeaconRegion) {
print("Did ranged \"\(beacons.count)\" beacons inside region: \(region)")
statusLabel.text = "Did ranged \"\(beacons.count)\" beacons inside region: \(region)"
if let closestBeacon = beacons.sorted(by: { $0.0.accuracy < $0.1.accuracy }).first , closestBeacon.accuracy > 0 {
print("Closest Beacon is M: \(closestBeacon.major), m: \(closestBeacon.minor) ~ \(closestBeacon.accuracy) meters away.")
statusLabel.text = "\(statusLabel.text) Closest Beacon is M: \(closestBeacon.major), m: \(closestBeacon.minor) ~ \(closestBeacon.accuracy) meters away."
