недопустимое соединение в моем проекте xcode с внутренним расположением estimote

Question

Я написал некоторый код и попытался сделать приложение, но у меня проблема: [CoreBluetooth] XPC-соединение недействительно. Я думаю, что мое мнение правильно соотносится с кодом. Я не знаю, где проблема. Сборка выполнена успешно, поэтому с кодом не должно быть проблем. Это мой первый раз с Xcode, Swift и MacBook, так что я действительно не ладил с этим.

import UIKit
class ViewController: UIViewController, EILIndoorLocationManagerDelegate {
    @IBOutlet weak var myLocationView: EILIndoorLocationView!

    var locationManager = EILIndoorLocationManager()
    var location: EILLocation!

    override func viewDidLoad() {
        super.viewDidLoad()

        self.locationManager.delegate = self

        let locationBuilder = EILLocationBuilder()
        locationBuilder.setLocationName("office")
        locationBuilder.setLocationBoundaryPoints([
            EILPoint(x: 0.00, y: 0.00),
            EILPoint(x: 0.00, y: 4.00),
            EILPoint(x: 4.48, y: 4.00),
            EILPoint(x: 4.48, y: 0.00)])

        locationBuilder.addBeacon(withIdentifier: "395b8767bd63efc0fff23894fa05cb0b",
