Added accessories have no services available after adding services in HomeKit simulator?

So I'm trying to write a simple app to control my home kit devices, but I'm having trouble with the code.

Here is my code for browsing home kit accessories. But when I 

print(accessory.services.count)

I get 0. Here is some of my code:

import UIKit
import HomeKit

class DiscoveryTableViewController: UITableViewController, HMAccessoryBrowserDelegate {

//outlets
@IBAction func backButton(_ sender: AnyObject) {
    navigationController?.dismiss(animated: true, completion: nil)
}

@IBOutlet weak var saveButton: UIBarButtonItem!



let homeManager = HMHomeManager()
let browser = HMAccessoryBrowser()

var accessories = [HMAccessory]()
var selectedAcc: HMAccessory?

required init?(coder aDecoder: NSCoder) {
    super.init(coder: aDecoder)

    //setting the title to "Searching..."
    title = "Searching..."

    //setting the browser delegate = to self
    browser.delegate = self
    //searching for accessories
    browser.startSearchingForNewAccessories()

    //only searching for a short time to be efficient
    Timer.scheduledTimer(timeInterval: 5.0, target: self, selector: #selector(DiscoveryTableViewController.stopSearching), userInfo: nil, repeats: false)


}



func stopSearching() {
    title = "Discovered"
    browser.stopSearchingForNewAccessories()
}


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

// MARK: - Table view data source

override func numberOfSections(in tableView: UITableView) -> Int {
    // #warning Incomplete implementation, return the number of sections
    return 1
}

override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    // #warning Incomplete implementation, return the number of rows
    return accessories.count

}


override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cellIdentifier = "DiscoveryTableViewCell"
    let cell = tableView.dequeueReusableCell(withIdentifier: cellIdentifier, for: indexPath) as! DiscoveryTableViewCell
    let accessory = accessories[(indexPath as NSIndexPath).row] as HMAccessory

    // Configure the cell...
    cell.discNameLabel.text = accessory.name

    //print(accessory.services.count)

    return cell
}

override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    selectedAcc = accessories[indexPath.row]
    performSegue(withIdentifier: "showDeviceDetail", sender: self)
    //performSegue(withIdentifier: "UnwindToDeviceTable", sender: self)
}


override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
    if segue.identifier == "showDeviceDetail" {
        if let destination = segue.destination as? AddDeviceViewController {
            destination.addedAcc = selectedAcc
        }
    }
}


// Informs us when we've located a new accessory in the home
func accessoryBrowser(_ browser: HMAccessoryBrowser, didFindNewAccessory accessory: HMAccessory) {
    accessories.append(accessory)

    //PRINTING SERVICES.COUNT
    print(accessory.services.count)
    tableView.reloadData()
}



func accessoryBrowser(_ browser: HMAccessoryBrowser, didRemoveNewAccessory accessory: HMAccessory) {
    var index = 0
    for item in accessories {
        if item.name == accessory.name {
            accessories.remove(at: index)
            break; // done
        }
        index += 1
    }
    tableView.reloadData()
}


}

In this class, I am browsing all my accessories. I can access all the names of all the devices, but when I print the "services.count", I get 0 every time. Can someone help? And yes I have added services and characteristics under each accessory in the HomeKit simulator.

I just confirmed this, services are not available until after you add an accessory to a home, which implies that you have paired with the accessory: 

homeManagerInstance.primaryHome?.addAccessory(accessory, completionHandler: { (error) in
   print("ACCESSORY SERVICES: \(accessory.services.count)")
})

If you try to check service.count before that, it does indeed come back as zero.
