Fetching and displaying data from core data

Aim :

To be able to display the days selected and the time picked by the user in the same row of the table view. The time should appear at the top and the days selected should appear at the bottom, both in the same row, just like an alarm clock.

Work :

This is the relationship I've got setup :

and this is how I save the days that are selected from a UITable and the time from a UIDatepicker when the save button is tapped :

@IBAction func saveButnTapped(_ sender: AnyObject)
    {
        let context =  (UIApplication.shared.delegate as! AppDelegate).persistentContainer.viewContext //creates an object of a property in AppDelegate.swift so we can access it

        let bob = Bob(context: context)

        //save the time from UIDatePicker to core data
        let dateFormatter = DateFormatter()
        dateFormatter.dateFormat = "HH:mm"
        bob.timeToPing = dateFormatter.string(from: timePicked.date)

        // save the days selected to core data
        for weekday in filteredWeekdays
        {
            var day = Days(context: context) //create new Days object
            day.daysSelected = weekday as NSObject? //append selected weekday
            bob.addToTimeAndDaysLink(day) //for every loop add day object to bob object
        }

        //Save the data to core data
        (UIApplication.shared.delegate as! AppDelegate).saveContext()

        //after saving data, show the first view controller
        navigationController!.popViewController(animated: true)
    }

Now that the data is once saved, I get the data :

func getData()
{
    let context = (UIApplication.shared.delegate as! AppDelegate).persistentContainer.viewContext

    do
    {
        bobs = try context.fetch(Bob.fetchRequest())
    }
    catch
    {
        print("Fetching failed")
    }

}

Attempt to get the days selected :

I tried to follow this, the below comments and a formerly deleted answer to this question to do this :

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell
{
    let cell = UITableViewCell()

    let bob = bobs[indexPath.row]
    cell.textLabel?.text = bob.timeToPing?.description

    // retrieve the days that are selected
    var daysArray: [Days] = []
    daysArray = bob.timeAndDaysLink?.allObjects as! [Days]

    for days in daysArray
    {
        print (days.daysSelected?.description)
        cell.textLabel?.text = days.daysSelected! as! String

    }

    return cell
}

EDIT : print(daysArray) gives this :

[<Days: 0x6080000a5880> (entity: Days; id: 0xd000000000040000 <x-coredata://30B28771-0569-41D3-8BFB-D2E07A261BF4/Days/p1> ; data: <fault>)]

print(daysArray[0]) gives this :

<Days: 0x6080000a5880> (entity: Days; id: 0xd000000000040000 <x-coredata://30B28771-0569-41D3-8BFB-D2E07A261BF4/Days/p1> ; data: <fault>)

How to save days

let weekdays = ["Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday"]
var filteredWeekdays: [String] = []
 @NSManaged public var daysSelectedbyUser: NSSet

And then

override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath)
    {
        selectedWeekdays()

    }

    override func tableView(_ tableView: UITableView, didDeselectRowAt indexPath: IndexPath)
    {
        selectedWeekdays()
    }

    func selectedWeekdays()
    {
        if let selectedRows = tableView.indexPathsForSelectedRows
        {
            let rows = selectedRows.filter {$0.section == 0}.map{ $0.row}
            filteredWeekdays = rows.map{ weekdays[$0] }
            print(filteredWeekdays)
        }
    }

Many thanks!
