Local notifications with repeat function for specific dates - ios

Question

I have time picker set up. Local notification takes time from the time picker and sends the notification.
I have three notification with identifiers notfica2, notifica3 and notifica 4.
Now, I want to repeat notifica 2 and notifica3 every weekday (Monday to Friday) and repeat notifica 4 every weekend (Saturday-Sunday).
I didn't pick dates for the notificas. So I think timePicker automatically picks the date the time was set.
Please show me how to implement this specific repeat option.
Also, I have another bug. Lets say when I am picking the time it is 5 pm. And I want to set time 3 pm for notifica2 and notifica3 (which I want to repeat every weekday)
The exception says negative time. I understand the issue but I need a fix. So, if I put 3 pm but its already 6 pm then the 3pm notification will be sent the next day if it is not Saturday or Sunday. Same with notifica 4. But instead this will shift by 5 days for next Saturday.
Here is my code so far.
This is a small part of a larger app.
var textfield: UITextField!
let timePicker = UIDatePicker()
let timePicker2 = UIDatePicker()
let timePicker3 = UIDatePicker()

//toolbar

timePicker3.datePickerMode = UIDatePickerMode.time
let toolBar = UIToolbar()
toolBar.sizeToFit()
//DoneButton
let doneButton = UIBarButtonItem(barButtonSystemItem: .done, target: nil, action: #selector (donePressed))
toolBar.setItems([doneButton], animated: false)
BWTimePicker.inputAccessoryView = toolBar
AWTimePicker.inputAccessoryView = toolBar
ODTimePicker.inputAccessoryView = toolBar
//Assigning timepicker to the text fields
BWTimePicker.inputView = timePicker
AWTimePicker.inputView = timePicker2
ODTimePicker.inputView = timePicker3
}
func donePressed(){
//Formatting the date.
let dateFormatter = DateFormatter()
dateFormatter.dateStyle = .none
dateFormatter.timeStyle = .short
// BWTimePicker.text = "\(timePicker.date)"
// AWTimePicker.text = "\(timePicker.date)"
// ODTimePicker.text = "\(timePicker.date)"
// self.view.endEditing(true)
if BWTimePicker.isEditing {
//do something to textfield1
BWTimePicker.text = dateFormatter.string(from: timePicker.date)
self.view.endEditing(true)
}
else if AWTimePicker.isEditing {
//do something to textfield2
AWTimePicker.text = dateFormatter.string(from: timePicker2.date)
self.view.endEditing(true)
}

}

let stringBW = BWTimePicker.text
let stringAW = AWTimePicker.text
let stringOD = ODTimePicker.text
//2. If the three time fields are not empty , we would send the notificaiton
