UIPickerView get selected value without datasource

Question

What would be the best way to get the value from a PickerView without having a datasource? So i can not read values from i.e. an array.

Current values are just row numbers, that i need to read after user is done with picking.

func numberOfComponents(in pickerView: UIPickerView) -> Int {
    return 3
}

func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
    if component == 0 {
        return 300
    } else {
        return 10
    }
}

func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
    if component == 0 {
        return "\(row)."
    } else {
        return "\(row)"
    }
}

You can use pickerView.selectedRow(inComponent:)

let firstValue = pickerView.selectedRow(inComponent: 0)
let secondValue = pickerView.selectedRow(inComponent: 1)

Both will just be an Int value representing the currently selected row index in it's respective component. And since your values are starting from 0, you can use the values directly.
