Swift 2 - UIPickerView values of two components

I have a UIPickerView with two components, when I change component[0] the data of thecomponent[1]` is reloaded.

Now I am trying to get the values of both components in one string using didSelectRow however, I cannot get the result I want.

public func pickerView(pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {

        if component == 0 {

            String0 = arr0[row]
            pickerView.reloadComponent(1)

        }
        if component == 1{

        String1 = arr1[row]

        }

        print("\(String0), \(String1)")

        // result: " , string1.value"
    }

When I select component[0] the result changes but only for String0 What i am trying to achieve is to get "string0.value, string1.value"

You can use method selectedRowInComponent to get the selected row in each component, The selected row would be your correct index to form the string.

Try:

public func pickerView(pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {

    if component == 0 {
        pickerView.reloadComponent(1)

    }
    String0 = arr0[pickerView.selectedRowInComponent(0)]
    String1 = arr1[pickerView.selectedRowInComponent(1)]

    print("\(String0), \(String1)")

    // result: " , string1.value"
}
