Two segmented controls using one action

Question

I have two separate segmented controls, both with the same segments. How can I set the second segmented control based on the first segmented control?

If the gallons segment is selected in the top segmented control, I want the bottom segmented control to automatically switch to gallons. Screenshot of the segmented controls

You can use something like:

segmentedControl1.addTarget(self, action: #selector(changeAction), forControlEvents: .ValueChanged)
func changeAction() {
    segmentedControl2.selectedSegmentIndex = segmentedControl1.selectedSegmentIndex
}
