I used the Interface Builder to place a Switch object in a view. I ctrl dragged it into the Assistant to make its handler a method of the class the view's is in, which is itself a subclass of "UITableViewController". A dialog box appear into which I entered the function name, and select the the option to have the sender as an argument.
The result is function of the form:
@IBAction func switchStateChange(_ sender: UISwitch) {
}
Now I need to query this Switch's On/Off state from elsewhere in the program, and if necessary change its state. It is not a good solution to save the sender parameter to a global variable because then it would require the user to change this switch's state before that global variable is set.
What is needed is to identify, and lookup, this switch object to access it from anywhere in the application. How is this done?
