Accessing Outlets from Different Files

I have a viewController with a bunch of labels. Each label has an outlet in that viewController.

I want the functions that operate on those labels to be in a different file. How do I access them?

Simplified example:

// File 1: VC1
class testScreen: UIViewController {

    @IBOutlet weak var myLabel: UITextField!

    override func viewDidLoad() {
        super.viewDidLoad()\
        
        formatLabel()
    }
}



// File 2: Functions

func formatLabel() {
    myLabel.backgroundColor = UIColor.green
}

(There are actually a lot of labels and fields and functions. I want to break everything up into small, manageable files.)

I'm not going to comment on the "best practices" to solve your organization problem, but according to your requirement, you would do this with extensions.

// File1.swift

class testScreen: UIViewController {

    @IBOutlet weak var myLabel: UITextField!

    override func viewDidLoad() {
        super.viewDidLoad()\
        
        formatLabel()
    }
}

// File2.swift

extension testScreen {
    func formatLabel() {
        myLabel.backgroundColor = UIColor.green
    }
}
