ios – Capturing person enter knowledge in a UITextField

I created 2 UITextFields for the person to enter knowledge (Int) into. I then need to create a var from the person enter knowledge to make use of in some equations. How do I am going about recording the info that the person inputed into the blocks?

My code presently appears to be like like this.

import UIKit

class ViewController: UIViewController {
    override func viewDidLoad() {
        tremendous.viewDidLoad()
              
        let faucet = UITapGestureRecognizer(goal: self, motion: #selector(UIInputViewController.dismissKeyboard))

        view.addGestureRecognizer(faucet)
    }

    @objc func dismissKeyboard() {
        view.endEditing(true)
    }

    @IBAction func sMinInput(_ sender: UITextField) {
        
    }
    
    @IBAction func sMaxInput(_ sender: UITextField) {
        
    }
