Swift & Programmatically

class MyViewController: UIViewController, UITextFieldDelegate {

    let textFieldA = UITextField()
    let textFieldB = UITextField()
    let textFieldC = UITextField()
    let textFieldD = UITextField()

    var textFields: [UITextField] {
        return [textFieldA, textFieldB, textFieldC, textFieldD]
    }

    override func viewDidLoad() {
        // layout textfields somewhere 
        // then set delegate
        textFields.forEach { $0.delegate = self }
    }

    func textFieldShouldReturn(_ textField: UITextField) -> Bool {
        if let selectedTextFieldIndex = textFields.firstIndex(of: textField), selectedTextFieldIndex < textFields.count - 1 {
            textFields[selectedTextFieldIndex + 1].becomeFirstResponder()
        } else {
            textField.resignFirstResponder() // last textfield, dismiss keyboard directly
        }
        return true
    }
}
