Is this good Combine Code?

Combine.swift

public func behindThePublisher(url: URL) -> AnyPublisher<NSAttributedString, Never> {
  /// …
} 

 class ActionViewController: UIViewController {

    @IBOutlet weak var textView: UITextView!
    var cancellables = Set<AnyCancellable>()

    @Published var displayText: NSAttributedString = NSAttributedString()

    func processURL(_ url: URL) {
        behindThePublisher(url: url)
            .sink { self.displayText = $0 }
            .store(in: &self.cancellables)
            /// I am storing the result in displayString, because I need it later
    }

    override func viewDidLoad() {
        super.viewDidLoad()

      // But so that the textView is automatically updated, I add a sink here
        $displayText
            .receive(on: DispatchQueue.main)
            .sink { value in
            self.textView.attributedText = value
        }
        .store(in: &cancellables)
      /// …
        processURL(url)
      /// …
    }
  }
