DataLife is an observable data storage class


  • In ViewModel inherit from DataLifeViewModel and create a variable that will be the result value.
import DataLife

final class ViewModel: DataLifeViewModel {
    var myName = DataLife<String>()
    func fetchMyName() {
        myName.value = "Darth Vader"
  • In the ViewController you will call the variable that was created in the ViewModel that will be observed.
import UIKit

final class ViewController: UIViewController {
    @IBOutlet weak var nameLabel: UILabel!
    private let viewModel = ViewModel()
    override func viewDidLoad() {

    private func setupFetchMyName() {
    private func setupState() {
        viewModel.myName.observer(viewModel) { [weak self] name in
            self?.nameLabel.text = name
