Overview

DataLife is an observable data storage class

Usage

• 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() {
        super.viewDidLoad()
        
        setupState()
        setupFetchMyName()
    }

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