MVVM Design Pattern Using Swift in iOS

Learn to build a good news iOS app with a dynamic feed of large and small custom cells, each displaying a title and description, implemented using the MVP design pattern.

Register for a free News API developer account to obtain your API key, then use the top headlines endpoint (US) to fetch articles in JSON for your MVVM iOS project.

Set up and configure an iOS user interface using a table view controller and navigation controller, apply large titles, and customize the navigation bar appearance for a polished news list.

Build a web service with get articles that fetches top headlines from news api.org via URLSession dataTask, returning articles through a completion handler.

Create an article view model to display a single article and a parent list view model to manage multiple articles; expose title and description and provide table view data access.

Create a custom self-sizing table view cell to display article title and description using a stack view and multi-line labels, with outlets for title and description.

Shows displaying news in an iOS app with MVVM, fetching articles via a web service, and populating a table view with article view models on the main thread.

Explore building a hot coffee ordering app using the MVVM design pattern, including adding orders, posting to a web API on Heroku, and displaying all orders in the UI.

Design an mvvm-based iOS interface using storyboard, create an orders table view controller and an add order view controller, embed in navigation controllers, and set up navigation and titles.

Learn to test a web api with Postman by posting a new order to a Heroku-hosted service and retrieving it with a get request. Set header to content-type: application/json.

Create a models folder and define an order model with name, email, coffee type, and size, using enums and codable for web service fetching and console display.

Test the web service by fetching coffee orders as an array of orders, decode them, and print the results to the console as a preparation for the view models.

Demonstrates displaying orders in a table view using mvvm, with an order list view model feeding order view models, mapping orders to cells showing type and size.

Master building an add coffee order screen with MVVM in Swift, populating coffee types and sizes via a CaseIterable enum and displaying them in a table view.

Enable single selection of a coffee type in a table view by tapping a row to display a check mark, restricting choices to cappuccino, latte, espresso, or cortado.

Learn to add new coffee orders to a table view using a delegate protocol, pass the order back to the orders list, and update the view model to refresh table.

Explore the OpenWeatherMap API for current weather data, sign up for an API key, and test city requests with unit options for Fahrenheit or Celsius.

Create a models folder and build a weather response using Codable to map the root json to a main weather structure, exposing temperature in kelvin and humidity for decoding.

Create a weather resource and fetch data from a weather API, decode JSON into models with a JSON decoder, and plan to move the service call into view models.

Implement the add weather view model to drive the add screen, construct a city weather URL, fetch and decode data via a weather resource, and return a weather view model.

Explore the starter project to see how the settings screen is wired with a settings bar button and a blank settings table view controller, preparing for Celsius or Fahrenheit options.

Implement a settings view model in mvvm using swift for iOS that exposes celsius and fahrenheit options via a unit enum, with display names and persistence through user defaults.

Demonstrates selecting and persisting a temperature unit (Celsius or Fahrenheit) in a settings table view using MVVM in Swift for iOS, with check marks and a done button updating temperatures.

Using the MVVM pattern in Swift for iOS, switch temperatures between Celsius and Fahrenheit by updating the weather list, converting values, and saving the last unit in user defaults.

Demonstrate view to view model binding in a standalone ui kit example, binding username and password fields to a login view model with a custom binding text field.

Learn view model to view binding in a login flow by updating username and password fields via a dynamic type and closures, with UIKit updates and SwiftUI alternatives noted.
