Refactoring the Location Cell View Model

Mastering MVVM with SwiftUI

With the WeatherService protocol in place, we can refactor the view models that need to provide their views with weather data. In this episode, we focus on the LocationCell by refactoring the LocationCellViewModel class.

Injecting Base URL and API Key

Mastering MVVM with SwiftUI

In the previous episode, we hard-coded the base URL and the API key of the Clear Sky API in the WeatherClient class. I'm not a fan of hard-coding configuration details. In this episode, we explore an alternative approach.

Fetching Weather Data

Mastering MVVM with SwiftUI

In this episode, we add the ability to fetch weather data from the Clear Sky API and decode a WeatherData object from the API response. We apply a pattern that should feel familiar by now.

Defining the Weather Data Model

Mastering MVVM with SwiftUI

It is time to focus on one of the core aspects of the weather application we are building, fetching and displaying weather data. Thunderstorm displays placeholder data for the time being. That is something we change in this and the next episodes.

Decoupling User Defaults

Mastering MVVM with SwiftUI

The user's defaults database acts as the store of the weather application we are building. That is fine, but most objects shouldn't be aware of that implementation detail. The LocationsViewModel and AddLocationViewModel classes are tightly coupled to the UserDefaults class, but that isn't necessary. In this episode, we decouple the LocationsViewModel and AddLocationViewModel classes from the UserDefaults class.

Updating Locations in User Defaults

Mastering MVVM with SwiftUI

In this episode, we revisit the addLocation(with:) method of the AddLocationViewModel class. In that method, the view model stores the location the user selected in the user's defaults database.

Persisting Locations in User Defaults

Mastering MVVM with SwiftUI

You may remember that the LocationsView displays a static list of locations. We need to change that if we want to put the AddLocationView to use. We keep it simple and store the list of locations in the user's defaults database. Let's get to work.

Bridging Passion and Profession

As developers, we spend countless hours glued to our screens, deeply immersed in lines of code. While the thrill of solving tough problems and building great software is undeniable, it's crucial to step away periodically and reconnect with something equally complex and rewarding. Nature.

Refactoring the Add Location View

Mastering MVVM with SwiftUI

In the previous episode, we declared the State enum. It defines the possible states of the AddLocationView. In this episode, we integrate the State enum into the AddLocationView.

A .gitignore for Swift Projects

I have been using the same .gitignore file for ages, making small changes as my needs changed over the years. In this episode, I walk you through the .gitignore file I use for Swift and Vapor projects.

Optimizing the User Experience

Mastering MVVM with SwiftUI

The user can add locations using the AddLocationView, but there is room for improvement. The user experience isn't optimal at the moment. The AddLocationView doesn't show a progress view when the application is forward geocoding the address the user entered and the user is faced with an empty view if no matches are found. That is something we address in this episode.

Improving the Testability of the Geocoding Client

Mastering MVVM with SwiftUI

In the previous episode, we made the Core Location framework a dependency of the project. That is fine, but we don't want a dependency to compromise the testability of the project. In this episode, we use a proven and familiar pattern to improve the testability of the GeocodingClient class.
