The concept of reactive programming can now be implemented using State variables that are Bindable in your application.
Or just one of those times when init() is not your friend
In this lesson we'll be going over how to present a modal along with passing Binding variables around our application. Lastly we also tackle the callback functionality of adding objects inside of our lists.
Generating dynamic lists and details screens from an API that returns JSON is a fairly common need in modern applications. In this video, we’ll show how to use URLSession to fetch JSON, decode it using JSONDecoder, and then use BindableObject and State properties to create a SwiftUI list from the results.
Binding is one of the several property wrappers that SwiftUI presents us to control data flow in the app. Binding provides us a reference like access to a value type. This week we will understand how and when to use binding. We will learn how to avoid common mistakes while using binding in SwiftUI.
When using object bindings there are two ever so slightly differently things we need to work with: the BindableObject protocol is used with some sort of class that can store data, and the @ObjectBinding property wrapper is used inside a view to store a bindable object instance.
...it’s time to touch the crucial aspect of every app, and it is data. All the apps have data to present or mutate. Data plays a vital role in apps using SwiftUI. Every view in SwiftUI is just a function of some state, where the state is our data.
