SwiftUI, Apple’s innovative and user-friendly UI framework, provides a way to build user interfaces across all Apple platforms with the power of Swift. One of its core components is Observable Objects, which play a critical role in managing the state of an app and updating the UI.
“The only way to do great work is to love what you do. If you haven’t found it yet, keep looking. Don’t settle.” — Steve Jobs
Let’s begin our journey by understanding the basics and gradually move towards advanced concepts.
What Are Observable Objects?
Observable Objects in SwiftUI are part of the data flow. They are used to notify views when there’s a change in the data they’re observing. To declare an Observable Object, we use the @Published and @ObservedObject property wrappers.
