Understanding @EnvironmentObject in SwiftUI
When and How to Use It
SwiftUI is a declarative approach to building UI for Apple programs (notably iOS and MacOS) that simplifies state management across views.
One way we can manage state is through the @EnvironmentObject property wrapper, as we can share data easily across multiple views without the repetitive passing of data through every view layer.
So here is what @EnvironmentObject is, when it should be used, and how it can streamline data handling in any given SwiftUI app,
What is it?
EnvironmentObject is a property wrapper (so a type that wraps a given value in order to attach additional logic to it) that enables sharing of data from an object stored in the SwiftUI environment so data can be shared across a wide range of views.
So data can be managed in a way that makes it accessible and observable by multiple views, such as user preferences or app sessions.
Why Use @EnvironmentObject?
When EnvironmentObject is injected into a parent view, all views referencing this object will automatically update when the object’s properties change.
This has several advantages.
