Does Binding prevent redrawing the view

In the context of SwiftUI, a Binding does not inherently prevent a view from being redrawn. Instead, a Binding provides a two-way reference to a piece of state, allowing different views to share and update the same data. When the state that a Binding refers to changes, SwiftUI will automatically trigger a redraw of the view that depends on that state. This is part of SwiftUI's declarative nature, where views are automatically updated in response to state changes.
For example, in the session "SwiftUI essentials," it is explained that when a view's state changes, SwiftUI notices this change and calls the view's body again to update the UI. This means that while Binding facilitates data sharing and synchronization between views, it does not prevent redrawing; rather, it ensures that views are updated correctly when the underlying data changes.
If you are interested in more details about how Binding works in SwiftUI, you might want to check out the session SwiftUI essentials (12:29) where the concept of Binding and its role in state management is discussed.
