Can you explain the concept of Binding in the context of programming?

In programming, Binding is the process of connecting data or objects together so that changes in one element automatically reflect in another.

In the context of iOS, Binding is often used to connect model data with interface elements, allowing the UI to update automatically when data changes without the need to manually update each element.

Example: Using @Binding in SwiftUI allows passing a reference to state from a parent component to a child, ensuring data synchronization.

struct ParentView: View {
    @State private var isOn = false

    var body: some View {
        ToggleView(isOn: $isOn)
    }
}

struct ToggleView: View {
    @Binding var isOn: Bool

    var body: some View {
        Toggle("Switch", isOn: $isOn)
    }
}

Here, changing the toggle in ToggleView will automatically update the isOn state in ParentView.
