Code Highlights

Managing State with @State

State variables are used to dynamically update the UI when the data changes.

@State private var groceries: [String] = ["Apples", "Bananas", "Carrots"]

Dynamic Lists with ForEach

Generate UI elements dynamically from an array.

List {
    ForEach(groceries, id: \ .self) { item in
        Text(item)
    }
    .onDelete(perform: deleteItem)
}

Navigation with NavigationStack

Enable navigation between screens easily.

NavigationStack {
    NavigationLink("Add Grocery", destination: AddGroceryView())
}

Styling Components

Apply custom styles to elements for a polished look.

Text("Welcome to Grocery App")
    .font(.largeTitle)
    .foregroundColor(.blue)
