Boost Your App’s Performance with Lazy Stacks in SwiftUI

Did you know that improper use of SwiftUI stacks can lead to performance issues in your app? 🧐

When building scrollable layouts with VStack or HStack, you might notice lag or slow rendering when dealing with large data sets. That’s where Lazy Stacks come in!

Instead of rendering all views at once, LazyVStack and LazyHStack only create the views currently visible on the screen. This drastically improves memory usage and keeps your app smooth.

Here’s an example:

ScrollView {  
    LazyVStack {  
        ForEach(0..<1000) { index in  
            Text("Item \(index)")  
                .padding()  
                .background(Color.gray.opacity(0.2))  
                .cornerRadius(8)  
        }  
    }  
} 

✨ Why use Lazy Stacks?

Efficiency: Only the visible views are loaded into memory.
Scalability: Handle thousands of items seamlessly.
Flexibility: Works perfectly within ScrollView.
