struct ContentView: View {
    var body: some View {
        BeforeAfterSlider {

            Rectangle()
                .fill(.red.gradient)
                .overlay(Text("BEFORE").foregroundColor(.white))

            // After content
            Rectangle()
                .fill(.blue.gradient)
                .overlay(Text("AFTER").foregroundColor(.white))
        }
        .frame(height: 300)
        .clipShape(RoundedRectangle(cornerRadius: 12))
    }
}

Image Comparison

BeforeAfterSlider {
    Image("before_photo")
        .resizable()
        .aspectRatio(contentMode: .fill)
} afterContent: {
    Image("after_photo")
        .resizable()
        .aspectRatio(contentMode: .fill)
}
.frame(height: 400)

UI State Comparison

BeforeAfterSlider {
    // Loading state
    VStack {
        ProgressView()
            .scaleEffect(2)
        Text("Loading...")
            .font(.title2)
    }
    .frame(maxWidth: .infinity, maxHeight: .infinity)
    .background(.gray.opacity(0.3))
} afterContent: {
    // Loaded state
    VStack {
        Image(systemName: "checkmark.circle.fill")
            .font(.system(size: 80))
            .foregroundColor(.green)
        Text("Complete!")
            .font(.title2)
    }
    .frame(maxWidth: .infinity, maxHeight: .infinity)
    .background(.green.opacity(0.2))
}

Data Visualization Comparison

BeforeAfterSlider {
    BarChart(data: oldData, color: .red)
} afterContent: {
    BarChart(data: newData, color: .green)
}

System Images

BeforeAfterSlider {
    Image(systemName: "photo")
        .resizable()
        .aspectRatio(contentMode: .fit)
        .foregroundColor(.secondary)
} afterContent: {
    Image(systemName: "photo.fill")
        .resizable()
        .aspectRatio(contentMode: .fit)
        .foregroundColor(.primary)
}
.frame(height: 200)

🎯 Advanced Use Cases

Theme Comparison

BeforeAfterSlider {
    AppPreview()
        .preferredColorScheme(.light)
} afterContent: {
    AppPreview()
        .preferredColorScheme(.dark)
}

Performance Visualization

BeforeAfterSlider {
    LoadingSpinner(slow: true)
        .overlay(Text("Slow").foregroundColor(.red))
} afterContent: {
    LoadingSpinner(fast: true)
        .overlay(Text("Fast").foregroundColor(.green))
