SwiftUI:如何调用函数来填充LazyVGrid

import SwiftUI

struct ContentView: View {
    var body: some View {
        LazyVGrid(columns: [GridItem(.flexible(), spacing: 16)], alignment: .center, spacing: 16) {
            ForEach(generateViews(), id: \.id) { view in
                view
            }
        }
        .padding(.all, 16)
    }
    
    func generateViews() -> [CustomView] {
        var views: [CustomView] = []
        for i in 0..<20 {
            views.append(CustomView(id: i, title: "Item \(i)"))
        }
        return views
    }
}

struct CustomView: View {
    let id: Int
    let title: String
    
    var body: some View {
        VStack {
            Text(title)
                .font(.headline)
                .foregroundColor(.blue)
            RoundedRectangle(cornerRadius: 10)
                .fill(Color.gray.opacity(0.2))
                .frame(height: 100)
        }
        .frame(maxWidth: .infinity)
        .padding()
        .background(Color.white)
        .cornerRadius(10)
        .shadow(radius: 5)
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}

func generateViews() -> [CustomView] {
    var views: [CustomView] = []
    for i in 0..<20 {
        views.append(CustomView(id: i, title: "Item \(i)"))
    }
    return views
}

LazyVGrid(columns: [GridItem(.flexible(), spacing: 16)], alignment: .center, spacing: 16) {
    // 视图数组
}
