SwiftUI创建字典以保存不同的视图

import SwiftUI

struct ContentView: View {
    @State private var selectedView: String = "view1"
    
    var body: some View {
        VStack {
            Picker("Select a view", selection: $selectedView) {
                Text("View 1").tag("view1")
                Text("View 2").tag("view2")
                Text("View 3").tag("view3")
            }
            .pickerStyle(SegmentedPickerStyle())
            
            getView(for: selectedView)
        }
    }
    
    func getView(for key: String) -> some View {
        let views: [String: AnyView] = [
            "view1": AnyView(Text("This is View 1")),
            "view2": AnyView(Image(systemName: "circle")),
            "view3": AnyView(Color.blue)
        ]
        
        return views[key, default: AnyView(EmptyView())]
    }
}

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