SwiftUI - How to set color scheme only for specific tabs in TabView?

I have a TabView with two tabs, and I want the first tab to have color scheme of light and the second tab to have color scheme of dark.

I've tried this:

var body: some View {
    TabView {
        Tab("Tab 1", systemImage: "video") {
            FirstView()
                .preferredColorScheme(.light)
        }
        Tab("Tab 2", systemImage: "person") {
            SecondView()
                .preferredColorScheme(.dark)
        }
    }
}

Then I found that both tabs are in light scheme.

I've also tried this:

var body: some View {
    TabView {
        Tab("Tab 1", systemImage: "video") {
            FirstView()
        }
        Tab("Tab 2", systemImage: "person") {
            SecondView()
                .preferredColorScheme(.dark)
        }
    }
}

I found that at the beginning tab 1 is light, and when I switch to tab 2, tab 2 is dark, but then if I switch to tab 1 again, then tab 1 becomes dark!

So what should I do?

Answer

try this approach using a selectedTab, for example:

struct ContentView: View {
    @State private var selectedTab = 0  
    
    var body: some View {
        TabView(selection: $selectedTab) {  
            Tab("Tab 1", systemImage: "video", value: 0) { 
                FirstView()
            }
            Tab("Tab 2", systemImage: "person", value: 1) { 
                SecondView()
            }
        }
        .preferredColorScheme(selectedTab == 0 ? .light : .dark) 
    }
}
