Why is this not working?

Test.swift

import SwiftUI
import PlaygroundSupport

struct TestView: View {
    @State var foo = "faz"
    init() {
        foo = "bar"
        debugPrint(foo) // prints "faz"
    }
    var body: some View { Text(foo) }
}

PlaygroundPage.current.setLiveView(TestView())
// Result: faz is displayed
