SwiftUI gets used a lot with Struct

SameID

This was avoided by regenerating the id with onDisappear.
If there is no change in @State, does that mean that you use the cache?
I'm going to learn more about it!

SameID

	import SwiftUI

	struct ContentView_20191114: View {
	@State var id = UUID().uuidString
	var body: some View {
	VStack {
	NavigationLink(destination: DetailView_20191114(hoge: Hoge(id: id))) {
	Text("Tap Me!")
	.font(.title)
	}
	}.onDisappear {
	self.id = UUID().uuidString
	}
	}
	}

	struct DetailView_20191114: View {
	var hoge: Hoge
	var body: some View {
	Text("id: \(hoge.id)")
	}
	}

	struct Hoge {
	var id: String
	}

	struct ContentView_20191114_Previews: PreviewProvider {
	static var previews: some View {
	ContentView_20191114()
	}
	}
