SwiftUIで画面遷移時に値を渡す

September 13, 2020

SwiftUIで画面遷移時に値を渡す方法です。 ContentView ではフルーツの一覧を表示しています。フルーツが表示されたセルを押すと SecondView に遷移し、選択されたセルのフルーツ名が表示されます。

SwiftUI

	import SwiftUI

	struct ContentView: View {
	let fruits = ["Apple", "Banana", "Orange", "Grape", "Cherry", "Peach"]

	var body: some View {
	NavigationView {
	List(fruits, id: \.self) { fruit in
	NavigationLink(destination: SecondView(fruit: fruit)) {
	Text(fruit)
	}
	}
	}
	}
	}

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

	var body: some View {
	Text(fruit)
	}
	}

	struct SecondView_Previews: PreviewProvider {
	static var previews: some View {
	SecondView(fruit: "Apple")
	}
	}
