Last updated at Posted at 2020-05-26

起きたこと

NavigationViewが重なっちゃった!
スクリーンショット 2020-05-26 13.41.42.jpg

原因と対処法

NavigationViewが複数存在していることが原因です。
はじめのViewにのみNavigationView{}で囲むようにしましょう。

ソースコード

import SwiftUI

struct test12: View {
    var body: some View {
        NavigationView{   //これだけでいい
            NavigationLink(destination: test13()){
        Text("Hello, World!")
            }
        }
    }
}

struct test13: View {
    var body: some View {
        NavigationView {   //これはいらない
        NavigationLink(destination: test14()) {
        Text(/"Hello, World!")
        }
        }
    }
}
struct test14: View {
    var body: some View {
        
            
        Text("Hello, World!")
        
    }
}
struct test12_Previews: PreviewProvider {
    static var previews: some View {
        test12()
    }
}
