Posted at

はじめに

ContextMenuは長押しした時に出るメニューです。
意外と知られてなさそうなので紹介します。

データ

struct Weather: Identifiable {
    let id = UUID()
    let iconName: String
    let iconColor: Color
    let title: String
}

let weathers: [Weather] = [
    .init(iconName: "sun.max.fill", iconColor: .orange, title: "晴れ"),
    .init(iconName: "cloud.fill", iconColor: .gray, title: "曇り"),
    .init(iconName: "cloud.rain.fill", iconColor: .blue, title: "雨")
]

実装

import SwiftUI

struct ContentView: View {
    var body: some View {
        List(weathers) { weather in
            Label {
                Text(weather.title)
            } icon: {
                Image(systemName: weather.iconName)
                    .foregroundColor(weather.iconColor)
            }
+           .contextMenu {
+               Button {
+                   print()
+               } label: {
+                   Text("テスト")
+               }
+           }
        }
        .listStyle(.grouped)
    }
}
