SwiftUI流 リアルタイム表示

Last updated at Posted at 2023-12-04

リアルタイムの日時を表示する記事をときどき見かけたので、SwiftUIしか知らない私なりのコードを残しておきます。

import SwiftUI

struct RealTimeView: View {
    @State private var date = Date.now

    private let timer = Timer.publish(
        every: 1.0,
        on: .main,
        in: .default)
        .autoconnect()

    private let format = Date.FormatStyle(
        date: .abbreviated,
        time: .standard)

    var body: some View {
        Text(date, format: format)
            .font(.title)
            .monospacedDigit()
            .onReceive(timer) { realDate in
                date = realDate
            }
    }
}

#Preview {
    RealTimeView()
}
