在SwiftUI中，每隔24小时将变量值重置为0

import SwiftUI

struct ContentView: View {
    @State private var variable = 0
    
    var body: some View {
        Text("\(variable)")
            .onAppear {
                // 创建一个Timer，每隔24小时触发一次
                let timer = Timer(fire: Date(), interval: 24 * 60 * 60, repeats: true) { _ in
                    // 重置变量值为0
                    self.variable = 0
                }
                
                // 将Timer添加到RunLoop中
                RunLoop.current.add(timer, forMode: .common)
            }
    }
}

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