im getting this error after this code, what module should Iimport here? or does it causes any other problem?

Sorry, but I still do not catch it.

I tested the following which works:

struct ContentView: View {
    let start = Date() 
    let future = Calendar.current.date(byAdding: .minute, value: 10, to: Date())!
    var deliveryTimer: ClosedRange<Date> {
        start...future
    }

    var body: some View {
            Text(timerInterval: deliveryTimer, countsDown: true)
    }
}

In the following

var future = Calendar.current.date(byAdding: .minute, value: (Int(minutes) ), to: Date())!

you use minutes. Where is the String minutes defined ?

if you change to

var future = Calendar.current.date(byAdding: .minute, value: 10, to: Date())!

That does work

That's normal as minutes and seconds are not defined anywhere.

What are the values you expect in them ? Where do you get those values ?

You should have something like:

struct ContentView: View {
    var minutes = "" // Or a computed var to get the value from somewhere
    var seconds = ""

    var body: some View {

Oh i must check the code

and I have clearly checked the code and here is my doubt

I have set deliveryTimer to be ClosedRange data format so to get ClosedRange input

so if I give Minutes and Seconds as variable it is showing error in Timer

I have added the code below which the data transfers from Content view to this view seeing this might give you a idea


import WidgetKit

import SwiftUI

import Foundation







struct dynamicIsland : Widget {

    

    var body: some WidgetConfiguration{

        ActivityConfiguration(for: PizzaDeliveryAttributes.self) { context in

            

            LockScreenLiveActivityView(context: context)

        } dynamicIsland: { context in

            DynamicIsland{

                

                DynamicIslandExpandedRegion(.leading){

                    Label("\(context.attributes.numberOfPizzas) Pizzas", systemImage: "bag")

                        .foregroundColor(.indigo)

                        .font(.title2)

                }

                DynamicIslandExpandedRegion(.trailing) {

Please format your code properly, without all those empty lines, it is so hard to read.

Does your code compile ? I get errors with Labels:

                        Label {
                            Text("\(context.attributes.numberOfPizzas) Pizzas")
                        } icon: {
                            Image(systemName: "bag")
                                .foregroundColor(.indigo)
                        }
                        .font(.title2)

Incorrect argument label in call (have '_:icon:', expected 'text:showIcon:')

Trailing closure passed to parameter of type 'String' that does not accept a closure

now check the code above also I have this in my contentview

  • Is it a new code ? What has changed ? Please, provide explanation, not only code. And once again, format properly, it is so hard to grasp your code as is.

inhave just added the code which caused the error label

    public typealias PizzaDeliveryStatus = ContentState
    public struct ContentState: Codable, Hashable {
        var driverName: String
        var deliveryTimer: ClosedRange<Date>
    }
    //var id = UUID()
    var numberOfPizzas: Int
    var totalAmount: String
    var orderNumber: String
}

i think i have a doubt in syntax only

i have used

Text(timerInterval: context.state.deliveryTimer, countsDown: true)

Where deliveryTimer is in ClosedRange Format like

var deliveryTimer: ClosedRange<Date>

Now if you go through this below code

   var future = Calendar.current.date(byAdding: .minute, value: (Int(minutes) ), to: Date())!
    future = Calendar.current.date(byAdding: .second, value: (Int(seconds) ), to: future)!    
    let date = Date.now...future
    let activityAttributes = PizzaDeliveryAttributes(numberOfPizzas: 10, totalAmount: "$100", orderNumber: "101")
    let initialContentState = PizzaDeliveryAttributes.ContentState(driverName: "Makwin", deliveryTimer: date )
    do {
        let deliveryActivity = try Activity<PizzaDeliveryAttributes>.request(attributes: activityAttributes, contentState: initialContentState,pushType: nil)
        print("Requested a pizza delivery Live Activity \(String(describing: deliveryActivity.id)).")
    } catch (let error) {
        print("Error requesting pizza delivery Live Activity \(error.localizedDescription).")
    }
}

now you may get some clearance of my doubt if i give value for minutes and seconds which is not defined in the code as Int or String it will not accept

do you know how to give input format for this Minutes and Seconds which is not defined in my code

var future = Calendar.current.date(byAdding: .minute, value: (Int(minutes) ), to: Date())!

future = Calendar.current.date(byAdding: .second, value: (Int(seconds) ), to: future)!
