struct ContentView: View {

        future = Calendar.current.date(byAdding: .second, value: (Int(seconds) ?? 0), to: future)! // also where is where im getting (cannot find 'seconds' in the scope)

        let date = Date.now...future

        let updatedDeliveryStatus = PizzaDeliveryAttributes.PizzaDeliveryStatus(driverName: "Anne Johnson", deliveryTimer: date)

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

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)

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

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)!

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
