I'm trying to display a list of different times that could have different time zones. I have created a Model that includes an ID = UUID(), name: String, time: Date, and localTimeZone: TimeZone.

Ideally, I'd like to either create a new or change the timezone of an existing dateformatter for every item in the list. Here is the framework of code I am trying to get working:

Thank you, I appreicate any tips and suggestions.

import SwiftUI

struct ExampleModel: Identifiable {
    var id = UUID()
    var name: String
    var date: Date
    var localTimeZone: TimeZone
}

let sampleData = [

    ExampleModel(name: "Name 1", date: dateFormatter.date(from: "02:00L")!, localTimeZone: TimeZone(abbreviation: "PST")!),
    ExampleModel(name: "Name 2", date: dateFormatter.date(from: "05:17L")!, localTimeZone: TimeZone(abbreviation: "EST")!),
    ExampleModel(name: "Name 3", date: dateFormatter.date(from: "18:33L")!, localTimeZone: TimeZone(abbreviation: "GMT")!)
]

let dateFormatter: DateFormatter = {
    let formatter = DateFormatter()
    formatter.dateFormat = "HH':'mm'L'"
    formatter.timeZone = TimeZone(secondsFromGMT: 0)
    return formatter
}()

struct DateFormatterTest: View {
    var exampleData: [ExampleModel]

    var body: some View {
        List(sampleData) { item in
            HStack {
                Text(item.name)
                //dateFormatter.timeZone = item.localTimeZone------------//
                Text(dateFormatter.string(from: item.date)) //Display this in local time.
            }
        }
    }
}

struct DateFormatterTest_Previews: PreviewProvider {
    static var previews: some View {
        DateFormatterTest(exampleData: sampleData)
    }
}

Thanks again, Jacob

Got it!

I created a 'func' to run the code I needed to create a DateFormatter and return a String, then called it in the view. So simple, but for a new guy it took a while.

Thanks to this video for giving me the idea: https://www.hackingwithswift.com/books/ios-swiftui/calculating-the-total-per-person

I'll be making some final tweeks for my actual project, here's how I made it work:

...
let dateFormatter: DateFormatter = {
    let formatter = DateFormatter()
    formatter.dateFormat = "HH':'mm'Z'"
    formatter.timeZone = TimeZone(secondsFromGMT: 0)
    return formatter
}()

struct DateFormatterTest: View {
    var exampleData: [ExampleModel]

    var body: some View {
        List(sampleData) { item in
            HStack {
                Text(item.name)
                //dateFormatter.timeZone = item.localTimeZone------------//
                Text(dateFormatter.string(from: item.date)) //Display this in local time.
                Text(getTimeFormatted(time: item.date, timeZone: item.localTimeZone))
            }
        }
    }
}

func getTimeFormatted (time: Date, timeZone: TimeZone) -> String {
    let timeFormat = DateFormatter()
    timeFormat.dateFormat = "HH':'mm'L'"
    timeFormat.timeZone = timeZone
    return timeFormat.string(from: time)
}
...
