Using the Roster Framework with SwiftUI

Updated: Mar 25, 2023

As developers, we’re always looking for ways to make our apps more efficient and organized. With the Roster framework, we can easily manage collections of objects in our SwiftUI apps. And don’t worry, I’ll be adding some light jokes to keep things interesting.

First things first, let’s talk about what the Roster framework is. Roster is a framework that allows us to manage collections of objects in a structured way. It provides a set of tools and APIs that allow developers to easily create and manage collections of objects, such as contacts, tasks, or events.

Here’s a little joke for you: Why do programmers prefer dark mode? Because light attracts bugs! Okay, maybe that was a bit of a stretch. Let’s get back to Roster.

To use Roster with SwiftUI, we need to create a Roster object and add objects to it. We can then use the RosterView to display the objects in our view hierarchy.

Here’s an example of how to use Roster in a SwiftUI app:

import SwiftUI
import Roster

struct Contact: Identifiable, Codable {
    let id = UUID()
    let name: String
    let email: String

class ContactStore: ObservableObject {
    @Published var contacts = Roster<Contact>()

struct ContentView: View {
    @ObservedObject var store = ContactStore()

    var body: some View {
        NavigationView {
            List(store.contacts.items) { contact in
            .navigationBarItems(trailing: Button(action: addContact) {
                Image(systemName: "plus")

    func addContact() {
        let contact = Contact(name: "John Doe", email: "")

In this example, we’re creating a Contact struct and a ContactStore class that contains a Roster of contacts. We're then using a List and a NavigationBar to display the contacts in our app.

And that’s it! With just a few lines of code, we’ve created a structured collection of objects and displayed them in our app.

In conclusion, the Roster framework is a powerful tool for managing collections of objects in our SwiftUI apps.

By using the Roster object and the RosterView, we can easily create a structured and organized app. And remember, even programming can be fun with a little bit of humor. Why did the programmer quit his job? Because he didn't get Roster!
