Day 37 - Building a list we can delete from - Build Error [Entry point (_main) undefined. for architecture x86_64]

Hi there, I have having a problem with compiling the first part of this lesson at this point: https://youtu.be/2g1t15bwX44?t=337

I am recieving a Entry point (_main) undefined. for architecture x86_64 error.

I tried to add @main to my ContentView.swift code but that produced more errors.

All of the solutions to this error I can find online see to be for older versions of XCode / Swift.

I am trying to build foriPhone SE 3rd GenusingXCode 14.1 running Ventura 13.0.1 (22A400) on a MacBook Air Retina, 13-inch, 2020

Any ideas how to track this down? Thanks.

EDIT:

If I download project 7 from https://github.com/twostraws/HackingWithSwift there is a file in the project called iExpense.swiftthat contains:

import SwiftUI

@main
struct iExpenseApp: App {
    var body: some Scene {
        WindowGroup {
            ContentView()
        }
    }
}

When I add this file and code to my project it compiles.

However this doesn't seem to be in the tutorials at least not the first video? Or have I missed something?

when you created a new project did you delete any files? if you did you shouldnt, make a new project and follow the tutorial in ContentView. lmk if i understood badly

@Nanometer54 I don't believe I deleted anything. But I did get it working after adding the needed file / code.
