For a simple, resourceless cocoa apps I used to manually setup the application lifecycle (mimicking what's documented here: https://developer.apple.com/documentation/appkit/nsapplication), so my main.swift would look like:

import Cocoa

let delegate = SomeDelegate()
_ = NSApplication.shared
NSApp.delegate = delegate
NSApp.run()

This triggers a warning in Xcode 26.2: "Main actor-isolated conformance of SomeDelegate cannot be used in nonisolated context; this is an error in Swift 6 language mode".

so what is the recommended way to refactor above so that it is Swift 6 compliant?
