Oh this is useful, swift-argument-parser has an `AsyncParsableCommand` which is basically a drop-in replacement for `ParsableCommand` with async support!

Too bad it doesn't support `CommandConfiguration` 🥲

Today I've also learned you can rename your main.swift to something else and use the `@main` attribute on the struct conforming to `ParsableCommand`, instead of calling its `main` function.

I need to create a list of locations in a macOS app based on a partial string. For example, the user enters "salem" and the app returns a list of suggested cities that are named Salem. What are my options for getting a list of suggested locations based on a partial string? Is MKLocalSearchCompleter the best solution here or is there something newer I can use?

Do you know these spaghetti monsters? 🤔

They provide a very well explanation of how to terminate a Live Activity when the app is terminated in iOS concurrently here:
