LOL entering :gui when running the swift repl on the command line.

Trying to make some changes to a complex SQLite view that includes some custom functions. Unfortunately that means I can't just open the database in a GUI. I'm trying to "port" my functions to SQLite extensions using SQLiteExtensionKit but running into address boundary errors when loading the extension. Not really sure how to go about debugging the issue

"Frame vs Bounds"... One of the most asked iOS interview question!

📐 Frame → parent's coordinate system
🔲 Bounds → its own coordinate system
🔄 And what happens when you rotate a view?

When you have a shared resource in a multi-threaded environment, multiple queues can access to the same shared state. You need to use a mechanism for accessing the common resource synchronously. What do you do for synchronizing the access to the common resource?

The answer is here:

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.
