Swift ArgumentParser: Interactive mode

Hey @nnnnnnnn and Swift community!

I am Keith, a CS undergrad from the Hunan University of Technology. I've won Swift Student Challenge twice in WWDC20/21, and got the National Second Prize in Mobile Application Innovation Contest which hosted by Apple in China. I love Swift so much that I want to go deeper. So this year I hope to be involved in the GSoC project.

After reading the Command Line Interface Guidelines for the first time, I realized that part of the reason why the CLI of Unix, GitHub, Nvim can be so concise and elegant is their smooth interactivity. Swift as a cross-platform language also requires a more interactive user experience CLI tool. I think we can refer to pointfreeco's swift-parsing to interact with users by handling errors and and printing error messages.

Everyone is welcome to share thoughts, opinions and insights! :clap:

Best regards

Keith Bird

Anything that improves Swift for CLI tools is huge ^^

ArgumentParser has been a huge boost in this space, but I've long wanted to have something like Inquirer.js in Swift. Is this what you have in mind when you mention interactivity?
