thank you @tachyonics, needs a rebase (sorry)

also the sanity script is failing on some formatting issues, you should be able to run it locally or in docker

This is pretty cool, @tachyonics, I'm quite excited about this. I'm not a contributor to this library, but wanted to give this a try and provide some feedback.

I pulled this PR and have been running some tests, trying to learn how this works. I managed to get everything working with sam-deploy.sh, I can run the lambda and see data populated on DynamoDB. Pretty straight-forward.

However, I haven't been able to get it to work with deploy.sh. I manually configured AIM roles and permissions, but seems like I'm missing something. It woukld be great if README was updated with set up instructions.

Thank you!

Just got it working with deploy.sh, all I needed was to properly configure environment variables for the DynamoDB table I had granted permissions. Hoping this gets accepted (though more documentation would be great)

hi @tachyonics how do you want to proceed with this PR? note some thoughts about such additional examples in https://forums.swift.org/t/examples-and-getting-started-guides/

@tachyonics if you want to keep this around, could you please update this PR to be against the main branch so we can delete the old master branch
