Apps

My current apps and scripts for iOS and Mac. I welcome feedback on Twitter at @vandancd.

LearTheFlags for the iPhone

I set out to learn SwiftUI and also teach my son flags and capitals of the countries of the world. More about my journey into building this app on my blog.

Special thanks to Yohan Desai, Vijay Marolia and Karthik K for the motivaiton to build this app.

Learn the Flags is a simple app that helps you associate a country with its flag and learn some basic demographics about it like Capital, Continent it belongs to or how many neighbors it has and some more.

cURLTester

A simple cURL config file that allows you to get response headers and timing metrics in some well formatted and readable manner.

Download the file from GitHub.

Download the curl.cfg file to your local machine. Then run curl -K curl.cfg <host.domain.com>

Example:

curl -K curl.cfg https://www.vandan.co
