Hey Ankur, WOW — Thank you so much for the kind words :) It’s a pleasure getting such positive feedback for my writing and even more awesome to hear it helped you. Thanks for share()ing (lol) that with me!

Regarding Combine and a Book, I’m actually one of the authors on the new Combine book by raywenderlich.com and I wrote some of the operators chapters there as well. Maybe you’ll find it interesting, check it out: https://bit.ly/getcombinebook
