Combine: Asynchronous Programming with Swift (First Edition)

The book is quite thick, it covers just about everything you need to know on Combine. It doesn't shy away from digging into details of the individual class implementations. It's driven by coding examples, but doesn't neglect explanation either ... the coverage is comprehensive.I can't complain about this one. And bear in mind... I gave ray 3 stars on his push notifications book. I don't just glow over whatever I read, this one they put effort into and it's good.

I think I am learning a lot from typing in the examples and understanding how they work. HOWEVER, there is no index, and there needs to be an index!! This is because 1) the Table of Contents is not enough, and, 2) there is so much information to absorb that I need to be able to go back and look up things that I am mis-remembering. For example, I know I read about .sink() in there somewhere, _but_where_?! (p. 287. Found it by flipping the pages for 10 minutes).Perhaps the authors could prepare an index and provide it to us as a .pdf or text file or online somehow. Please?
