You're joking? The idea is to take a topic with a lot of specific knowledge and build vertical search around it so you can go deeper on that topic. There exists an Awesome Swift, for example, with a lot of static data.

I'd like to build a search engine with all Swift urls and allow the user to make queries.

http://www.h4labs.com/dev/ios/swift.html

break out books, for instance.

When I get a few minutes, I'll add links to the source code for the books.

Show me SpriteKit articles within the past 30 days:
