Is RxSwift for me? @ try! Swift NYC

It's difficult to make the jump from map and filter to say ... presenting view controllers or search bars that need to call an API on the web and populate a table view. To be honest, at first it seems almost like functional or reactive programming has nothing to do with UIKit or NSURLSession...

In this talk Marin (me) will show you how RxSwift (an async, event based framework) applies in few every day situations of the life of an iOS developer. If you like major pains being solved for you transparently at the price of a single dependance this talk is for you.
