Lambda: There and Back Again by Rob Napier

Rob is a co-author of iOS Programming Pushing the Limits. Before coming to Cocoa, he made his living sneaking into Chinese facilities in broad daylight. Later he became a Mac developer for Dell. It's not clear which was the stranger choice. He has a passion for the fiddly bits below the surface, like networking, performance, security, and text layout. He asks `but is it good Swift?` a lot.

Abstract: I have been to Monad, to the Functor of Doom. I have seen the map, flattened and lensed. I have folded the infinite, lifted a Maybe, and I’d do it all over again. But from what I’ve seen, from Haskell to Church, we can rely on one truth, which is this: Swift is not a functional programming language. Pushing too hard to make it one fights Swift and breaks Cocoa.But Swift has absorbed some fantastic lessons from the functional world, and while value types may not quite be the present, they are clearly the future. We’ll explore how decades of work in functional languages have influenced Swift, and how you can use those features best while staying true to Swift, playing nice with Cocoa, and embracing Protocol Oriented Programming.
