Swift is awful to use in practice. It once took me 24 hours to parse a JSON response into a Swift object. In ruby you can get a ruby object from JSON by calling JSON.parse(data)... that's it. It takes one second. In Swift it's a nightmare, it can take you a full day. Who the hell has time for that? Startups are all about speed, who wants to waste a day trying to parse JSON when it's a one-liner in literally every other language ever made. I also hate using mutable objects for my data model. Swift allegedly solves this with Structs but they're really hard to use in practice. Want to pass a struct through a Notification? Too bad, needs to inherit from NSObject so guess you're stuck using mutable objects? Swift might be a well designed language from an academic standpoint. I have no idea, I'm new to programming. But I can say for sure that it's horrible to use compared to other languages that I've used in production (Ruby, Clojure, Javascript). I would bet anything that being able to use any language/workflow of your choosing and compiling to iOS native through JS will be a better business decision than coupling yourself to XCode/Swift and whatever hacks you build to make the workflow less painful.
