Developing Our First iOS App with React Native
Truthfully, the language barriers are <i>nothing</i> next to the API barriers dealing with your platform of choice.  I am probably giving away my age here, but there's very little that's new under the sun after you've tussled with... say one each of the big three language families.  These being: Nasty old C (not going anywhere, ever.  Deal with it.), modern scripting languages (Ruby, Python, et al) and the real deal functional languages (lisp, ml, haskell, etc).  It just turns into "Oh, this is how they handle an array.  Do I have any functional plumbing?  Ok, great.  How do I dispatch a thread? Ok, let's go."  It's just not that interesting after a while.<p>Objective-c is quirkier than most, swift is nice but still baking, but it really all boils down to the platform APIs.  And you're gonna have to get wet at a platform level if you want to provide functionality beyond a mobile web page.  (Albeit one with improved load times since it's coming from disk, at the cost of dynamic updates since it's coming from the app store.)
