Learning Swift is definitely much easier in my opinion. There are some oddities though that come from the world of Objective-C, but I believe it's pretty easy to understand regardless.

Also something you need to keep in mind is that there is a lot of server-side infrastructure that handles these Social Media apps. The apps just serve up the content for the most part. The server-side aspect of things is doing all the interesting work.
