I'm using RestKit and was wondering how to combine two array's into one array.

I already have the data being pulled in separately from API1 and API2, but I don't know how to combine them into 1 tableView.

Each API is pulling in media, and I want the combined tableView to show the most recent media (like any standard timeline does these days).

I will post any extra code or help as necessary, thanks so much!

Below shows API1 + API2 being pulled in correctly, but not combined into the tableView. Only data from API1 shows in the tableView.
