How to parse JSON before application starts loading?

Question

iOS

I can't figure out the next one.
There is a ViewController and an object lies on it, say tableView.
I'm fetching a list from the server that I need to reflect in this table.
But the problem is that the method that receives the JSON and parses it is called by the application AFTER all the table protocol methods (Sourse and Delegate) are called). Accordingly, nothing is loaded into the table, since there is nothing to load.
How to deal with the problem?
Thank you!

Answer 1

tableView.reloadData()
in the callback of the method that receives the data
