Just out of curiosity what kind of network activity causes the spinner in the status bar to spin? It never spins in my app even when data is being fetched. In Instagram, it always spins when data is being fetched.
Edit: To clarify that this question is not a duplicate. I am wondering what makes the loading indicator appear in the status bar, not just how to make it appear. Is it common to call UIApplication.shared.isNetworkActivityIndicatorVisible = true every time a call is made to the server?
