Using parse API in swift 3, only some query results are saving? - ios

Question

I'm new to Swift and programming. I'm using Xcode 8.2.1 and the Parse AWS (free) server.
I'm using the following Syntax in order to save all query results for specific object IDs in to one row of a new parse class.
Most of the query results are saving (e.g. primarycityquery, secondcityquery, citydetailsquery) but not all (e.g. multicityquery).
I'm using the exact same syntax in another UIViewController (with just 3 queries, though) and it's working fine.
Is the issue here that I'm running too many queries? This is all within viewDidLoad. Please advise if there is a better way to do this, as well.
Thank you!

Thank you. It does seem the magic number is 3. I've saved the values that were not saving in this view controller to another and then query them in one of my 3 queries here. All of my inputs are now successfully saved in one row of another class.
