API Call Data Issues with Passing to New View Controller - Swift - ios

Question

I am building a swift app and hit an issue where the data I get back from an API call is not being passed to the view controller. I have uilabels all over the page and they do not update after the query is made like I intended. I am trying to present the aviation weather data from the user on the view controller ReportViewController.
I can get the data to fill labels on the WxViewController, but don't understand why I can't mirror the same code to have it display on the ReportViewController instead. I have tried copy/paste and removing the same code from the WxViewController as well as having it in both places, but the only place that updates the label is WxViewController (testTextLabel). Any help getting out of this endless cycle would be appreciated!

Again, I really appreciate the help! There are no errors when I run my code.
