I am currently trying to put a UITableView
in a different location rather than at the top of my view controller. With this said, it is trying to add the header
In My Case I had a UILabel under the UITableView in view hierarchy.
I moved it "forward" and the blank space appeared. Not sure why but it works like this, if theres anything under the tableView, it hides the blank space.
Also you can try checking/uncheking "Adjust Scroll View Insets" on your view controller inspector on storyboard.
