swift weird tableview scroll behaviour from tableView header section

Question

I have a weird tableview header behaviour when scrolling.

When I scroll up the header sticks on top of the view and a cell scrolls under the header.

If I scroll up more then the header starts scroll with the tableview.

Please have a look at GIF I added:

Set this in viewDidLoad() :

automaticallyAdjustsScrollViewInsets = false

And you can set content insets. Like this:

tableView.contentInset = UIEdgeInsets(top: <#T##CGFloat#>, left: <#T##CGFloat#>, bottom: <#T##CGFloat#>, right: <#T##CGFloat#>)
