TableView does not show the header #100

Hi I'm getting, a weird behaviour using the lib, when I run the app I get the app with the table view set to 0,0 position of the screen. This problem is not happening on ios 13.2.1, it happens on earlier version. If I scroll down I can see the header view and it works as expected, the issue is that when it starts for the first time it is hidden.

This is the setup of my stretchy view:

    private let stretchyHeader: StretchyHeaderView = {
        let stretchyHeader = StretchyHeaderView(headerHeight: 350)
        stretchyHeader.expansionMode = .topOnly
        return stretchyHeader
    }()

I set it as subview of my table view in the viewDidLoad() method. The StretchyHeaderView is a custom subview where I setup a main image with auto layout, I use snapkit. The image is constrained to all the edges of the content view. If I inspect the view using the UI debugger I can see that the StretchyHeaderView has a weird value of height of -0.

Do you have any suggestions? Thanks.
