Add UITableView as viewForFooterInSection within a tableView - ios

Question

I'm trying to add a loop of custom UIViews at the end of a previous tableView so I have two consecutive lists inside the same VC.
As I wanted the scroll to be global and not into two separates tableViews I tried to add content with a loop inside viewForFooterInSection method.
As you can imagine it didn't go as planned. The debugger doesn't give me any errors but my UI does not show anything too. I'm wondering if someone would know how it could be achieved.
Here is a screen of what I want to do:
As you can see it should be two consecutive tableViews but I don't want them to be scrolling apart from each other. I want the flow of the page to be one big scroll.
Here is my code :
func tableView(_ tableView: UITableView, viewForFooterInSection section: Int) -> UIView? {
let footerView = UIView()
self.getBestUsers( completion: { // API call
self.bestUsers.enumerated().forEach { (index, user) in // Loop
DispatchQueue.main.async {
let footer = self.debateList.dequeueReusableCell(withIdentifier: "bestUsersBox") as! UserBox
self.tableView.tableFooterView = footer
footer.setNeedsLayout()
footer.layoutIfNeeded()
footer.frame.size = footer.systemLayoutSizeFitting(UIView.layoutFittingCompressedSize)
footer.userBoxView.user = user
footerView.addSubview(footer)
footer.topAnchor.constraint(equalTo: footerView.topAnchor, constant: 0).isActive = true
footer.bottomAnchor.constraint(equalTo: footerView.bottomAnchor, constant: 0).isActive = true
footer.leftAnchor.constraint(equalTo: footerView.leftAnchor, constant: 0).isActive = true
footer.rightAnchor.constraint(equalTo: footerView.rightAnchor, constant: 0).isActive = true
}
}
})
footerView.translatesAutoresizingMaskIntoConstraints = false
return footerView
}

So, I figured out how to achieve what I wanted. Sorry if this wasn't clear.
I just used two different sections to add my content with different sources :
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let loadCell = debateList.dequeueReusableCell(withIdentifier: "loadMore", for: indexPath) as! LoadMore
if indexPath.section == 0 {
let debateCell = debateList.dequeueReusableCell(withIdentifier: "debateBox", for: indexPath) as! DebateBox
if trendingDebates.count > 0 {
if (indexPath.row == trendingDebates.count) {
loadCell.buttonTapCallback = {
self.loadMoreDebates()
}
if trendingDebates.count < totalItems {
return loadCell
} else {
return UITableViewCell()
}
} else {
let currentDebate = trendingDebates[indexPath.row]
debateCell.debateBoxView.debate = currentDebate
return debateCell
}
}
} else {
let userCell = debateList.dequeueReusableCell(withIdentifier: "bestUsersBox", for: indexPath) as! UserBox
userCell.userBoxView.user = bestUsers[indexPath.row]
return userCell
}
return UITableViewCell()
}
