Two tableviews in one view controller, one table view not showing up - ios

Question

I have two TableViews in one ViewController and only one table is able to populate. I have created outlets for both tables in my view controller. Here is my viewDidLoad
override func viewDidLoad() {
super.viewDidLoad()
pickerTableView.delegate = self
pickerTableView.dataSource = self
tableView.delegate = self
tableView.dataSource = self
tableView.tableFooterView = UIView()
pickerTableView.reloadData()
tableView.reloadData()
}
It seems that the only table that is read is self.tableView and the pickerTableView is never read in the protocols for UITableView
extension MealViewController: UITableViewDelegate, UITableViewDataSource {
func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
if tableView == self.tableView {
let nameHeaderView = NameHeaderView(frame: CGRect(x: 0, y: 0, width: tableView.frame.size.width, height: 40))
nameHeaderView.delegate = self
nameHeaderView.sectionIndex = section
nameHeaderView.nameButton.setTitle(Data.userModels[section].name, for: .normal)
return nameHeaderView
} else {
return nil
}
}
func numberOfSections(in tableView: UITableView) -> Int {
if tableView == self.tableView {
return Data.userModels.count
} else {
return 0
}
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if tableView == self.tableView {
if Data.userModels[section].isExpandable {
return Data.userModels[section].itemModels.count
} else {
return 0
}
} else if tableView == pickerTableView {
return Data.userModels.count
}
else {
return 0
}
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if tableView == self.tableView {
let cell = tableView.dequeueReusableCell(withIdentifier: "nameCells", for: indexPath) as! MealTableViewCell
cell.setup(itemModel: Data.userModels[indexPath.section].itemModels[indexPath.row])
return cell
} else if tableView == pickerTableView {
let cell2 = tableView.dequeueReusableCell(withIdentifier: "pickerCells", for: indexPath) as! NamePickerTableViewCell
cell2.setup(userModel: Data.userModels[indexPath.row])
print(Data.userModels)
return cell2
}
else {
return UITableViewCell()
}
}
}
I have also applied constraints on each tableView so they both appear on the screen. When I run the app, the data for self.tableView is shown however the pickerTableView appears empty. self.tableView requires sections and pickerTableView does not require sections, could this be an issue? Also there is data in the Data.userModels array.
And just for reference, here is my UITableViewCell class:
class NamePickerTableViewCell: UITableViewCell {
#IBOutlet weak var namePickerLabel: UILabel!
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
func setup(userModel: UserModel) {
namePickerLabel.text = userModel.name
}
}
Thanks for the help!

If you do not need any section in pickerTableView, then also it has to have at least one section.
So return 1 in method numberOfSections when tableview == self. pickerTableView.
func numberOfSections(in tableView: UITableView) -> Int {
if tableView == self.tableView {
return Data.userModels.count
} else {
return 1
}
}
