cellForRowAt not being called but numberOfRowsInSection is - swift

Question

So, I have checked that tableview.reloadData() is being called on the main thread and that numberOfRowsInSection has values. When I look at the view hierarchy the tableView is clearly there and shows the background colour when set. What I have noticed that is odd is that the view hierarchy says its an Empty list(understandable) but it contains two UIImageView's one in the top right and one in the bottom left. Don't understand this at all. My tableView is nested in an iCarousel which I'm sure is where the issue lies. My code is entirely programmatic, so here is what i think may be of value:
iCarouselDatasource:(carousels dont have cells but views instead)
class BillCarouselDataSource: NSObject, iCarouselDataSource {
var bills = [Bill]()
func numberOfItems(in carousel: iCarousel) -> Int {
return bills.count
}
func carousel(_ carousel: iCarousel, viewForItemAt index: Int, reusing view: UIView?) -> UIView {
let bill = bills[index]
let billCarouselView = BillCarouselView(bill: bill)
billCarouselView.frame = carousel.frame
billCarouselView.setupView()
return billCarouselView
}
}
iCarousel view(cell)
class BillCarouselView: UIView {
private var bill: Bill!
private let nameLabel = CarouselLabel()
private let locationLabel = CarouselLabel()
private let dateLabel = CarouselLabel()
private let splitButton = CarouselButton()
private let tableView = UITableView()
required init(bill: Bill) {
super.init(frame: .zero)
self.bill = bill
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
}
func setupView() {
setupHierarchy()
setupViews()
setupLayout()
}
private func setupHierarchy() {
addSubview(nameLabel)
addSubview(locationLabel)
addSubview(dateLabel)
addSubview(tableView)
addSubview(splitButton)
}
private func setupViews() {
accessibilityIdentifier = AccesID.carouselView
isUserInteractionEnabled = true
layer.cornerRadius = Layout.carouselViewCornerRadius
backgroundColor = Color.carouselView
nameLabel.text = bill.name
nameLabel.textAlignment = .center
nameLabel.accessibilityIdentifier = AccesID.carouselNameLabel
locationLabel.text = bill.location
locationLabel.textAlignment = .left
locationLabel.accessibilityIdentifier = AccesID.carouselLocationLabel
dateLabel.text = bill.creationDate
dateLabel.font = Font.carouselDateText
dateLabel.textAlignment = .right
dateLabel.accessibilityIdentifier = AccesID.carouselDateLabel
let dataSource = CarouselTableViewDataSource()
let delegate = CarouselTableViewDelegate()
tableView.backgroundColor = .clear
tableView.separatorStyle = .none
tableView.dataSource = dataSource
tableView.delegate = delegate
tableView.register(CarouselTableViewCell.classForCoder(),
forCellReuseIdentifier: "carouselTableViewCell")
dataSource.items = bill.items
tableView.reloadData()
let buttonTitle = "Split £\(bill.totalPrice())"
splitButton.setTitle(buttonTitle, for: .normal)
}
private func setupLayout() {
nameLabel.pinToSuperview(edges: [.top, .left, .right])
locationLabel.pinToSuperview(edges: [.left],
constant: Layout.spacer,
priority: .required)
locationLabel.pinTop(to: nameLabel, anchor: .bottom)
locationLabel.pinRight(to: dateLabel, anchor: .left)
dateLabel.pinToSuperview(edges: [.right],
constant: -Layout.spacer,
priority: .required)
dateLabel.pinTop(to: nameLabel, anchor: .bottom)
tableView.pinTop(to: dateLabel, anchor: .bottom)
tableView.pinToSuperview(edges: [.left, .right])
tableView.pinBottom(to: splitButton, anchor: .top)
splitButton.pinToSuperview(edges: [.left, .right, .bottom])
}
}
class CarouselTableViewDataSource: NSObject, UITableViewDataSource {
var items: [Item]? {
didSet {
let duplicatedItems = items
filteredItems = duplicatedItems?.filterDuplicates { ( $0.creationID ) }
}
}
private var filteredItems: [Item]!
func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return filteredItems.count
}
//Set what each cell in the tableview contains.
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell: CarouselTableViewCell = tableView.dequeueReusableCell(withIdentifier: "carouselTableViewCell") as! CarouselTableViewCell
let duplicateItems = items?.filter { Int($0.creationID)! == indexPath.row }
let quantity = "\(duplicateItems!.count) x "
let name = duplicateItems![0].name
let price = formatPrice(duplicateItems![0].price)
cell.quantityLabel.text = quantity
cell.nameLabel.text = name
cell.priceLabel.text = price
return cell
}
private func formatPrice(_ stringPrice: String) -> String {
var formattedPrice = stringPrice
let price = NSNumber(value: Double(stringPrice)!)
let formatter = NumberFormatter()
formatter.numberStyle = .currency
if let formattedTipAmount = formatter.string(from: price) {
formattedPrice = "Tip Amount: \(formattedTipAmount)"
}
return formattedPrice
}
}
class CarouselTableViewCell: UITableViewCell {
var containerView = UIView()
var quantityLabel = UILabel()
var nameLabel = UILabel()
var priceLabel = UILabel()
override init(style: UITableViewCellStyle, reuseIdentifier: String?) {
super.init(style: style, reuseIdentifier: "carouselTableViewCell")
setupHierarchy()
setupViews()
setupLayout()
}
required init(coder aDecoder: NSCoder) {
fatalError("init(coder:)")
}
private func setupHierarchy() {
containerView.addSubview(quantityLabel)
containerView.addSubview(nameLabel)
containerView.addSubview(priceLabel)
containerView.addSubview(containerView)
contentView.addSubview(containerView)
}
private func setupViews() {
quantityLabel.textAlignment = .left
quantityLabel.backgroundColor = .clear
quantityLabel.textColor = Color.carouselText
nameLabel.textAlignment = .left
nameLabel.backgroundColor = .clear
nameLabel.textColor = Color.carouselText
priceLabel.textAlignment = .right
priceLabel.backgroundColor = .clear
priceLabel.textColor = Color.carouselText
}
private func setupLayout() {
containerView.pinToSuperview(edges: [.left, .right])
containerView.pinToSuperviewTop(withConstant: -2, priority: .required, relatedBy: .equal)
containerView.pinToSuperviewBottom(withConstant: -2, priority: .required, relatedBy: .equal)
quantityLabel.pinToSuperview(edges: [.top, .left, .bottom])
nameLabel.pinToSuperview(edges: [.top, .bottom])
nameLabel.pinLeft(to: quantityLabel, anchor: .right)
nameLabel.pinRight(to: priceLabel, anchor: .left)
priceLabel.pinToSuperview(edges: [.top, .right, .bottom])
}
}
Everything in the iCarousel view(cell) shows apart from the contents of the cell.
Any help or insight would be great
