Segmented control and table view issue swift - swift

Question

so I am creating a table view with segmented control. at first - I didn't do segmented control but modified some code to at it. When I add numbers to my array, it is not actually populating the cells of the table view. In the table view every time I click a button that appends an amount to the array, the lines increase, but no data is shown. So I know it is working, but it is just not actually displaying the numbers in the table view cells. is there a specific reason why my code will not populate the views?
class SpendingHistoryViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
var savedInformation = false
var newDefault : Double?
var selectedSegment = 1
let array2 = ["1","2","3"]
let userDefaults = UserDefaults.standard
#IBOutlet weak var tableViewSpending: UITableView!
#IBOutlet weak var youSpentLabel: UILabel!
#IBOutlet weak var youSavedLabel: UILabel!
#IBOutlet weak var segmentControl: UISegmentedControl!
override func viewDidLoad() {
super.viewDidLoad()
self.tableViewSpending.delegate = self
self.tableViewSpending.dataSource = self
//GETS user defaults that was set in ADDSUBTRACTMONEY VC - and then sets the default to Array- then gets total
let moneySpentArray = UserDefaults.standard.array(forKey: "moneySpent") as? [Double] ?? [Double]()
AddSubtractMoneyController.moneySpentArray = moneySpentArray
let arraySum = moneySpentArray.reduce(0.0, +)
youSpentLabel.text = String(format: "%.2f", arraySum)
}
#IBAction func spentSavedAction(_ sender: UISegmentedControl) {
if sender.selectedSegmentIndex == 0 {
selectedSegment = 1
}
else {
selectedSegment = 2
}
self.tableViewSpending.reloadData()
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if selectedSegment == 1 {
return(AddSubtractMoneyController.moneySpentArray.count)
}
else {
return array2.count
}
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
//let cell = UITableViewCell(style: UITableViewCellStyle.default, reuseIdentifier: "cell")
//let cell2 = UITableViewCell(style: UITableViewCellStyle.default, reuseIdentifier: "cell2")
let cell2 = tableViewSpending.dequeueReusableCell(withIdentifier: "cell2")! as UITableViewCell
let cell = tableViewSpending.dequeueReusableCell(withIdentifier: "cell")! as UITableViewCell
cell.textLabel?.text = String(format: "%.2f", AddSubtractMoneyController.moneySpentArray[indexPath.row])
cell2.textLabel?.text = array2[indexPath.row]
self.tableViewSpending.reloadData()
if selectedSegment == 1 {
return cell
}
else {
return cell2
}
}
}
