UITableView not showing all sections - ios

Question

I have a problem that I want to show a tableview, but separated in sections by the "status" of each item. I know how to do it with a simple string array, but I can't get to make this work with a class (Aluno) array, here's my code so far:
import UIKit
class DeliveriesTVC: UITableViewController {
let sections = ["Delivered", "Not Delivered"]
var studentList: [Array<Student>] = [[], []]
override func viewDidLoad() {
super.viewDidLoad()
for i in 0...5{
studentList[0].append(Student(alunoNome: "Aluno \(i)", alunoImg: "dani_test", alunoStatus: "Delivered"))
}
for i in 6...10{
studentList[1].append(Student(alunoNome: "Aluno \(i)", alunoImg: "dani_test", alunoStatus: "Not Delivered"))
}
self.title = "Deliveries"
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if let cellEntrega = tableView.dequeueReusableCell(withIdentifier: "EntregaCell", for: indexPath) as? EntregaCell {
let entregaCell = studentList[indexPath.section][indexPath.row]
// here i call a function in my TableViewCell class that update the cell itself
cellEntrega.updateAlunoUI(Aluno: entregaCell)
return cellEntrega
} else {
return UITableViewCell()
}
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return listaAlunos[section].count
}
func tableView(tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
return self.sections[section]
}
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 2
}
}
In the output, i just get the "first section" showing, and without a name, even with me setting the name of each section and the number of sections. I've looked everywhere but i couldn't find a solution.

Answer 1

Your numberOfSections and titleForHeader methods are wrong, it should be
override func numberOfSections(in tableView: UITableView) -> Int {
return 2
}
override func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
return self.sections[section]
}
Additionally, you should return self.sections.count instead of return 2 in numberOfSections being hardcoded as in case you add another object to the array, you will have to change the 2 to whatever elements the array has now.

Answer 2

For your numberOfSectionInTableView function, shouldn't it be override func numberOfSectionsInTableView(in tableView: UITableView) -> Int {
return 2
} with a in in front of the tableView: UITableView?
I don't see where you connect your UITableView's delegate and datasource.
Here is a tutorial to show your about using UITableView.
Take a look at "Basic Table View" - "Step 3: Set the datasource and delegate"
