Referencing core data attribute from declared variable - ios

Question

I'm following a swift development course for beginners and am trying to make a very simple app that creates new tasks with an entered text once a button is pressed, but I am encountering a few errors that I can't seem to understand.
The errors happen in my ViewController and the editor tells me my Core Data Entity does not possess an attribute named "corename" while it very well does.
Here is a screenshot of the errors : 3 errors
And here is my code :
import UIKit
class ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
#IBOutlet weak var tableView: UITableView!
var tasks : [Taskentity] = []
override func viewDidLoad() {
super.viewDidLoad()
tableView.dataSource = self
tableView.delegate = self
// Do any additional setup after loading the view, typically from a nib.
}
override func viewWillAppear(_ animated: Bool) {
//Get the data from Core data
getData()
//Reload the table view
tableView.reloadData()
}
func numberOfSections(in tableView: UITableView) -> Int {
return tasks.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath : IndexPath) -> UITableViewCell {
let cell = UITableViewCell()
let task = tasks[indexPath.row]
if (task.isImportant == true){
cell.textLabel?.text = "😅 \(tasks.corename!)"
} else {
cell.textLabel?.text = tasks.corename!
}
return cell
}
func getData() {
let context = (UIApplication.shared.delegate as! AppDelegate).persistentContainer.viewContext
do {
tasks = try context.fetch(Taskentity.fetchRequest())
} catch {
print("Fetching Data")
}
}
}

Answer 1

Tasks is a Array of Taskentities, you probably meant to access task.corename not tasks.corename
if (task.isImportant == true){
cell.textLabel?.text = "😅 \(task.corename!)"
} else {
cell.textLabel?.text = task.corename!
}
And for the TableViewDelegate problem, just make sure to implement all necessary funcs... You are missing 1:
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 0
}
