I have a problem, my objects every time I save them are reflected in uitableview in a duplicate way, does anyone know how to solve it or if I have a problem in my code?
	 import CoreData
	 import Foundation
	class ViewController: UIViewController {
//MARK:= Outles
@IBOutlet var tableView: UITableView!
//MARK:= variables
var context = (UIApplication.shared.delegate as! AppDelegate).persistentContainer.viewContext
var items: [Entity]?
var duplicateName:String = ""
//MARK:= Overrides
override func viewDidLoad() {
		super.viewDidLoad()
		tableView.delegate = self
		tableView.dataSource = self
		
		
		fetchPeople()
		addPeople(context)
		print(" nombres: \(items?.count)")
		
}
override func viewWillAppear(_ animated: Bool) {
}
//MARK:= Core Data funcs
func fetchPeople(){
		do{
				self.items = try! context.fetch(Entity.fetchRequest())
				
				DispatchQueue.main.async {
						self.tableView.reloadData()
				}
				
		}catch let error as NSError{
				print("Tenemos este error \(error.debugDescription)")
		}
		
}
func addPeople(_ contexto: NSManagedObjectContext) {
		
		let usuario = Entity(context: contexto);
		usuario.nombre = "Valeria";
		usuario.edad = 25;
		usuario.eresHombre = false;
		usuario.origen = "Ensenada,B.C"
		usuario.dia = Date();
		do{
				try! contexto.save();
				
		}catch let error as NSError{
				print("tenemos este error en el guardado \(error.debugDescription)");
		}
		fetchPeople()
		
		
}
func deletDuplicates(_ contexto: NSManagedObjectContext){
		
		let fetchDuplicates = NSFetchRequest<NSFetchRequestResult>(entityName: "Persona")
	 //
			 //				do {
			//						items = try! (contexto.fetch(fetchDuplicates) as! [Entity])
			//				} catch let error as NSError {
	//						print("Tenemos este error en los duplicados\(error.code)")
			 //				}
		
	 let rediciendArray = items!.reduce(into: [:], { $0[$1,default:0] += 1})
		print("reduce \(rediciendArray)")
		let sorteandolos = rediciendArray.sorted(by: {$0.value > $1.value })
		print("sorted \(sorteandolos)")
		let map = sorteandolos.map({$0.key})
		
		print(" map : \(map)")
	}
} // End of class
I have tried to solve the error and I have investigated what it is for my array but the truth is that I have not had the solution no matter how much I look for it, if someone could help me it would be of great help.
