Coredata in swift - ios

Question

Hello I am having an issue with core data in Swift, this doesn't show an error but also doesn't print anything when I believe it should be returning 'Joe' + 'pass' in console. Could anyone help please?
import UIKit
import CoreData
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
var appDel:AppDelegate = UIApplication.sharedApplication().delegate as! AppDelegate
var context:NSManagedObjectContext = appDel.managedObjectContext
var newUser = NSEntityDescription.insertNewObjectForEntityForName("Users", inManagedObjectContext: context) as NSManagedObject
newUser.setValue("Joe", forKey: "username")
newUser.setValue("pass", forKey: "password")
do {
try context.save()
} catch let error {
print("Couldn't save user data")
print(error)
}
let request = NSFetchRequest(entityName: "Users")
request.returnsObjectsAsFaults = false
do {
var results = try context.executeFetchRequest(request)
results = results as! [NSManagedObject]
if results.count > 0 {
for results in results {
print(results)
}}
} catch let error as NSError {
print(error)
}
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}

Answer 1

You should create your own coredata class (as a subclass of NSManagedObject) and then create the array out of that class.
specify exactly what you want to print. In your case
newUser.username

Answer 2

I finally realised what my issue was, I hadn't actually renamed by Entity to 'Users' I'd kept it as 'Entity' so when I was doing
let newUser = NSEntityDescription.insertNewObjectForEntityForName("Users", inManagedObjectContext: context) as NSManagedObject
let request = NSFetchRequest(entityName: "Users")
I should have actually have replaced both Users with 'Entity' which now fixes my issue, thanks I guess for your help anyway!
