Swift - Updating entries in core data - swift

Question

Context:
A game, at the end of the game the user retrieves a score. A function is called to save the score to the DB
Logic:
Query the DB to check if a record exists
If a record exists, retrieve the score, if the current game score is higher then the score retrieved then update the record
If you are new user then make a new entry into DB
Issues
It keeps saving new entries to the DB and not updating the 1st entry. I only want the user to have the 1 entry that gets updated as they keep getting higher scores.
Is there anywhere I can see the localDB to see what's going on?
Also this seems verbose, is there an easier way?
Code
func saveName(score: Int, whereToStore: String) {
//1
let appDelegate =
UIApplication.sharedApplication().delegate as! AppDelegate
let managedContext = appDelegate.managedObjectContext
let fetchRequest = NSFetchRequest(entityName: "Scores")
//2
let entity = NSEntityDescription.entityForName("Scores",
inManagedObjectContext:managedContext)
let yourScore = NSManagedObject(entity: entity!,
insertIntoManagedObjectContext: managedContext)
/*Fetch results */
do
{
let fetchedResult = try managedContext.executeFetchRequest(fetchRequest) as? [NSManagedObject]
if let results = fetchedResult
{
if results.count > 1{
//Do some update code here if existing record in DB
print("Code to update number one result")
//yourScore.setValue(score, forKey: whereToStore)
let updateScore = results[0].valueForKey(whereToStore) as! Int
let updateScoreObject = results[0]
print("Score got back is \(updateScore)")
if (score > updateScore){
print("time to update")
updateScoreObject.setValue(score, forKey: whereToStore)
do {
try updateScoreObject.managedObjectContext!.save()
print("updated \(updateScoreObject)")
} catch {
let saveError = error as NSError
print(saveError)
}
}
} else {
// Do the saving here if you are a new user
//3
yourScore.setValue(score, forKey: whereToStore)
print("DOES THIS CODE RUN")
print("your score is\(yourScore)")
//4
do {
try managedContext.save()
//5
print("worked, I saved")
} catch let error as NSError {
print("Could not save \(error), \(error.userInfo)")
}
}
}
else
{
print("Could not fetch result")
}
}
catch
{
print("There is some error.")
}
}
Update
Added
let documentsUrl = NSFileManager.defaultManager().URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask).first!
print("\(documentsUrl)")
So I can find the local SQLite and opened up with a DB viewer, as expected it keeps saving new entries rather than updating the 1st
