Core data object not appending to array

Question

I am having a small issue with appending my Core Data object to an array. Everything is being saved correctly in Core Data, but when I checked the array, it was empty. The code looks as follows:

func saveQA(question: String, answer: String) {
    let appDelegate = UIApplication.sharedApplication().delegate as! AppDelegate
    let managedContext = appDelegate.managedObjectContext

    let entity = NSEntityDescription.entityForName("Card", inManagedObjectContext: managedContext)
    let newQA = Card(entity: entity!, insertIntoManagedObjectContext: managedContext)
    newQA.question = question
    newQA.answer = answer

    do {
        try managedContext.save()
        playerCards.append(newQA)

    }
    catch {
        print("error")
    }
}

What seemed to work for me was changing my array from type Card, to type String. Then appending both newQA.question and newQA.answer separately to playerCards. Although I am unsure this is a valid solution. As I am unsure the question and answer will stay linked to each other that way. Any help is great, thank you in advance.

can you check the data base ( download app bundle and check your table) ? — MoLowKey

Thank you for the reply, I did do that, i checked my sqlite file to make sure everything was saved correctly which it was. It is just not appending to the array. — ACerts

I am not sure if i am misunderstaning. That is what my issue is. playerCards is my array which is staying empty after i pass in arguments for question and answer. Everything is being saved correctly to core data, but not being appended to the array. — ACerts

if your array is nil and you didn't alloc and init , it so you cant't append data to it ! — MoLowKey

playerCards.addObject(newQA)
