How to add to an array of objects, an object that is inherited? (Swift, XCode)

Question

var allCards = [CCard]
var cardsMade = 0

^^ is outside of my view controller class as to make it global and accessible in all other view controller files.

in another view controller i have

@IBAction func saveInfo(sender: UIButton) {
    let a = CCreature(n: cName!, e: cExpansion, ec: cEnergy!, tc: cTurnCount!,
        ef: cEffect!, at: cStrength!, ht:cHealth!, sp: cSpeed!, sb: false)
    allCards.append(a)
    cardsMade++}

so when the saveInfo button is pressed, i put all the information the user has typed (which were in UITextFields, and then saved into the corresponding vairables cEnergy etc..) into a subclass of CCard called CCreature, with all of the information. After I create the instance of the class, i am trying to store in the array allCards. I am getting an error on the line:

var allCards = [CCard]

Expected member name or constructor call after type name

And in the line where a is appended to the array i am getting this error:

Cannot convert value of type 'CCreature' to expected argument type 'inout Array < CCard >'

I was also getting this error message before, when my program was compiling:

fatal error: Array index out of range

Any ideas?

As you have it [CCard] is a type declaration, you could use it as:

var allCards : [CCard]

but, that won't actually initialize allCards to be useful, alternatively, you could actually create the array and initialize it using:

var allCards = [CCard]()

Where you're using the default array constructor

It's not the entirety of your example, because you didn't include a lot of the pieces, but stripped down to show usage, would be:

var allCards = [CCard]()

func saveInfo() {
    let a = CCreature()
    allCards.append(a)
}
