How to declare array of custom Class object in Swift ?
4 Answers
You've declared an array but haven't initialized one.
You can do it like this:
var mNumTiles = [CCButton]()
mNumTiles.append(CCButton(title: ""))
Note that you don't have to declare the type of mNumTiles; Swift will infer it from the initialization ([CCButton]())

@iPhoneChip That's because you typed something different than what I wrote. Change
: to =.Try this:
var mNumTiles : [CCButton] = []

You have to initialize the array:
var mNumTiles = [CCButton]()
And then you can append into it.

Your variable declaration is incorrect, because the variable is not initialized (nil). To do that, you have to construct an array like this
var mNumTiles : [CCButton]! = [CCButton](count: 10, repeatedValue: nil)
Another way to do it would be to initialize an empty array and use append to add the button:
var mNumTiles : [CCButton]! = []
mNumTiles.append(CCButton....)
You should make sure to read this if you want to learn more about arrays in Swift:
