}

I assume you are declaring a Nested class and use a array declared in ViewController into a class arrays. (I tried reproducing your error by adding your snippet into a ViewController, and luckily got the same error as you mentioned :-) )

Yes it is possible. see the following code.

var array = [1, 1]

class arrays {
    var array2 = ViewController().array
}

EDIT: It is because, In Swift, an instance of an inner class is independent of any instance of the outer class. So you need to create an explicit reference to access the property of outer class.

Hope this helps.
