How to create a fixed-size array of objects

Question

In Swift, I am trying to create an array of 64 SKSpriteNode. I want first to initialize it empty, then I would put Sprites in the first 16 cells, and the last 16 cells (simulating an chess game).

From what I understood in the doc, I would have expect something like:

var sprites = SKSpriteNode()[64];

or

var sprites4 : SKSpriteNode[64];

But it doesn't work. In the second case, I get an error saying: "Fixed-length arrays are not yet supported". Can that be real? To me that sounds like a basic feature. I need to access the element directly by their index.

This question has already been answered, but for some extra information at the time of Swift 4:

In case of performance, you should reserve memory for the array, in case of dynamically creating it, such as adding elements with Array.append().

var array = [SKSpriteNode]()
array.reserveCapacity(64)

for _ in 0..<64 {
    array.append(SKSpriteNode())
}

If you know the minimum amount of elements you'll add to it, but not the maximum amount, you should rather use array.reserveCapacity(minimumCapacity: 64).
