Trying to solve conflicting names of functions and properties in Swift. How do I call the function position() from within a class that has a property with the same name?
import SpriteKit
func position(number: Int)->Int {
return number
}
class node: SKNode {
// Note: SKNode has a property called position (a CGPoint)

Behold the Quantum-Array: Arrays in Swift seem to be behaving like a struct and object, depending on the operation performed on the array. Open this gist in a playground. See https://twitter.com/ronaldmannak/status/474706423310340096 Update 6/6/2014: made example easier to read, removed irrelevant code, and added response from an Apple engineer.…
let anArray = [1, 2, 3] // A constant array
let anotherArray = anArray // make anotherArray point to anArray
anArray === anotherArray // true. anArray points to anotherArray
// Let's try the same with a variable array
var aMutableArray = [4, 5, 6]
var anotherMutableArray = aMutableArray // Should work like constant arrays, but...
anotherMutableArray === aMutableArray // Surprise: this returns false
// Update: According to an Apple engineer, this is a compiler bug.
