swift - Iterating over an NSOrderedSet -

i'm trying iterate on instance of nsorderedset. this:

func myfunc() { var orderedset = nsorderedset(array: [ 42, 43, 44]) n in orderedset { nslog("%i", n) } }

...however loop line produces compiler error:

'nsorderedset' not have fellow member named 'generator'

now convert array this:

n in orderedset.array { nslog("%i", n) }

...but wondered if there improve solution?

i'm keen understand why it's possible iterate on set not ordered set? nsorderedset implements nsfastenumeration, should work right?

you can iterate on ordered set with

let orderedset = nsorderedset(array: [ 42, 43, 44]) orderedset.enumerateobjectsusingblock { (elem, idx, stop) -> void in println("\(idx): \(elem)") }

update: of swift 1.2 (xcode 6.3), nsorderedset conforms sequencetype , can enumerated for ... in ...:

let orderedset = nsorderedset(array: [ 42, 43, 44]) elem in orderedset { println(elem) }

swift nsorderedset
