swift - Iterating over an NSOrderedSet -

-

I am trying to repeat on an example of NSOrderedSet something like this: 

  func myFunc () {var ordered ordered = NSOrderedSet (array: [42, 43, 44])

... However, this compiler error is generated for the loop line: 

  is not a member of 'NSOrderedSet' 'Generator'

Now I can convert it to an array: 

  respectively set.array {NSLog ("% i", n)}

. But i hope Wonder what was a better solution?

I am also curious to understand why it is not possible to repeat on a set, but there is no order set? NSOrderedSet implies NSFastEnumeration , so should it work right?

You ordered 

  order = NSOrderedSet ( Array: [42, 43, 44]) ordered. Set.enumerateObjectsUsingBlock {(elem, idx, stop) -> Update:

Update: as the SWIFT 1.2 (Xcode 6.3), the > NSOrderedSet correspond to type sequence and to ... in ... : 

  respectively = NSOrderedSet Array: [42, 43, 44]) for command elem {println (elem)}

javascript - data.match(var) not working it seems -

OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all. So I think the Regex is wrong but I'm not sure how. (There is a variable in PriceWinking , this is a snippet from the code.) On the website, I'm trying to remove it. & lt; Span class = "robux" data-plus = "item-privatesale-price" & gt; 115 & lt; / Span & gt; Keep in mind
