multithreading - Inter-thread communication in Swift? -

-

itemprop = "text">

My goal is to parse a large XML file (20 GB) with swift. There are some performance problems with NSXMLParser and Swift Bridging the object, so I'm looking at multi-threading. Specifically lower division:

  1. The main thread - purse data
  2. The worker submits the thread-type type in SWIFT and sends it to 1. Casting of ObjC NSDictionary [String: string] is the biggest obstacle, it is also the main reason for isolating it on multiple threads.
  3. Worker thread - Parsing XML in OBC types - and sends 2. NSXLL parse is a push-parser, once you start parsing, you can not stop it.

The data should be parsed sequentially, so the input order should be maintained. I think allow two parallel processing of non-blocking to run an NSRunLoop on both 1 and 2. According to the documentation of the apple, communication between the thread can be obtained by calling. However this symbol is not available in Swift.

I do not think GCD will fit in the form of a solution

How can one get up to (like NSRunLoops on many sources) using swift?

I used the first time last month, and for this subclass An easy easy object, you can either chain them together with the whole block or you can set the operations for each other's dependency so that they can be executed sequentially.

Passing in the object is also very easy to communicate with NSOption.

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
