swift - My Action Extension for iOS Not Showing Public.URL in the Debugger -

hi viewer have problem action extension ios i'm trying public url safari has opened can't tell if have public url since not showing in debugger. matter of fact debugger black , information shows if action extension gets interrupted/ crashes.

heres code gets public.url safari.

//get itemprovider wraps url need     var item : nsextensionitem = self.extensioncontext!.inputitems[0] as! nsextensionitem     var itemprovider : nsitemprovider = extensionitem.attachments?.first as! nsitemprovider      //pull url out     if (itemprovider.hasitemconformingtotypeidentifier("public.url")) {         itemprovider.loaditemfortypeidentifier("public.url", options: nil, completionhandler: { (urlitem, error) in             let url : nsurl = urlitem as! nsurl             //do need now, such send request server url             println(url.absolutestring!);         })     } 

is there better way of doing written in swift , plus i've around , couldn't find better solution i'm asking there tutorial or example can follow.

i believe following work:

    let item : nsextensionitem = self.extensioncontext!.inputitems[0] as! nsextensionitem     let itemprovider : nsitemprovider = item.attachments?.first as! nsitemprovider      //pull url out     if (itemprovider.hasitemconformingtotypeidentifier("public.url")) {         itemprovider.loaditemfortypeidentifier("public.url", options: nil, completionhandler: { (urlitem, error) in             let url : nsurl = urlitem as! nsurl             //do need now, such send request server url             print(url.absolutestring);         })     }
