I need to call an Objective C method from Swift -

i have interface in objective c trying call swift , not seem fall completion code. not sure missing!

@interface wplogin : nsobject  /*!  * @brief logs application returning success or failure error     object.  * if login successful credential automatically stored  *  * @param serverurlstring   address login  * @param username  username login  * @param password  password user  * @param completion completion block called after attempting login  */ - (void)logintourl:(nsstring *)serverurlstring       withusername:(nsstring *)username               password:(nsstring *)password         completion:(void (^)(wploginstatus success, nserror * error))completion;  @end 

the calling function swift looks this...

    var uid = "test"     var pwd = "test"     var url = "http://www.google.com"     var loginauth = wplogin();          loginauth.logintourl(url, withusername: uid, password: pwd, completion: { (status:wploginstatus, error:nserror!) -> void in             println("inside login")     }) 

bridging file

#import <foundation/foundation.h> #import <uikit/uikit.h> #import "wplogin.h" 

version works in objective c

if (!self.login) {     self.login = [wplogin new]; }  [self.login logintourl:url                        withusername:uid                            password:pwd                          completion:^(wploginstatus status, nserror *error) {                                 nslog(@"complete");                           }]; 

the problem in swift version wplogin object local variable (var loginauth). therefore dies before has chance do anything. make property, in objective-c version (self.login):

class myclass {     var login : wplogin = wplogin()     func mymethod () {         var uid = "test"         var pwd = "test"         var url = "http://www.google.com"         self.login.logintourl(url, withusername: uid, password: pwd, completion: {              (status:wploginstatus, error:nserror!) -> void in             println("inside login")         })     } } 

this object needs take action over time - going out on internet, logging in, calling completion handler - , cannot if dies instantly, in swift code. must persist on significant time.
