i want index user has tapped.i have tried several ways detect none of working. here have tried.

   func carousel(carousel: icarousel, didselectitematindex index: int) {         print("this has been tapped carousel \(index)")     }      func carouselcurrentitemindexdidchange(carousel: icarousel) {         let index=carousel.currentitemindex         print("this current index \(index) ")     }      func carousel(carousel: icarousel, viewforitematindex index: int, reusingview view: uiview?) -> uiview {         let webv:wkwebview!         webv = wkwebview(frame: cgrectmake(10, 10, 250, 250))         if let updatedresource = mydict[index+1]{//name of resource want load             let url =  nsbundle.mainbundle().urlforresource(updatedresource, withextension: "html")             let requestobj = nsurlrequest(url: url!);             webv.loadrequest(requestobj);             let tapgesture = uitapgesturerecognizer(target: self , action: selector("tapdetected"))             //tapgesture.numberoftapsrequired = 2             tapgesture.enabled = true             webv.userinteractionenabled = true             webv.addgesturerecognizer(tapgesture)             // setuserinteractionenabled = true             print("this has been rendered \(index)")           }         return webv      }      func tapdetected(sender:uiswipegesturerecognizer) {         print("yes tap has been detected :)") 

might not since i'm using objective-c tap getting detected in

- (void)didtap:(uitapgesturerecognizer *)tapgesture  

method.

 [_delegate carousel:self didselectitematindex:index];  nslog(@"selected app @ index: %d", index); 

works expected. i'm using icarousel version 1.8.2
