    func willRunOnceCoach() -> () {
    //        struct TokenContainer {
    //            static var token : dispatch_once_t = 0
    //        }
    //
    //        dispatch_once(&TokenContainer.token) {
    //            print("This is printed only on the first call")
    //            self.createCochMark()
    //        }
    //    }

Above is the dispatch_once code block and i want to convert it to swift 3. How can i do that?? AS of now i m getting the following error: "dispatch_once is unavailable in swift " Any help would be appreciated
