very simple approach is to put a print in deinitialiser

deinit {

ensure that you are seeing this line getting printed on the console. put deinit in all your viewcontrollers. in case if you were not able to see for particular viewcontroller, means that their is a reference cycle.possible causes are delegate being strong, closures capturing the self,timers not invaidated,etc.
