ios - rotation change not triggered anymore -

i have app viewcontroller. have overwriting following methods:

override func didrotatefrominterfaceorientation(frominterfaceorientation: uiinterfaceorientation) {  override func willrotatetointerfaceorientation(         tointerfaceorientation: uiinterfaceorientation,         duration: nstimeinterval) {  override func willanimaterotationtointerfaceorientation(tointerfaceorientation: uiinterfaceorientation, duration: nstimeinterval) {  override func viewwilltransitiontosize(size: cgsize, withtransitioncoordinator coordinator: uiviewcontrollertransitioncoordinator) { 

override func shouldautorotate() -> bool not implemented.

i rotating device portrait landscape, no of methods triggered. know viewwilltransitiontosize triggered yesterday, doesn't. can't see reason.

i don't see change side regarding rotation detection.

does has hint ?
