swift - Segment controller issue -

i've got segment controller above connected code bellow.

@iboutlet weak var coatsegmentcontroller: uisegmentedcontrol!  @ibaction func coatselectinput() {          switch (self.unitsegmentcontroller.selectedsegmentindex) {          case 0:             coatsetter = 1             //println("switched coat 1")             println(unitsegmentcontroller.selectedsegmentindex)          case 1:             coatsetter = 2             //println("switched coat 2")             println(unitsegmentcontroller.selectedsegmentindex)          case 2:             coatsetter = 3             //println("switched coat 3")             println(unitsegmentcontroller.selectedsegmentindex)          default:             println("coat switch did not work")          }       } 

no matter segment select return i've selected first segment.

if hook unit segment outlet works. unit 1 stops working.

@iboutlet weak var unitsegmentcontroller: uisegmentedcontrol! 

any idea be? i've tried everything. delete , create again many times. nothing seems work.

here full code view.
