objective c - property not found on object of type error but property is there -


so i'm trying access property isportclosed(bool) in serialportcontroller , giving me error, i'm kinda new objective-c. feel should work i've got reference class *port. here link project.

error messages: ~/groundstation/groundstation/viewcontroller.m:16:22: property 'isportclosed' not found on object of type 'serialportcontroller *'

        #import <cocoa/cocoa.h>     #import "sceneview.h"     #import "serialportcontroller.h"      @interface viewcontroller : nsviewcontroller     @property (strong) iboutlet serialportcontroller *port;     @property (weak) iboutlet sceneview *accelsceneview;        @end     #import "viewcontroller.h"  @implementation viewcontroller  - (void)viewdidload {     [super viewdidload];     // additional setup after loading view.     while(!self.port.isportclosed) {      } }  - (void)setrepresentedobject:(id)representedobject {     [super setrepresentedobject:representedobject];      // update view, if loaded. }  @end

serialportcontroller.h class

#import <foundation/foundation.h> #import <orsserial/orsserial.h>  @interface serialportcontroller : nsobject <orsserialportdelegate> @property (nonatomic, strong) orsserialport *serial; @property (nonatomic, strong) orsserialportmanager *serialportmanager; @property (nonatomic) nsinteger xangle; @property (nonatomic) nsinteger yangle; @property (nonatomic) nsinteger zangle; @property (nonatomic) nsstring *stringbuffer; @property (nonatomic) bool isportclosed; @end

from downloaded project see have 2 serialportcontroller class definitions (one @ root directory, , 1 in /groundstation/), , latter doesn't have public properties. should have 1 serialportcontroller class definition linked in project (the 1 public properties).
