watchkit - WKPickerItem in Objective C throwing errors -


i've got issue wkpickeritem in objective c that's driving me nuts. according examples i've seen following code should work...

interfacecontroller.h

#import <watchkit/watchkit.h> #import <foundation/foundation.h>  @interface interfacecontroller : wkinterfacecontroller  @end

interfacecontroller.m

#import "interfacecontroller.h"  @interface interfacecontroller () @property (unsafe_unretained, nonatomic) iboutlet wkinterfacepicker *picker;  @end  @implementation interfacecontroller  - (void)awakewithcontext:(id)context {     [super awakewithcontext:context];      // configure interface objects here.     nsmutablearray *arritems = [[nsmutablearray alloc] init];      (int z = 0; z <= 100; z++) {         wkpickeritem *item = [wkpickeritem alloc]; // line 1         item.title = [nsstring stringwithformat:@"%d",z]; // line 2         [arritems addobject:item]; // line 3     }      [self.picker setitems:arritems]; // line 4 }

...but i'm getting these build errors:

line 1:

use of undeclared identifier 'wkpickeritem' use of undeclared identifier 'item'

line 2

use of undeclared identifier 'item'

line 3

use of undeclared identifier 'item'

line 4
