CMPedometer queryPedometerDataFromDate returns error 103

You should hold your CMPedometer variables as a property of you class, not as Local variables. And then it will work.

CMErrorDomain when calling CMPedometer methods

Following Larme's advice, I created a property in my ViewController and synthesized it, like so:

@interface MainViewController(){
@property (strong, nonatomic) StepService *stepService;
@end

@implementation MainViewController
@synthesize stepService

I was then able to create and call the method containing queryPedometerDataFromDate like so:

stepService = [[StepService alloc] init];
[stepService storeData];
