Having trouble getting my location to update - ios

Question

A ViewController starts a LocationTracking. I want to NSLog the location updates (when the simulator is on freeway drive), but didUpdateLocations only logs when I uncomment the NSTimer, I can't figure out why. I feel real dumb asking this, it's probably something simple, I'm new to this and have spent a long time trying to work it out.
ViewController:
#import "ViewController.h"
#interface ViewController ()
#end
#implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
if ([defaults boolForKey:#"locationUpdate"]) {
LocationTracking *locationTracker = [[LocationTracking alloc] init];
[locationTracker startTracking];
NSLog(#"location tracking did");
//NSTimer *timer = [NSTimer scheduledTimerWithTimeInterval:10 target:locationTracker selector:#selector(logLast) userInfo:nil repeats:YES];
}
}
LocationTracking.h:
#import <UIKit/UIKit.h>
#import <CoreLocation/CoreLocation.h>
#interface LocationTracking : NSObject <CLLocationManagerDelegate>
#property (nonatomic, strong) NSMutableArray *locations;
-(void) startTracking;
-(void) logLast;
#end
LocationTracking.m:
#import "LocationTracking.h"
#interface LocationTracking()
#property (nonatomic, strong) CLLocationManager *locationManager;
#end
#implementation LocationTracking
-(void)startTracking
{
self.locations = [[NSMutableArray alloc] init];
self.locationManager = [[CLLocationManager alloc] init];
self.locationManager.desiredAccuracy = kCLLocationAccuracyBest;
self.locationManager.distanceFilter = kCLDistanceFilterNone;
[self.locationManager setDelegate:self];
[self.locationManager startUpdatingLocation];
}
-(void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations
{
NSLog(#"did update %#",[locations lastObject]);
}
-(void)logLast
{
}

The following code works fine for me:
#import "ViewController.h"
#import CoreLocation;
#interface ViewController () <CLLocationManagerDelegate>
#property (strong,nonatomic) CLLocationManager *locationManager;
#end
#implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
self.locationManager = [[CLLocationManager alloc] init];
self.locationManager.desiredAccuracy = kCLLocationAccuracyBest;
self.locationManager.distanceFilter = kCLDistanceFilterNone;
[self.locationManager setDelegate:self];
[self.locationManager startUpdatingLocation];
}
- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations {
CLLocation *loc = [locations lastObject];
NSString *lat = [NSString stringWithFormat:#"%.2f",loc.coordinate.latitude];
NSString *lon = [NSString stringWithFormat:#"%.2f",loc.coordinate.longitude];
NSLog(#"location is: %#, %#",lat,lon);
}
#end
And if you are using the simulator in Xcode, don't forget to set the location for the simulator. It defaults to "None" for new projects.
