iOS - Array not being filled - NSDictionary / NSArray

I am having issues with XCode and require help pretty quickly... I have a plist file which I need to access and it should be filling the array of all vehicles available... Unfortunately it is not doing this. rootPath has a value. path has a value. settings does NOT have a value, it comes back as nil. Why is this? As far as I am aware this used to work on older versions of iOS / OS / XCode versions. Any ideas would be perfect! Here is the code that is going wrong with the plist file:

    -(NSArray *)AllAvailableVehicles {
    // load in vehicles from plist data

    //NSString *path = [[NSBundle mainBundle] pathForResource:
    //                  @"vehicles" ofType:@"plist"];

    NSString *rootPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
                                                              NSUserDomainMask, YES) objectAtIndex:0];

    NSString *path = [rootPath stringByAppendingPathComponent:@"vehicles.plist"];

    NSDictionary *settings = [NSDictionary dictionaryWithContentsOfFile:path];

    NSArray *array = [settings objectForKey:@"Vehicles"];

    NSMutableArray *vehicleMutArray = [NSMutableArray arrayWithCapacity:20];
    for (NSDictionary *dict in array){
        Vehicle *vehicle = [[Vehicle alloc] init];
        vehicle.displayName = [dict objectForKey:@"Display Name"];
        vehicle.keyName = [dict objectForKey:@"Key Name"];
        vehicle.maxPassengers = [[dict objectForKey:@"Max Passengers"] intValue];
        vehicle.cabCode = [dict objectForKey:@"Cabmaster Code"];
        vehicle.luggageImage = [dict objectForKey:@"Image"];
        [vehicleMutArray addObject:vehicle];
        [vehicle release];
    }
    NSArray *vehiclesArray = [[vehicleMutArray copy] autorelease];
    return vehiclesArray;

}

Solution

I have fixed the issue! It turns out I had some build rules which meant that the Plist Files would not copy over, I removed all of the build rules and it works!
