iPhone- Error With Spritekit Game - ios

Question

I'm making a app using Apple's Spritekit framework. My app has multiple view controllers and everything works fine. However, I tried to make a scene that I would load in one of my viewcontrollers, but that did not work. I get no errors at all: it just does not work. Everything works except when I try to load my scene, everything crashes. Also, I was thinking, could my problem be that I have already added a view and put labels and buttons, etc... on that view before I load my scene? To elaborate, could the problem be that I have already added uiimages, etc... to the view using interface builder before I loaded my scene programmatically? Any help would be great. Here is my code for the view controller where I call my scene:
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
SKView * skView = (SKView *)self.view;
// Create and configure the scene.
SKScene * scene = [MyScene sceneWithSize:skView.bounds.size];
scene.scaleMode = SKSceneScaleModeAspectFill;
// Present the scene.
[skView presentScene:scene];
[super viewDidLoad];
// Do any additional setup after loading the view.
}
And here is my code for the actual scene:
-(id)initWithSize:(CGSize)size {
if (self = [super initWithSize:size]) {
/* Setup your scene here */
SKSpriteNode *mainTurrentSprite = [SKSpriteNode spriteNodeWithImageNamed:#"mainTurrent.png"];
mainTurrentSprite.position = CGPointMake(self.view.center.x, 0);
[self addChild:mainTurrentSprite];
}
return self;
}
And here is my crash/error log :
