Not sure why same code works in Xcode but doesn't work in challenges?

I am new to iOS. Can you please tell me what is wrong with the code below?

UIImage *image = [UIImage imageNamed:@"background"]; UIImageView *imageview = [[UIImageView alloc]initWithImage:image]; [self.view insertSubview:imageview atIndex:0];

This was my response to the challenge question.

Hi Jacob.

It is important to note that simply initializing an image view with an image (via the initWithImage constructor) will set that image view's background to the specified image. This means that you have to do two things for this code challenge:

  1. Declare a UIImage object using the imageNamed constructor
UIImage *image = [UIImage imageNamed:@"background"];

2.Pass the UIImageView the newly declared UIImage using the initWithImage constructor 

UIImageView *imageView = [[UIImageView alloc] initWithImage:image];

All together this gives you: 

UIImage *image = [UIImage imageNamed:@"background"];
UIImageView *imageView = [[UIImageView alloc] initWithImage:image];
