Adapting Data for Display-Challenge 2/3

"Create an instance of NSData named 'data' with the previously created 'url' object."

--->Bummer! Looks like you have not defined 'data'

I don't understand what I'm doing wrong. Any suggestions?

images.m 
NSURL *url = [NSURL URLWithString:@"http://teamtreehouse.com/assets/homepage/logo.png"];
NSData *data = [NSData dataWithContentsOfURL:url];

having the same problem; just posted a question myself. the syntax looks good, and is exactly the same as the working syntax in my blog program, which i've finished. This is the only challenge i haven't finished and it's rather frustrating.

Sorry for the inconvenience, but this challenge has now been fixed. Essentially the logo URL was broken which was causing the challenge to fail. I've updated the logo URL to: 'http://treehouse-code-samples.s3.amazonaws.com/logo.png'. So make sure you use the new URL when creating an instance of NSURL.

Tried this one too, to no avail, seems something is wrong in the editor, used exactly the same code as I used in the past

I've reported this to the support team. Hopefully will be resolved soon and we can all progress.

it should pass with this line: NSData *data = [NSData dataWithContentsOfURL:url];

I'm also unable to pass this. Checked my syntax countless times, and re-written it.
