"Fetching JSON Data" code challenge - Deprecated method

Hey Treehouse students!

Just wanted to let you know that the method NSData.dataWithContentsOfURL is deprecated in the latest version of Swift. The method was discontinued and will no longer be a part of the iOS libraries.

Instead, you can use the NSURL instance that we have stored in the variable courseURL in conjunction with the new constructor NSData(contentsOfURL:).

For now, the old way of doing things (using NSData.dataWithContentsOfURL) will work on Treehouse, but not on the more recent versions of Xcode. I'm sure Treehouse will update this challenge soon to reflect the new syntax!

Feel free to ping me if any of this seems unclear.

Alejandro Machado,

As per the iOS 8 documentation, the method is still available. Would you mind indicating where the documentation says it's deprecated?

Hi Prasan!

Sorry if I used the wrong term. I tried to use the method on the latest version of Xcode, and the autocompletion engine wouldn't recognize it. I'm not 100% sure this method compiles on the latest version of Xcode, since using the new constructor makes more sense than using the class method.

Sorry if this was confusing!
