The challenge is case-sensitive. The given enum names are all lowercase (e.g. "headline", "body", "footnote". Update the enum cases and the switch statement so that those names are lowercase and your code should pass.

Enum names are captialized. Enum members are lowercase: this is just a convention. Aananya code works in Swift and the only reason why his /her code fails is because Treehouse is enforcing the convention in its code review. Overall, if Treehouse provides you with set code (the Text enum in this case), it is not a good idea to change it unless they specifically say to do so. Otherwise you can get errors like these.
