What is wrong with this challenge code?

NSNumber *foxtrot; foxtrot = [[NSNumber alloc] initwithint:24];

I am asked to declare a variable of type NSNumber named foxtrot. Initialize it with a NSNumber literal of value 24.

And I get the following feedback: Bummer! Make sure you created a NSNumber with the correct variable name, and check your syntax!

The word int in the method initWithInt is spelled with an uppercase i (you spelled it with a lowercase).

NSNumber *foxtrot;
foxtrot = [[NSNumber alloc] initWithInt:24];
