compiler error

Double checked my answer and run it in Xcode. It works, but your complier show errors.

NSNumber *foxtrot; NSNumber *planck; foxtrot = [[NSNumber alloc] initWithInt:24]; planck = [[NSNumber alloc] initWithFloat:6.626]; NSLog(@"foxtrot %@", foxtrot); NSLog(@"planck %@", planck);

While your code is technically correct, the challenge asks you to use literals: ** Declare a variable of type NSNumber named foxtrot. Initialize it with a NSNumber literal of value 24 **

NSNumber *foxtrot = @24; 
 NSLog(@"foxtrot %@", foxtrot); 
 NSNumber *planck = @6.626; 
 NSLog(@"planck %@", planck);
