Instructions: Declare another variable named 'planck' of type NSNumber and assign it the value 6.626.
My Code:
NSNumber *foxtrot;
foxtrot = [ [NSNumber alloc] initWithInt: 24];
NSLog (@"foxtrot %@", foxtrot);
NSNumber *planck;
planck = [ [NSNumber alloc] initWithInt: 6.626];

6.626 is not an int, its a float

16,009 PointsOh, so should I write initWithFloat?
Stone Preston
42,016 Pointsyeah try that. you could also use an NSNumber literal as well.
NSNumber myNumber = @1.5;

Instructions:
Declare a third NSString variable named 'favorite' and assign a concatenated string to it by appending the variable named 'color' to the variable named 'preference'. (Remember to use the method 'stringByAppendingString').
My Code:
NSString *color = @"Purple";
NSString *preference = @"My favorite color is ";
NSString *favorite = [[preference stringByAppendingString : color]];

you have too many brackets around the method call. Try
NSString *favorite = [preference stringByAppendingString:color];
