Help with CurrencyConverter in DP4

You needed to add:
#import "Converter.h"
after your first #import in ConverterController.m. That way the compiler  
can find the convertAmount: byRate: method that is declared in Converter.h.

You did alloc/init the Converter. You did it in InterfaceBuilder by  
pointing/clicking and  instantiating a Converter (which is actually done  
when the nib file is loaded). I wouldn't personally do it this way for this  
kind of object, but it is certainly valid (Converter never talks directly  
to the UI, so there really isn't any reason to have it in IB). But then  
that is probably outside the scope of the tutorial. You could certainly  
create a Converter object in your convert: method the first time convert:  
gets called and maintain a pointer to it if you wish (of course, don't  
forget to release it).

It would have been easier if you created a .tar.gz archive.
