Given that the code samples are short. And that they often go through a few revisions. And that if I publish the code some people will read it instead of typing it in. I’m not going to make the code available.
“But I want to check mine against yours!” If yours works, it is good enough for where you are. If it doesn’t, hunting down your own errors will be a very valuable use of your time.
“But I don’t like typing that much!” It really isn’t that much typing, and you need to do the typing so that you really learn how code comes together.
On the books where there is more code (“iOS Programming” and “Cocoa Programming”), we do publish the solutions. In this case, I’m going to help you have the discipline to do the right thing: I’m not publishing the solutions.
The forum is here. I check it pretty regularly. You will not get stymied because you don’t have access to BNR-approved solutions.
