The current quarter of CS193p (Spring 2015-16) is once again available on iTunesU.
The website you are looking at (http://cs193p.stanford.edu) was retired a couple of years ago, but evidently iTunesU folks still need it for demo code downloads, so that code (not including the Calculator demos) will be posted here (hopefully in a somewhat timely manner, but apologies in advance if we are slow).
This course is based on iOS 9 and Swift 2.2. If you are here looking for demo code and Swift 3.0 has come out, likely there will be incompatibilities that you'll have to resolve.
Please do not repost from this website on other websites--these downloads are for the individual use of those of you watching the course on iTunesU. Enjoy!
Here is the code from today's section.
Note that the face detection only works for one (landscape) orientation of the device.
Here is the modified Psychologist code example that I used to illustrate finding leaks and using the static analysis tool in Xcode.
Here are the slides from the section on 4/8.
Also attached is the XCode Project for the debugging example we covered. There are several bugs in this code so it does not work (that is intentional) ... see if you can find the bugs yourself. If not, the readme.txt contains a list of bugs.
