I wish to thank the following people whose work I used while writing this book.
Cyril’s masterfully broken code examples demonstrated some nice highlights of the Clang Static Analyzer. You can find them at http://xcodebook.com/cgodefroy.
Colin’s Xcode shortcut cheat sheet saved me loads of tedium when creating Appendix B. You can find the original, downloadable version that Colin maintains at http://xcodebook.com/cwheeler.
