I do not think I have ever purchased a book with such broken code samples. Is no one else having this problem? I must be doing something wrong.
Everything from the weird “Error: The recipes database is either corrupt or was created by a newer version of Grokking Recipes. Please contact support to assist with this error. (null) (null)” to the ‘CoreFoundation/CoreFoundation.h’ file not found and the The document “MyDocument.nib” could not be opened. The operation couldn’t be completed. *** -[NSKeyedUnarchiver initForReadingWithData:]: incomprehensible archive (0x62, 0x70, 0x6c, 0x69, 0x73, 0x74, 0x30, 0x30).
I don’t have a very warm and fuzzy feeling about following the advice in a book that can’t provide working samples.
Please fix your sample code and make it available for download.
