A handy list of possible NSErrors

I stumbled upon error code -1001 recently so I went to the Apple documentation and found out that meant Connection Timeout. Here are all the different error codes one can see (copied from NSError docs):

NSError codes in the Cocoa error domain.

enum {
   NSFileNoSuchFileError = 4,
   NSFileLockingError = 255,
