This is after tapping the “DONE” button (to add a new recipe).

What I am missing?

Something stinks and I don’t know what it is. Everything was working fine before this chapter. :-(

Should I initialise “@property(nonatomic, strong) NSMutableArray *recipes;” (in PRPRecipesDocument.m)? If yes, where I should initialise it?

Ok, if I put:

_recipes = [[NSMutableArray alloc] init];

… in initWithFileURL() of PRPRecipes document, it works.

Now the question is: is this the right way to solve the problem?

I just ran into this same problem. When I compared my code vs. code provided by the authors, I noticed they added a method to override the getter for recipes in PRPRecipeDocument.m

- (NSMutableArray *)recipes {
    if (!_recipes) {
        self.recipes = [NSMutableArray array];
    return _recipes;

Ok I got the same problem.

Daniel solution worked well. I guess some update on the book would be good.

Thank you. The app works.

This post also helped me when xcode’s autocomplete wrote NSDocumentationDirectory rather than NSDocumentDirectory.

Thanks for the tip Daniel, that did the trick for me.

Fernando: Usually I do the creation of objects to back the property in the inits, but the book was showing us a different way called lazy create (pg. 98). That is why I missed it.
