  • Hi,

    Liking the tutorial but im stuck using xcode 4.2 - followed everything but had to import the appdelegate.h file in the implementation file to work, but when the app runs, i get sigkil and get directed to the main.m file....

    Any ideas??

  • @boxed2003 Since you are calling the appDelegate in the view controller you would have to import it. SIGKILL usually is due to an invalid variable. Please download the code and see what you are doing differently

  • Great video...

    I updated to Lion and Xcode 4. Things are quite different in it and I cannot get the app which ran in Xcode 3 to run in 4. Now that I'm on Lion, I cannot go back to Xcode 3 either.

    Will you be publishing a tutorial on Core Data with Xcode 4?

  • @ericriutort Actually, there's not a whole lot of difference in creating a core data app in Xcode4. I just tried running the app in Xcode 4 with Lion and it ran without any problems. Are you having any specific issue?

  • what if I want to do this for a application that already exist. Can I add "Use Core Data" after creation?

  • @Wakka12321 Sure you can. You would just have to add all the code manually that is generated by Xcode when you use the application template. Which would mean adding all the methods in the AppDelegate and creating the Data Model. It's a bit of work but in the long run you will be glad you made the changes.

  • good work, but how can we vieuw our database now and display all the recipes?

    can you explain that please

  • this is the by far the best and simplest explanation for Core Data i ever seen. its even better than the apple documents and tutorial videos.

    but i hope for more using Xcode 4.3 please.

  • Excellent job. You should make more of these!

  • this is great! Thank you.

  • @MacarioPrudencia Hey, I think it shows that way because that file doesn't have an extension. It's hosted on Github so you can see the contents of the file
