Core Data specifically? No. There are many options for what you want to do. There are plists, sqlite databases (google around for objective-c or swift wrappers), and even other full fledged databases like Realm. Storing data in the cloud and retrieving it over the web is also an option. If you tell us what you're looking to do we may be better able to assist you.

Thanks for replying! For my app, one of the things I want to be able to do is remember Usernames and Passwords for my app that are created through text fields. I know the tutorial on building a Diary App in objective C covers this, but I can't seem to get the app to work, so I was looking for other methods besides Core Data.

What do you think the best method out of your list would be to use in my case, and are there tutorials you can find on using that method?

I wouldn't use plists for that. It could get very complicated if you have a number of users on a single device. I also am not sure how secure plists are for storing sensitive data. I'm thinking not very. I personally would look into sqlite. That's a half guess though based on the limited info we have on how your app works. If you want to get more detailed but don't want to put all the info out in public (which is understandable) you can drop me a line at patrickcl75 (at) gmail (dot) com and I'll see if I can't give you a more specific answer. Obviously, swap out the at and dot for the actual characters.
