I'm creating a Core Data model for my application. I would like to be able to look inside it to see what I have stored in there.
Is there an easier way than searching for the backing store (mine should be SQLite) and reading it from there? Doesn't seem very Apple-esque.
Once your app has run in the simulator and created the persistent store file, you can find the file in your app's Documents directory.
Your app data will be folder inside (~ is your home directory):
~/Library/Developer/CoreSimulator/<device>
In versions prior to XCode 6, the path was:
~/Library/Application Support/iPhone Simulator/User/Applications/
I sort by "Date Modified" to find the app that I just built.
For viewing a SQLite file, check out Base and/or Core Data Editor.
You can also use FireFox's Add-on tool SQLite Manager (FREE). I use it and it works well.
If you are using iOS 10 & Swift get it into your AppDelegate.swift:
let container = NSPersistentContainer(name: "***")
print(container.persistentStoreDescriptions.first?.url)
Then you'll see something like that:
Optional(file:///Users/<SomeUser>/Library/Developer/CoreSimulator/Devices/956F0003-5DA4-4588-97C1-A9A83767F341/data/Containers/Data/Application/9765FDE1-6971-4706-987B-96FBD3F462BF/Library/Application%20Support/***.sqlite)
You can try a little free tool called CoreDataPro. Pretty nice. Here
Core Data Lab is a dedicated Core Data viewer that offers everything to view and analyze the Core Data database of your app, like automatic search for databases, data change tracker, simulator browser, a predicate editor, data editor, a built-in web and image content viewer, and much more.

Update to this thread, The iphone simulator location has been moved to a different location in Xcode7 and Xcode8. It is now in:
~/Library/Developer/CoreSimulator/...
where ~ is your home directory.
Any of the previous solutions will still work, but you won't be able to find the correct folder if you use the previous links.
Also try sqlite database browser. its free and reflects that fact. very useful though!

I created a macOS app to browse your Core Data content. It hides Core Data implementation as you see when you use a SQLite browser. Also you can list all your latest run apps and simulators, with this you can easily find the app you are looking for. More info here:
http://www.microedition.biz/simMagnifier
It has other features like access Simulator's folders such as Documents, Application Support, etc. You can check the content of NSUserDefaults too.
The app is not free sorry! but at least you have a 7 days trial.
Here is the full path, apparently it changed since gerry3's answer
~/Library/Application Support/iPhone Simulator/<Simulator>/Applications/<ApplicationID>/Documents/<NAME>.sqlite
So a correct path would like this:
~/Library/Application Support/iPhone Simulator/7.1-64/Applications/C1F3C2E5-987A-4DF7-91EF-955AE6E52621/Documents/TestApp.sqlite
3 Easy Steps
install liya application, its free, Size 3.1 MB, so installs in 1 minute.
Link https://itunes.apple.com/us/app/liya/id455484422?mt=12.
Open Finder, Press "Ctrl + G" OR "CMD + Ctrl + G", Paste ~/Library/Developer/
In Developer Folder, search for your Core Data model name (eg. MyProjectModel).
Open MyProjectModel.d file Or 'MyProjectModel.sqlite' using liya. In liya, select a table, Click on "Run SQL Command".
Done.

In my application's documents folder, I do not find my SQLite database
Library/Application Support/iPhone Simulator/6.1/"random app
id"/Documents/
^This folder is empty
MagicalRecord seems to be working, I just have no idea how to find the database.
I use the following to set up Magical Record
[MagicalRecord setupAutoMigratingCoreDataStack];
So where does MagicalRecord store its database?
MagicalRecord stores, by default, all data stores in the following location:
{App Folder}/Library/Application Support/{App Name from Info.plist}/{storeName.sqlite}
This is easily accessible from the simulator as well as documents.
You can log your SQlite file location using the following NSPersistentStore MR addition :
[NSPersistentStore MR_urlForStoreName:[MagicalRecord defaultStoreName]]
If you know the name of the sqlite file then just do a search in OSX for that file to find the directory. Otherwise the file was never created.
Make sure you are setting up the CoreData stack correctly as per the documents.
+ (void) setupCoreDataStackWithAutoMigratingSqliteStoreNamed:(NSString *)storeName;
Swift + Xcode 7 + simulator 9.0
Please go to your AppDelegate.swift
change
MagicalRecord.setupCoreDataStackWithStoreNamed("yourDBName.sqlite")
to
MagicalRecord.setupCoreDataStackWithAutoMigratingSqliteStoreNamed("yourDBName.sqlite")
Now you can locate the yourDBName.sqlite at
/Users/userName/Library/Developer/CoreSimulator/Devices/"random app id"/data/Containers/Data/Application/"random app id"/Library/Application Support/ProjectName

I'm new with dealing with the .sqlite3 in iphone, I created a sqlite3 file in
/Users/myLab/Library/Application Support/iPhone Simulator/5.1/Applications/308C4355-D8EE-4524-A7F9-638DEB68B298/Documents/file.sqlite3
and I inserted the tables into it using Terminal.app and everything works ok with my app.
but when I moved this application to another device, opened by xcode and trying to run it, I discovered that my tables are not found in this .sqlite3 file in another device.
how can I save my tables in .sqlite3 file??
Whereas this much info is adiquate to answer you question though i am providing some checkmarks to check for:
Do you have file.sqlite3 in your app resource folder?
Do you have that given table in that resource file.sqlite3 file?
Have you made any changes to the file.sqlite3 placed in the resource folder while app is running? if yes then try deleting that file.sqlite3 from the resource and add again to the resources.
All these checkpoints may make your app work well.
BestLuck..
Can someone help me find where CoreData is storing the SQL file it creates in iOS applications?
So far I've tried "Show package contents" on the .xcdatamodel file and also the .xcodeproj file...No dice!
Is there an editor for looking at the contents of these SQL files?
Cheers.

The url parameter of [NSPersistentStoreCoordinator addPersistentStoreWithType:configuration:url:options:error] specifies the location of the file. Find this call in your code and see where you've stored it. XCode templates will put it into the top of your application documents directory, but you can put it anywhere you like.
Note that Apple considers the contents of this database to be opaque and non-user-modifiable. Playing with the data in your store is likely to cause issues with Core Data.
It's typically saved into your application's documents directory, with the name of your data model.
So, for example, if my data model is called AppData.xcdatamodeld, it will be AppData.sqlite inside my app's document directory. You shouldn't really need to touch the .sqlite file though.
Hope that helps!
Core Data editor --> http://christian-kienle.de/CoreDataEditor/
this is a follow on from this question and the link given it seems that when an app is updated all of the files in the documents directory are copied into the updated apps documents directory and also anything in Library/Preferences. Whats the best way to simulate this for testing purposes?
Just copy the files in ApplicationSupport/iPhone Simulator etc? or has anyone developped any funky techniques for testing this.
I have created .sqlite file in my application's documents folder and created some dummy entries in my database table.
Now just change you code build new application without changing any of the certificate and profile information load the new application.
Now check for the old database table records. It will be definitely preserve under your Document directory in .sqlite file.
This is what i followed when i want to check it for same thing.
If anyone know better way then please feel free to suggest new things.
Jim.
i need to copy this database file and save it in someother location or i can take backup of the db file. is there a way to do this programmatically.
Thanks

Unless you've jailbroken your iPhone, there's no way of accessing the sqlite3 database directly on the phone.
If you're talking about getting access to the database from your computer, you can do it by grabbing the database files out of the iPhone backup files. To do that, you'll need to grab a copy of Erica Sadun's mdhelper (binary file) command line utility, and run it from the PC you sync your laptop with like so:
mdhelper -files "AddressBook.sqlitedb" -extract -glob
This will create a "~/Desktop/Recovered iPhone Files" directory containing a file called AddressBook.sqlitedb, which you can access directly or query using your programming language of choice.
If you don't trust downloading and running binary files without knowing what they do, you can look at the source on Github and compile it yourself.
the SQL database can be extracted from an iphone backup. I used this software to grab mine and the SMS database.
If you have lots of images/videos in camera roll it can take a while to run.

Yeah sorry abt that. ok thanks probably i will create a new database using AddressBook Apis

You can also take a backup of your iphone and than use one of tools discribed here to identify the file you need.
