How can I check what is stored in my Core Data Database?

Question

I am making an app that relies on Core Data. I am able to enter data into a text field and store it.

But I need to know if the data is being stored.

I am try

Answer 1

As Far as macOS Sierra version 10.12.2 and XCode 8 is concerned

The folder should be here:

/Users/$username$/Library/Developer/CoreSimulator/Devices/$DeviceID$/data/Containers/Data/Application/$ApplicationID$/Library/Application Support/xyz.sqlite

To get the device id - Open terminal and paste:

instruments -s devices

Answer 2

An easy and convenient way to locate the Core Data database and to view and analyse the content, is by using a tool like Core Data Lab.

1) Get path of sql database of your simulator.

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSLog(@"%@", [paths objectAtIndex:0]);

2) Open Finder. Press Cmd+Shift+G. Paste something, that you got from paragraph 1. Ex:

/Users/USERNAME/Library/Developer/CoreSimulator/Devices/701BAC5F-2A42-49BA-B733-C39D563208D4/data/Containers/Data/Application/DCA9E9C7-5FEF-41EA-9255-6AE9A964053C/Documents

3) Download in AppStore programm like SQLPro.

4) Open file in folder with name "ProjectName.sqlite".

GOOD JOB! You will see something like this:

Answer 4

Swift 4, 5

Add this line in AppDelegate >> didFinishLaunchingWithOptions function:

print("Documents Directory: ", FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).last ?? "Not Found!")

Your modelName.sqlite file will be there.

You can open it with any SQLite browser tools like http://sqlitebrowser.org/ that is free.

Answer 5

Since no one has pointed out, how to get the sqlite DB from the physical device.

Here is how to get the application data:

Browse the files created on a device by the iOS application I'm developing, on workstation?

After opening the .xcappdata file (right click > Show Package Content), you will usually find the DB file at the AppData/Library/Application Support folder.

Answer 6

The other solutions are either old or does not direct you easily or quickly to the SQLite files, so I came up with my own solution using FileManager.SearchPathDirectory.applicationSupportDirectory that gets the exact path where the sqlite file will be.

func whereIsMySQLite() {
    let path = FileManager
        .default
        .urls(for: .applicationSupportDirectory, in: .userDomainMask)
        .last?
        .absoluteString
        .replacingOccurrences(of: "file://", with: "")
        .removingPercentEncoding

    print(path ?? "Not found")
}

whereIsMySQLite() will print the path which you can simply copy-paste on your Mac here:

Finder > Go > Go to folder
