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 trying to make a detailView to my tableView and I am not getting any results. Now I am wondering is that because I am doing something wrong with my code, or is the data nto being stored properly.

How can I see what is stored in the app's CoreData database?

Answer 1

Here is my solution(works on iOS 9):

I use an automator/bash script that open the database in sqllitebrowser. the script finds the latest installed app in the simulator. Instructions:

1. Install DB Browser for SQLite (http://sqlitebrowser.org/)
2. Create new workflow in Apple Automator.
3. Drag "Run Shell script block" and paste this code:

cd ~/Library/Developer/CoreSimulator/Devices/ cd `ls -t | head -n 1`/data/Containers/Data/Application  cd `ls -t | head -n 1`/Documents open -a DB\ Browser\ for\ SQLite ./YOUR_DATABASE_NAME.sqlite 

4. (Optional) Convert this workflow to application, save it and drag it to your dock. To refresh the database just click on the app icon.

Answer 2

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.
