How to browse Core Data in my app running on my iPhone?
If you don't need to see this information in real time, Xcode's Organizer will allow you to download the sandbox directory of any development apps on the device:
- Connect the device to your Mac.
- Open Xcode's Organizer window to the Devices tab.
- In the source list, select the Applications item under your device.
- Pick your application from the list in the main part of the window.
- Use the Download button at the bottom of the window to copy the sandbox directory to your Mac.
- The data is downloaded in a package, so right-click it in the Finder, and select Show Package Contents.
From there, any of the many tools available to open/inspect Core Data storage or SQLite databases should work for you.
You can also use this package when running your app in the simulator or on the device to force the run into a known state. That can be tremendously helpful when debugging things like Core Data migrations or strange invalid states.
To view Coredata from a device :
Plug in the device -
Start Xcode
On the top Xcode menu -
Select Window -
Select Devices -
Select your device -
Select the app -
Select the settings icon (gear shaped symbol to the right of "+ -") -
Select Download container -
Save it to a folder -
It will have an extension of ".xcappdata" -
Open FireFox
(If you dont already have it - get the FireFox SQLite Manager browser plug in)Select the SQLite Manager icon on the top right (looks like a barrel with stripes)
Select the open folder icon
change Format [SQLite DB files] to All Files
Browse to and Select your database
In addition to the tables and columns (sorry - Entities and Attributes ) you created in Coredata - you will see a few extra columns created by CoreData itself.
Hope this helps somebody.It's a bit of a bear, but worth the trouble to see your database "in the flesh"
