Where does the iPhone Simulator store its data?

Solution 1:

For Xcode6+/iOS8+

~/Library/Developer/CoreSimulator/Devices/[DeviceID]/data/Containers/Data/Application/[AppID]/

Accepted answer is correct for SDK 3.2 - SDK 4 replaces the /User folder in that path with a number for each of the legacy iPhone OS/iOS versions it can simulate, so the path becomes:

~/Library/Application Support/iPhone Simulator/[OS version]/Applications/[appGUID]/

if you have the previous SDK installed alongside, its 3.1.x simulator will continue saving its data in:

~/Library/Application Support/iPhone Simulator/User/Applications/[appGUID]/

Solution 2:

There is another (faster?) way to find where your app data is without Terminal:

1. Launch the app in the simulator
2. Open Activity Monitor
3. Find the name of your app in the CPU tab
4. Double-click it and open the "Open Files and Ports"
