Reset iOS Simulator application data to run app for first time

I just finished writing some code that checks if it is the first time the app is running then display a message, if it is not the first time then display another message..

How do you reset the simulator on Xcode so that I can test the app when it runs the first time?

I tried cleaning the build folder but it didn't work..

Solution 1:

In the iOS Simulator, press iOS Simulator in the menu at the top of the screen, and press 'Reset Content and Settings...'. This will clear the entire simulator.

Or, on the home screen of the simulator, uninstall the app in the same way you would on a physical device, by pressing and holding on the application icon until an 'x' appears in the top left, and press the 'x', and select 'Delete' from the alert view. This will clear all data associated with a single app.

Then do a clean, build and run.

Edit:

As of Xcode 11+ Simulator, this is under Device > Erase All Content and Settings

Solution 2:

The correct way to do this in XCode is: (Simulator must be shut down first)

xcrun simctl erase <device UDID> or xcrun simctl erase all

To find out the UDID use:

xcrun simctl list
