问题
I've setup some XCTest unit tests for my application and would like every time I run tests for it to run in a brand new install of the application. Currently when I run subsequent tests it runs the tests in the same application that was run before which has a lot of state information already changed by the previous tests.
Is there a way to indicate that when you run unit tests that it should run the tests on a fresh version of your application?

Maybe this works, but only for Simulator.
In Product > Scheme > Edit Scheme...
xcrun simctl is command line utility to control the iOS Simulator.
This uninstalls com.yourcompany.AppName application from booted simulator before running tests.
I don't know how to do like this for real device :(

In addition to @rintaro's answer, if you set "Provide build settings from" to your app, you can add a generic command, which will keep working when your bundle id changes:
xcrun simctl uninstall booted ${PRODUCT_BUNDLE_IDENTIFIER}
