To run these tests you will need Python 2 and pipenv installed. Once you have these, make sure you're in the SyncIntegrationTests directory and run the following:

$ pipenv install
$ pipenv run pytest

The tests will build and install the application to the simulator, which can cause a delay where there will be no feedback to the user. Also, note that each XCUITest that is executed will shutdown and erase data from all available iOS simulators. This assures that each execution starts from a known clean state.
