This guide discusses how you many identify the various iOS devices connected to your workstation and the different iOS simulators available for running Calabash tests.


It is possible to run Calabash tests on specific simulator instances or device by providing the device identifier when running the tests. There are two ways to list available devices/simulators and their corresponding device identifier.

  1. At the command line.
  2. Using Xcode.

This section will discuss each of these techniques.

Identifying Available Devices & Simulators at the Command Line

To see a list of all known iOS devices and simulators, start up Terminal and type the following:

Xcode provides another way to obtain a list of devices and their device identifiers. Once Xcode is running, select Window > Devices, or press Shift-Command-2:

Xcode will present a window showing the simulators and devices. Select a device/simulator from the list on the left. The right hand side of the window will be updated to show the device identifier:
