Running simulator with error: No template

Question

I run the following command to launch an iOS simulator using Xcode

 xcrun instruments -w 2E755803-3DFD-4722-B6B7-25498BCFF551

and with an error

Instruments Usage Error : No template (-t) specified
instruments, version 7.2 (59503)
usage: instruments [-t template] [-D document] [-l timeLimit] [-i #] [-w device] [[-p pid] | [application [-e variable value] [argument ...]]]

so what is the template that is required here?

Answer 1

I walked around it, first starting up another device, and then the one I needed.
