feature request: example of configuration to run tests on ios

[stchar]

Hi, first of all I want to thank you for creating this project. It saves me a bunch of time in learning and setting up the environment. Its is awesome, thank you.

As far as I understand the project contains configs to run tests on android devices and emulators. I tried to update it for ios however I'm not able to run it. If you could share the solution for ios devices it would be perfect. Please let me know if you need any assist.
