The vapor app will just call SIM control to like find out what simulators you got running and then save the request to the watch as a file. The first challenge was post thinking, okay, so it's gonna be an app, but it doesn't fit into the sandbox because it needs to read the system log. And so I had to for the moment leave aside command line tools, something that I felt strongly for the possibility to work with iOS apps, watch OS apps and TV apps.
