Running Appium deletes the iOS simulators created in Xcode

Mac OSX Mavericks 1.3.3
Xcode 6.1

PROBLEM: Whenever Appium physically launches the simulator all of my iOS simulator devices are deleted, except the iOS sim described in desired_caps (the sim Appium physically launches)

  • Open Xcode
  • Observe I only have iPhone6 iOS8.1 simulator available to run my project on
  • Click Window > Devices and observe I only I only have iPhone6 iOS8.1 available, all of my other devices are missing
  • Manually create one or more additional devices, such as iPhone 4S iOS7.1
  • Can successfully launch my app on the newly created sims directly from Xcode without any problem
  • Can exit / restart Xcode, and all of the sims are still physically present, still no issues
  • Open with iPhone 6 iOS8.1 with prelaunch enabled
  • Correct sim is successfully launched
  • Open Xcode and observe all of my other sims have been removed

This appears to be the pertinent details from the log:

I can reproduce by changing desired_caps to use iPhone 4S iOS7.1 and then Appium will delete my iPhone6 iOS8.1 sim instead.

I’m facing the same issue. Did you ever find a resolution?

My current solution: Only test on a single iPhone6 iOS8.x sim.

At the time I write this I haven’t bothered to try other sims at this time, nor real hardware devices.

That’s too bad. I have OSX Jenkins nodes I’d like to use for both iPad and iPhone sim testing, but switching between the 2 devices is proving to be impossible.

Eventually that will be my plan, too. However, I’m still in the test case design phase and learning / exploring / ironing out general issues with Appium against a single sim has proven a big enough challenge thus far.

I recently started using Appium for iOS.
One of the server arguments “Isolate Simulator Device” would delete all of the devices in the Core Simulator folder except the one which you are testing (the one provided in the Capabilities). I have been using Appium 1.3.5 and 1.3.6. Seems like the issue is fixed as your devices wouldn’t disappear unless you have this argument selected in the Appium app or are providing it while running via node.
You guys may already know this but was just trying to help just in case if some other newbie like myself faces the problem.
