iPhone Simulator problem – Corrupted Device

The system I inherited kicks off builds via Jenkins, so I saw this error in the Jenkins output

An error was encountered processing the command (code=146):

  • This means the virtual device, got corrupted and needs to removed and added back in, doing it command line often doesn’t work.
    1. Go to the VM in question, launch the iPhone simulator.  You will probably get a pop up (the “device” trying to display with a message notification that has the unable to erase message.
    2. Switch to a different device, by going to the menu for the Simulator and clicking on Hardware -> Devices and choosing any other device.
    3. Then go to Hardware -> Devices -> Manage Devices (button of the device list)
    4. When the pop up appears, select the problem device and choose delete (if you son’t switch devices first (step 2) this device will be active and you can’t delete it)
    5. Then hit the plus key “+” (at the bottom) and then create a new version of the device you just deleted (in my case I had to delete an iPhone 6 and create a new iPhone 6)
    6. You’re done, just update any files that might use the unique identifier in them
