Unable to boot device in current state: Booted

Question

Any guess on "Unable to boot device in current state: Booted" error in Xcode6 beta while running (build+run) project in Simulator. I am just running my existing project in Xcode 6 I found above message. I tried cleaning, deleting of the derived data, even restarting the simulator doesn't work. Finally i restarted my Xcode 6 then it is working. Any simpler way to resolve the error instead of restarting your xcode6.

Answer 1

Restarting the computer solved this for me. I restart very rarely so I would never normally have thought of this!

Answer 2

I just quit the Xcode and then remove all derrived data. Then relaunch Xcode and do cleaning, build it wait for it's indexing complete then run the project and issue get resolved.

Answer 3

Quit iOS simulator. Change Target iOS Simulator to any other iPhone or iPad and then run app. Its working for me.

Answer 4

This will kill any booted/running simulators even if the .app is not shown:

xcrun simctl shutdown all

Answer 5

Applicable for Xcode 6.x, here is the command-line solution (type on Terminal window):

1. xcrun simctl shutdown
2. xcrun simctl erase
3. open /Contents/Developer/Applications/iOS\ Simulator.app

Where is the id of the device you want to launch. You can get the list of devices and their UDIDs here:

• xcrun simctl list

Answer 6

Delete all devices on Simulator->Hardware, and add them back, not working :(

Bug or not, restarting Xcode doesn't work for me; could not get Simulator back to work until restarting my computer and it seems the adding-back had failed before restarting.
