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.

回答1:
In Xcode go to the Xcode menu->Open Developer Tool - IOS Simulators. Choose simulator and then go hardware->device->manage device.
If the troubled device shows in the left column, delete it. Then add the device back from the '+' button. If it wasn't there in the first place, simply add it using the '+' button.
回答2:
From terminal, get the list of devices with:
xcrun simctl list
This will show you your list of devices with "Shutdown" or "Booted". You'll likely see your device is in a "Booted" state. You can shut it down with:
xcrun simctl shutdown <simulator id>
Where <simulator id>
is the name of the device in the list. For example:
xcrun simctl shutdown "iPhone 6 Plus"

I encountered similar problem. Got it resolved. Below are steps to fix it.
Open Simulator
Select Hardware -> Device -> Manage Devices...
This will opens a window containing list of simulator devices
Delete simulator that prompts error by right click on it.
Again add simulator by clicking '+' button onto right corner of window
- Select Simulator Name, Device Type and iOS Version

I solved this issue by this way:
- Open Xcode
- Goto Xcode menu > Open Developer Tool > iOS Simulators
- It will run Simulator with error
- Goto Hardware > Device > Manage Device
- Add needed simulator to your system

Restarting the computer solved this for me. I restart very rarely so I would never normally have thought of this!
回答6:
Applicable for Xcode 6.x, here is the command-line solution (type on Terminal window):
- xcrun simctl shutdown
- xcrun simctl erase
- 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
回答7:
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.
回答8:
Quit Xcode and Simulator.Then rebuild build and run.
回答9:
Quit iOS simulator. Change Target iOS Simulator to any other iPhone or iPad and then run app. Its working for me.
回答10:
Happened to me also, run an xcrun simctl shutdown <simulator uid>
and got the simulator working again.
回答11:
This will kill any booted/running simulators even if the .app is not shown:
xcrun simctl shutdown all
回答12:
I had the same problem. I reset the settings on the iOS Simulator, and it was fine again.
iOS Simulator -> Reset Content and Settings...
回答13:
I don't know if this is any help to you guys but in my case I had this issue when I had a simulator window already open and I tried the command line invocation of simulator to run a .app file.
/Applications/Xcode.app/Contents/Developer/Applications/iOS\ Simulator.app/Contents/MacOS/iOS\ Simulator -SimulateApplication ${pathToMyApp}/MyApp.app/MyApp
I just quit all of my simulator windows and ran the command again. That fixed it.
回答14:
When I came to this issue,I tried to tackle it as follows:
cd /Applications/Xcode.app/Contents/Developer/Applications
In Terminal: open -n Simulator.app.Click Ok.
- Then go to Simulator->hardware->Device choose another device,not the same type of already opened one.(e.g, the first one is iphone 6 the new one could be iphone 7)
4.Then there will open a new simulator.
Hope this will help you.

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.
