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.

Screenshot for error

I'm going to assume this is a bug in XCode; please file it at bugreporter.apple.com. It is a beta after all; the whole point is to find these bugs now. — nneonneo, Jun 10 '14 at 07:20
restarting Xcode + simulator helped on me. that is a bug. you don't need to find simplier solution, because that feature won't be in the final release. — holex, Jun 19 '14 at 13:20
It does. Using build 6.1 (6A1052d). Tried it twice, downloading the installer from the dev site twice. — Alex Zavatone, Nov 21 '14 at 23:17
Embarrassingly, I've also encountered this when I accidentally set a breakpoint in Xcode without realizing it. So, something else to check. — kiminoa, Mar 17 '15 at 17:10

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.

In Xcode 6 the devices manager went to menu "Window" -> "Devices". – Lars Blumberg Oct 17 '14 at 15:32

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"

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

xcrun simctl shutdown all

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!

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.

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

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.

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.

With simulator opened, select "simulator preferences" and disable (simulator lifetime),so it doesn't use the same simulator used before the default. Resolved for me.
