Unable to boot device in current state: Booted

Ios8 Problem Overview

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.

Ios8 Solutions

Solution 1 - Ios8

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.

Solution 2 - Ios8

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

Solution 4 - Ios8

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

xcrun simctl shutdown all

Solution 5 - Ios8

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

Solution 6 - Ios8

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

Solution 7 - Ios8

2022 fix

I found solution. Simulator -> Preferences -> Simulator lifetime: When Simulator starts boot the most recently used simulator I unchecked.

Solution 8 - Ios8

This solution worked for me Go to Xcode -> Open Developer Tool-> Simulator -> uncheck the option when simulator starts boot the most recently used simulator

Solution 9 - Ios8

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

Solution 10 - Ios8

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.

Solution 11 - Ios8

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

Solution 12 - Ios8

Quit Xcode and Simulator.Then rebuild build and run.

Solution 13 - Ios8

Happened to me also, run an xcrun simctl shutdown <simulator uid> and got the simulator working again.

Solution 14 - Ios8

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.

Solution 15 - Ios8

I had the same problem. I reset the settings on the iOS Simulator, and it was fine again.

iOS Simulator -> Reset Content and Settings...

Solution 16 - Ios8

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.

Solution 17 - Ios8

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.

Solution 18 - Ios8

I had the same problem. I reset the settings on the iOS Simulator, and run an xcrun simctl erase all and got the simulator working again.
