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

I encountered similar problem. Got it resolved. Below are steps to fix it.

1. Open Simulator

2. Select Hardware -> Device -> Manage Devices...

3. This will opens a window containing list of simulator devices

4. Delete simulator that prompts error by right click on it.

5. Again add simulator by clicking '+' button onto right corner of window

6. Select Simulator Name, Device Type and iOS Version

Answer 2

Quit Xcode and Simulator.Then rebuild build and run.

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

Answer 4

When I came to this issue,I tried to tackle it as follows:

1. cd /Applications/Xcode.app/Contents/Developer/Applications

2. In Terminal: open -n Simulator.app.Click Ok.

3. 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.

Answer 5

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.

Answer 6

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

iOS Simulator -> Reset Content and Settings...
