ionic-framework: bug: BUG can't open ios simulator with xcode 7

Solved it with : http://zacvineyard.com/blog/2015/11/ionic-invalid-device-state-error-with-xcode-7-solved

Looks like the command line tools with Xcode weren’t installed. Make sure they’re install by opening Xcode or running xcode-select --install from the command line.

hey guys!

I have the same problem when I try to emulate iOS platform

** BUILD SUCCEEDED **

No target specified for emulator. Deploying to iPhone-SE, 10.0 simulator

An error was encountered processing the command (domain=com.apple.CoreSimulator.SimError, code=163): Invalid device state

An error was encountered processing the command (domain=com.apple.CoreSimulator.SimError, code=163): Invalid device state

Error: ENOENT: no such file or directory, stat ‘/Users/Leith/Library/Logs/CoreSimulator/81DA68A9-07E9-4202-B985-8D9B106F458E/system.log’

bash-3.2#

I tried to looking for any solution about this…but I can’t find something good.

Any idea? Thanks!

Ok this is what worked for me.

1. Uninstall/ Fresh Install Xcode.
2. Follow this guide to use npm without sudo: http://www.johnpapa.net/how-to-use-npm-global-without-sudo-on-osx/
3. run: npm -g install ios-sim

Having the same problem, and no solution found after read the whole thread.

¿Any help?

Alright guys, I went through all of these suggestions and none of them helped me. For those unlucky few that still get

No target specified for emulator. Deploying to iPhone-6 simulator
An error was encountered processing the command (domain=com.apple.CoreSimulator.SimError, code=159):
Invalid device state

Open your Xcode project, then run it on the iPhone 6 emulator. After doing that step, I was able to use ionic emulate ios and ionic emulate ios -lcs ಠ_ಠ

@BenjaminConant I’m seeing the same issue, the emulator doesn’t start properly. The project seems to build, then starts a blank window, and after a while the console exits with:

No target specified for emulator. Deploying to iPhone-6s-Plus, 9.3 simulator
An error was encountered processing the command (domain=com.apple.CoreSimulator.SimError, code=159):
Invalid device state
An error was encountered processing the command (domain=com.apple.CoreSimulator.SimError, code=159):

Error: ENOENT: no such file or directory, stat '/Users/[username]/Library/Logs/CoreSimulator/8776EAE5-33FF-40FC-B75D-4204851C010E/system.log'

Recursive chowning hasn’t helped, nor sudo npm installing ios-sim and ios-deploy. Given it’s a first run for me on ios development, it might be that I’m just missing something, or it could be a real issue for the few of us.

thanks @oneboxteam, http://zacvineyard.com/blog/2015/11/ionic-invalid-device-state-error-with-xcode-7-solved it work:)

Hi all,

Have tried everything in this thread and still getting the same issue … I can open up the project in xcode and run the emulator from there and everything works great. I cannot, however, open the emulator from the terminal with ionic emulate ios … when i do run ionic emulate ios i get

** BUILD SUCCEEDED **

the emulator opens but is just a black screen and then after a while the terminal logs

No target specified for emulator. Deploying to iPhone-6 simulator
An error was encountered processing the command (domain=com.apple.CoreSimulator.SimError, code=159):
Invalid device state

here is my ionic info

ordova CLI: 6.0.0
Gulp version:  CLI version 3.9.0
Gulp local:
Ionic Version: 1.2.4
Ionic CLI Version: 1.7.14
Ionic App Lib Version: 0.7.0

ios-sim version: 5.0.6
OS: Mac OS X El Capitan
Node Version: v4.0.0

Anyone else seeing behavior like this or have any ideas? Would be much appreciated!

@oneboxteam’s link didn’t work for me. But running “ionic state reset” did.

You should launch the xcode ,and select /platform/ios/xxxx.xcodeproj path and build on ur iphone or launch the simulator , and run the terminal ,then it works
