Ionic emulate ios - Error

Question

I'm getting this following error after I ran my app on my own ios device.

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

Error: /Users/cauealmeida/Documents/jobs/dev/ionic-maptest/map-test/platforms/ios/cordova/run: Command failed with exit code 2

I've tried with ionic emulate ios -cls from different projects and the same error is shown.

What am I missing?

Answer 1

Here are the steps you can use to correct this issue:

1) Empty the 'platforms' folder in your Ionic project

2) Re-run ionic platform add ios, ionic build ios, and ionic emulate ios without sudo

3) Still getting a permissions error, make sure all the files in your user's home folder actually belong to that user by running

sudo chown -R username /Users/username

Answer 2

We fixed this using the SO answer here, which was just to Reset Content and Settings in the Simulator menu.

Answer 3

You need to download ios simulator. Go to xcode and download ios 9 or other simulator.

you also need to install ios-sim using your terminal.

sudo npm install -g ios-sim

also check and confirmed your device is connected properly. connected device you see in xcode window
