I did try to emulate the project ionic-angular-cordova-seed-master but the ios emulator don’t appear after I enter the commad: cordova emulate ios. , i.e, nothing happens.

I just delete de directory plataform/ios and run `cordova build ios` .  
After this, when I run the command cordova emulate ios, the following error occurs:

```

Hmm, so in the first example it says `Running on emulator for platform "ios" via command "/dados-usr/trabalho/ionic-angular-cordova-seed-master/platforms/ios/cordova/run" --emulator` but nothing happens? Strange.

What happens if you try without `sudo`?

Also after deleting platform/ios, did you do `cordova platform add ios` again?

EDIT: Looking into it a little more, what does `ios-sim -version` give you? And what version of Cordova are you using?

I found a solution. But I don’t know if this solution is correct.  
Before I run the command `cordova emulate ios`, I did need start XCode application and start a emulator from it. Then, when I run `cordova emulate ios` the XCode application was invoked and the emulator appears.  
In this page, the instructions isn’t so clear about this: [https://cordova.apache.org/docs/en/2.9.0/guide\_cli\_index.md.html](https://cordova.apache.org/docs/en/2.9.0/guide_cli_index.md.html)

Is this method correct? Do I must execute XCode’s emulator before?

```
duly-imac:ios eldontc-std$ ios-sim --version
1.8.2
duly-imac:ios eldontc-std$ cordova platform add ios
Platform ios already added
duly-imac:ios eldontc-std$ cordova emulate ios

@Ciraxis

My cordova version is 3.3.1-0.3.1 and I’m not run on Mavericks, but on Mountain Lion, 10.8.5.

```
duly-imac:ios eldontc-std$ cordova -version
3.3.1-0.3.1

Is it possible it’s something like this: [http://stackoverflow.com/a/16739338/1091751](http://stackoverflow.com/a/16739338/1091751) ?

My other thought is that since you ran everything as `sudo` perhaps permissions somewhere got screwed up? AFAIK you won’t need to run as root for anything cordova related, perhaps try cleaning out the project directory and re-installing without `sudo` or taking a look at the project permissions?

Thanks Tim, I happened upon this thread for similar reasons and the `sudo` thing did it for me.

Just thought I’d add in my recent experience with a similar error. Turns out it was due to my running in a tmux session.

This fixed the problem for me:

1. Open simulator directly
2. From the menu: iOS Simulator -\> Reset Content and Settings… then hit Reset
3. re-run your project

Seems like I had same problem. Make sure you have access rights to your project folder and to all it’s nested objects.  
Granting read/write permissions to myself fixed this issue for me.

Running into this issue after first installation - **iOS Simulator failed to install the application.**  
I tried resetting simulator content and settings but that didnt help. Any thoughts?

In my case it was sudo ing the iOS add caused the issue. do this,

1. sudo cordova platform rm ios
2. cordova platform add ios
3. build and emulate

Do not add the platform with sudo!
