Hello everybody,

I want to run a project on iOS device rather than the simulator.

First of all my system information is:

Cordova CLI: 4.3.1
Gulp version:  CLI version 3.8.11
Gulp local:  
Ionic Version: 1.0.0
Ionic CLI Version: 1.5.5
Ionic App Lib Version: 0.2.2
ios-deploy version: 1.7.0 
ios-sim version: 3.1.1 
OS: Mac OS X Yosemite
Node Version: v0.10.35
Xcode version: Xcode 6.2 Build version 6C131e
When I execute ionic run ios --device I get the following error. It’s not so long, so, I’m pasting it all:

You may not have the required environment or OS to run this project
Any help will be appreciated. Thanks.
              
the code signing keys are not configured in xcode. first do ionic build ios and then open the xcode project. In the general settings you need to add the keys.
Login using your apple developer credentials on apple developer portal and search for provisioning.
IOS is not like android. You need to sign the app and provision the device before running.
              
@gaurav_ch  Thank you for pointing out the signing key problem. I solved the issue. Here are the steps I followed:
run ionic platform remove ios
open config.xml and edit the id attribute of the <widget> tag. (e.g.  id=“com.mycompany.todo”)
go to apple developer portal and register a new App ID (e.g. Name: todo, Bundle ID: com.mycompany.todo)
in the apple developer portal create a provisioning profile for that app. I created a develoment profile.
connect your iOS device to your computer via USB
open the terminal and cd to the project’s root directory and run ionic platform add ios and then run ionic platform run ios --device
That’s all.
Note: Before following the steps above I opened the Xcode project located in platforms/ios/ and in the general settings sections I clicked a button like ‘fix code signing issues’. I don’t exactly remember what the label of the button was saying. But after clicking that, a popup window in Xcode appeared asking me to login to the developer center with my credentials. After establishing the connection it tried to import something but failed. Then I thought that I should create the app on the developer portal first. So, did I and it worked.
