Platform add error with ionic 2

i am having an issue in adding platform in ios. I have created the project and then trying to find my platforms folder which i couldnt find.
i tried adding the platform which says, platform was already added. but no platforms folder was there. so i did platform remove and then added platform but still cant find platforms folder.

while adding platform the id of the app is com.ionicframework.remedyapp229055 but the ionic 2 project which i added is com.ionicframework.ion1912063. when i searched for remedyapp229055, taking me to other ionic project in my system.

Here is my ionic info:
