Issues with Adding IOS Platform


I have been having a horrible time with getting my app built to iOS. I have gotten close a few times, but each time something seems to stop me. I decided to try the entire process from scratch, so I deleted the platforms/ios directory, and I tried to do a new ionic platform add ios and this is the error I am getting now. Can anyone provide any thoughts or assistance?

Seems that just deleting the platforms/ios folder was not right, instead I did an ionic platform remove ios then retried the add ios, and it seemed to work. Go figure.
