From reading the error message it says Please use cordova platform add <platform>

So I run cordova platform add ios

I get

Adding ios project...
Unable to load PlatformApi from platform. Error: Unhandled "error" event. (Does not appear to implement platform Api.)
Error: Project already exists

I have no idea what to do? Ive been hitting my head against the wall for a couple hours on this.

Hi ,

Remove the platform which you try to run on it (browser, ios, android, and etc.)
cordova platform rm browser

Add the platform again
cordova platform add browser

You can run
cordova run browser

I got myself in quite the pickle. To get out of it I took some drastic measures.

I updated the iOS platform from 3.9.0 to 4.5.4
I updated Cordova to 8.0 and Ionic to the latest
I then updated my operating system from El Capitain to Sierra
I updated X code to 9.2

I then did

  • rm -rf node_modules/ platforms/ios/
  • npm i
  • ionic cordova build ios
  • ** BUILD SUCCEEDED **

Not sure how I created such a mess but glad its figured out
