'"Ionic 3 App" may slow down your iPhone' alert


I am facing this issue when trying to start the app with Ionic3. Is anyone facing the same issue? Is there any fix for this?


I had the same issue with Ionic 2.

Adding :

"cordovaPlatforms": [
      "platform": "ios",
      "version": "4.3.0",
      "locator": "ios"

to the package.json file, and :

<engine name="ios" spec="~4.3.0"/>

to the config.xml file solved the issue.


I saw this response on stackoverflow, but I couldn’t understand why to use version 4.3.0, because as far as I know this is the cordova version and on my machine I am using 6.5.0


This is the version of cordova-ios which has a different version than cordova (which is the command line interface).


Ah, great, thanks for the explanation!
