Origin http://localhost:8080 is not allowed by Access-Control-Allow-Origin || iOS iPhone problem

Hi,
I have created an application that connects to 3rd party API. In android it works perfectly, but in iOS it produced the issue:

Origin http://localhost:8080 is not allowed by Access-Control-Allow-Origin.

It is really weird, I’m running the app on the device and using cordova-plugin-http. Any idea what could produce such issue ?

Maybe this can help you:
