if (weatherData.currentTemperature == null) {
      print("apiden currenttemeperatu boş gelyio");
    }

Please check your log, i guess your iPhone app don't have network permission.
When iPhone ask you that your iPhone app need network permission, you need to allow that.

Please check that you api endpoint uses https, because http connections are disabled by default.
