I'm trying to retrieve some data from server, using ionic 4, the app actually works fine on browser but when I use a real device it doesnt work, after hours searching on the internet, I found a solution that I have to install a Cordoba pluging called cordova-plugin-whitelist,when I added this plugin the app worked fine on android device but not is IOS device, I checked capacitor DOC, then I found that I have to run this command :
ionic cap sync
after thise commande is executed,I got this message :
> capacitor add ios

```
if you noticed on the bottom of the message you'll finde a wierd message:
Found 1 incompatible Cordova plugin for ios, skipped install, is that normal ?
cordova-plugin-whitelist doesn't support iOS (because it's not needed). The message might be a bit missleading.
Just check the plugin code, it doesn't have an iOS folder
