QML: module "QtQuick.Controls" plugin "qtquickcontrolsplugin" not found on iOS

Hello,

I wanted to start developing mobile apps with Qt and QML, because one of mine desktop applications needs an mobile app.

This is why I am experimenting with QML at the moment.

But as soon as I want add these line in top of my .qml file,

Code:

---

import QtQuick.Controls 1.4
import QtQuick.Controls.Styles 1.4

---

I get this error when I run the app with the iOS-Simulator:
QQmlApplicationEngine failed to load component
qrc:/main.qml:3 module "QtQuick.Controls" plugin "qtquickcontrolsplugin" not found
and the screen in the iOS-Simulator stays black.

When I try to start it with the "Desktop-Kit" it runs fine.

What could be the problem, is it not possible to use QtQuick Controls with iOS?
