    @_eph Here is an example of Qt cmake QML project for iOS with QQuickView:

    https://github.com/forexample/qt-ios-examples/tree/master/qml-custom-property-types

    In main.cpp it imports some plugin called "QIOSIntegrationPlugin". May be you should import it too?

      @_eph Please note that main() in iOS case is called qtmn(). It's not the real main() and it will be called from this plugin after some initial setup (as I think).

        @KoneTaH Yeah, that doesn't work (it's looking for undefined _main).

        Btw. I needed to force load the ios plugin and use _qt_main_wrapper for the app to work at all.

          Yes, so if I just create simple qml - using your example:

          #import <QQuickView>
          #include <QtPlugin>
          Q_IMPORT_PLUGIN(QtQuick2Plugin)
          #endif
          
          int main(int argc, char *argv[])
          {
              QGuiApplication app(argc, argv);
              
              QQuickView *view = new QQuickView;
              view->setSource(QUrl::fromLocalFile("/tmp/simple.qml"));
              view->showFullScreen();
              
              return app.exec();
          }
          

          and the QML:

          import QtQuick 2.0
          
          Rectangle {
              id: page
              width: 300; height: 200
              color: "yellow"
          
              Text {
                  id: helloText
                  text: "Hello world!"
                  y: 30
                  anchors.horizontalCenter: page.horizontalCenter
                  font.pointSize: 24; font.bold: true
              }
          }
          

          This is the result:

          @_eph
          I would suggest using a proper Windowas the root item instead of a rectangle or something like that
          https://doc.qt.io/qt-5/qml-qtquick-window-window.html

          and do not set a width or height for the root item. it should scale automatically - except for "safe zones"

            Hi @_eph , you need to have proper splash screen, otherwise your app comes like this, so every Iphone has a different size for the splash screen, so you need to prepare a splash screen with respect to the device you are deploying on and after that you need to include it in a file called info.plist, same is the case with app icons also.

            For more info you can have a look into this: -[https://doc.qt.io/qt-5/ios-platform-notes.html]

            For info on the sizes you can have a look at this:- [https://developer.apple.com/design/human-interface-guidelines/ios/icons-and-images/launch-screen/]

            I guess once you have proper splash screen,the app will cover the complete Iphone screen.

              @J.Hilk Makes no difference the QML is always contained in the same window/rectangle you see on the first screenshot.

                @Shrinidhi-Upadhyaya Hm, I don't really see connection between the launch image (splascreen) and the actual app since you don't need that kind of thing when you use Qt Creator and qmake but I will try it anyway. Thanks

                  @_eph Do you have some minimal CMake project with this issue somewhere in public? Usually I don't use CMake, but I can take a look (as well as others, I think).

                    @Shrinidhi-Upadhyaya OMG, you are the man! It really helped, I can't believe it lol. Adding a dummy launch storyboard made it go fullscreen... Unbelievable

                      @KoneTaH I don't unfortunately - it's a very complex project with lots of subprojects and libraries. I could probably share the toolchain file but looks like I might have figured it out thanks to @Shrinidhi-Upadhyaya
