    Yeah, there must be something qmake does which makes the difference...

      @_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"


              Be aware of the Qt Code of Conduct, when posting : https://forum.qt.io/topic/113070/qt-code-of-conduct


              Q: What's that?
              A: It's blue light.
              Q: What does it do?
              A: It turns blue.

                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
