    Are you using qmake/qtcreator?

    Looks the same for me:

      @_eph Yes, it's a qmake project ("Qt Quick Application - Empty" template with changes in main.cpp and main.qml), I build it using both Qt Creator and XCode, and see no difference - it work as expected.

        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).

                              @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
