Same here. I didn't see these issues with Qt 6.4.1, but with 6.7+ building for iOS (sim and device) takes around 2 minutes after all the warnings are logged.
Any progress on this?

@Sammasas
I didn't find a universal way, but with an QJNIObject and objective c it works now. Java with JNiObject:

package Klingelball; import android.content.Context; import android.content.res.Configuration; import android.util.DisplayMetrics; import android.view.WindowManager; public class AndroidSettings { public static float getFontScale(Context context) { //return getResources().getConfiguration().fontScale; Configuration configuration = context.getResources().getConfiguration(); // Get the font scale from the configuration float fontScale = configuration.fontScale; return fontScale; } }

It's important that the file is under src/mypackage.

.cpp file:

#ifdef Q_OS_ANDROID QJniObject context = QNativeInterface::QAndroidApplication::context(); if(QJniObject::isClassAvailable("Klingelball/AndroidSettings")) { QJniObject androidSettingsJavaObject = QJniObject("Klingelball/AndroidSettings"); fontScale = new float(androidSettingsJavaObject.callStaticMethod<jfloat>("Klingelball/AndroidSettings", "getFontScale", "(Landroid/content/Context;)F", context.object<jobject>())); qDebug() <<"Font scale:" << *fontScale; setup_fontAndroid(*fontScale); } else { qDebug() << "JAVA CLASS UNAVAIABLE!"; fontScale = new float(1); setup_fontAndroid(*fontScale); } #endif

iOs with objective-c:
.mm file:

include "iOSSettings.h" #include <UIKit/UIKit.h> int iOSSettings::getPrefferedFont() { return [UIFont preferredFontForTextStyle:UIFontTextStyleBody].pointSize; }

.h file:

class iOSSettings { public: static int getPrefferedFont(); };

.cpp file:

#ifdef Q_OS_IOS fontScale = new float(getfontScalefrompointSize(iOSSettings::getPrefferedFont())); setup_fontiOS(iOSSettings::getPrefferedFont()); #endif

iOS returns the preffered Fontsize, I implemented a function that returns a factor based on the fontsize because I had to scale the Icons too.
Hope this helps somebody :)

@astoffregen

we included this already

Oh, my bad, I overlooked that. Furthermore, "not installed" points more at deployment being the issue.

What I don't find explicitly in the CMake file, is main.qml.
So I guess it is sort of implicitly added as a resource and main.cppknows how to find it.

=> Is a qmldirdirectory in the resource tree?
Something along the lines of this might help:

install(FILES ${CMAKE_CURRENT_BINARY_DIR}/qmldir DESTINATION "${INSTALL_DIR}"

I just realized that Qt6 is not tested against tvOS specifically and is built against iOS. The latter has wider selection of available frameworks.

I guess I'll need to manually Qt for tvOS.

I must answer my own question. Sometimes I miss the obvious. A Settings.bundle is simply a resource and must be copied to the Resources. Since Apple changed the directory chirarchy in the app bundle, all Resources are files or directories in the root directory. After I realized this, it was simple. Here is a small excerpt of my CMakeLists.txt file:

set(settings_bundle "Settings.bundle") qt_add_executable(tpanel MANUAL_FINALIZATION ${PROJECT_SOURCES} "${settings_bundle}" ) target_sources(tpanel PRIVATE "${settings_bundle}") set_source_files_properties(${settings_bundle} PROPERTIES MACOSX_PACKAGE_LOCATION Resources)

The above code assume, that the Settings.bundle is in the root of the distribution. If this is not the case, then the relative path must be defined as part of the variable settings_bundle.

That's it!

@SGaist did some more tests. removed some lines with errors from .pro and got some more output from qmake2cmake. but only for the easy parts ;-)

android or ios - specific parts are missed.
ATM I'm learning from CMakeLists.txt provided by Qt example apps, other projects and documentation.

what's really missed: official guides for mobile (android and ios) apps (including translations, native code, custom info.plist, Android Manifest, openSSL) from build to deploy and publish to stores using CMake.

of course I'll blog about my findings in some weeks.

Also here is the stacktrace if it helps:

@Paul-Colby if you have any insights, can you please help me with this

@inkfil
At Qt6 all(?) enumerated types have been moved from from a "general, high-level" class/namespace --- like Qt::AlignLeft or QVideoFrame::WriteOnly --- down into a more "specific, low-level" class/namespace --- like Qt::AlignmentFlag::AlignLeft or QVideoFrame::MapMode::WriteOnly. You need to change all your code accordingly. There isn't a definitive list, you just have to find out and do it as necessary.

In https://stackoverflow.com/questions/72086632/migrating-to-qt6-pyqt6-what-are-all-the-deprecated-short-form-names-in-qt5 and/or https://pypi.org/project/PyQtEnumConverter/ somebody wrote some kind of converter for Python/PyQt6 for this, maybe it will give you inspiration to understand what has changed.

@Dmitriano It is probably not a trivial question because, as far as I see, setting window width and height to Screen.width and Screen.height is not a solution, because there can be task bar and something else (I do not know what can it be on iOS) that partially occupies the screen.

Great ! Thank you very much.
