Description
To reproduce this, create a new Qt Quick project with Creator's wizard, add a QtQuick.Controls import and run it on an iOS emulator.
Qt Quick Controls does exist on the host:
mitch@Mitchs-MacBook-Pro ios % pwd /Users/mitch/dev/Qt/6.8.1/ios mitch@Mitchs-MacBook-Pro ios % ls qml/QtQuick/Controls Basic libqtquickcontrols2plugin.a FluentWinUI3 libqtquickcontrols2plugin.prl Fusion libqtquickcontrols2plugin_debug.a Imagine libqtquickcontrols2plugin_debug.prl Material objects-Debug Universal objects-Release designer plugins.qmltypes iOS qmldir impl
With QML_IMPORT_TRACE=1:
09:56:11: Starting remote process.
QML debugging is enabled. Only use this in a safe environment.

The problem is that this code is missing from the CMakeLists.txt:
find_package(Qt6 REQUIRED COMPONENTS Quick QuickControls2)
...

)
New users that are just using the project that Creator makes for them won't know this, so we should think of a way to improve this experience for them.
