How can i fix it? I tried to reinstall xCode 12 and problem still occurs. Any ideas?
Thanks in advance, Paul

@Pientashek Did you try a more recent Qt version?

@jsulm no, i didnt because i had problems with QMQTT module compilation for iOS/Android (for me only 5.12.9 version works).

[Pientashek]

For Qt 5.15.1 version this step is passed but there is another issue: https://forum.qt.io/topic/119708/qtmqtt-build-for-ios-error

For those who got here in desperate search of answer...

qt_import_plugins(${PROJECT_NAME} EXCLUDE_BY_TYPE platforms)

this disables linking of the platform plugin in Qt6::Gui, therefore solving the error.
Because most probably you link the module in order to work with colours or something like this.
The qt_import_plugins can be even more refined. If you are interested, just google it.
