Debug build works well.
I'm using Kits without any changes

will open a Bug.
Do you know if this is a Qt Bug or a Qt Creator Bug ?

has someone an idea HowTo get rid of these warnings ?

thx

@ekkescorner found a way to disable this from Xcode Build Settings

unfortunately a new build from Creator resets the value

with a little help from @Jake-Petroules:

here's HowTo avoid all these warnings.
Add into .pro

iOS {
    ...
    disable_warning.name = GCC_WARN_64_TO_32_BIT_CONVERSION
    disable_warning.value = No
    QMAKE_MAC_XCODE_SETTINGS += disable_warning
