I use facebook and onesignal. I i remove onesignal i don’t have error, if i compile only onesignal esample, it’s ok, so i don’t understand. It’s my production code i don’t changed anything from my last publish.
qios is the main Qt lib for iOS, this should not be related to the plugin. Can you send the whole build log to firstname.lastname@example.org so we can have a look? Do you maybe also see something else that is suspicious in the build logs?
