Hi @pendora7
Try this:
pod repo update
After uninstall and install OneSignal again
ionic cordova plugin rm onesignal-cordova-plugin
ionic cordova plugin add onesignal-cordova-plugin
I am using cordova-ios 5.0.0 to XCode 10.x
ionic cordova platform rm ios
ionic cordova platform add ios@5.0.0
It works for me
Greetings
