Answer 1

In my case this issue occurred when I switched from PushNotificationIOS provided with the React Native core to the extracted version from @react-native-community/push-notification-ios. (Around version RN 0.60)

After linking the new library and installing the CocoaPods dependencies of the iOS project this issue started popping up.

For some reason while setting up the core RN Push Notification library I manually added libRCTPushNotification.a to the "Linked Frameworks and Libraries" of my project. Removing this reference to the core library resolved the issue and let me compile again.

Answer 2

The PushNotificationIOS was split out from the core React Native. So this issue comes up when migrating to the new module @react-native-community/push-notification-ios.

To fix this, just remove or comment out the PushNotificationIOS library from the Podfile: ./ios/Podfile pod 'React-RCTPushNotification', :path => '../node_modules/react- native/Libraries/PushNotificationIOS'

Then, run the following commands: rm -rf Pods pod install

Rebuild and then run your project.
