Same here I’m encountering a runtime issue after upgrading to Xcode 16. I’ve updated and reinstalled all necessary dependencies, including Cocoapods, but the issue persists. It seems that the current version of the OneSignal pod is not compatible with Xcode 16 or the iOS 17 SDK.

Cocoapods and other dependencies are up to date, but there appears to be no compatible pod available for OneSignal with Xcode 16.

I’ve notified OneSignal support, but there doesn’t seem to be an urgent fix planned at the moment.

Environment:

•	Xcode version: 16
•	iOS SDK: 17
•	Cocoapods version: 1.15
•	OneSignal pod version: ^5.1.2

Steps to Reproduce:

1.	Update to Xcode 16 and iOS 17 SDK.
2.	Integrate the OneSignal pod into the project.
3.	Run the app, and observe the runtime issues.

Notified OneSignal directly as I can’t release a new build with OneSignal installed.

I solved the error by doing this:

Remove this in the OneSignalNotificationService target:

And add these:
