I'm following this guide on adding OneSignal to React Native, and there is one section where is says:
Open NotificationService.m or NotificationService.swift and replace the whole file contents with the code below:
<provides code to add>
If you are using Swift, make sure to create a separate Objective-C Bridging Header for your OneSignalNotificationExtensionService and add the following import:
#import "RCTOneSignalExtensionService.h"Then you need to tell your Xcode project settings what your bridging header is named, like this.
I added the code they provided to NotificationService.swift because that's the only one of the two files that exists in my project. So I assume I'm "using swift" as they put it. The problem is that when they say to create a separate Objective-C Bridging Header, I don't know how to do that. All I've been able to find online is that when you import Objective-C code into your swift project, Xcode should automatically prompt you to create a bridging header. Xcode hasn't done that for me.
Does anyone know how I can create an Objective-C bridging header?
