Use of unresolved identifier 'RCTOneSignalExtensionService'

[gustavomanolo]

Description:
I followed instructions from https://documentation.onesignal.com/v5.0/docs/react-native-sdk-setup and i'm getting the following error in the NotificationService.swift file:

Use of unresolved identifier 'RCTOneSignalExtensionService'

In the following lines:
RCTOneSignalExtensionService.didReceive(self.receivedRequest, with: self.bestAttemptContent);

RCTOneSignalExtensionService.serviceExtensionTimeWillExpireRequest(self.receivedRequest, with: self.bestAttemptContent);

(your description here)

Environment

React native version
react-native-cli: 2.0.1
react-native: 0.55.3

OneSignal React-Native SDK version
3.2.4

How did you add the SDK to your project (eg. npm)
Through npm
npm install --save react-native-onesignal
react-native link

Steps to Reproduce Issue:

• Install the latest react-native-onesignal package

• Replace content from NotificationService.swift (copied from https://documentation.onesignal.com/v5.0/docs/react-native-sdk-setup) with:

`import UserNotifications

class NotificationService: UNNotificationServiceExtension {

var contentHandler: ((UNNotificationContent) -> Void)?
var bestAttemptContent: UNMutableNotificationContent?
var receivedRequest : UNNotificationRequest!;

override func didReceive(_ request: UNNotificationRequest, withContentHandler contentHandler: @escaping (UNNotificationContent) -> Void) {
    self.contentHandler = contentHandler
    bestAttemptContent = (request.content.mutableCopy() as? UNMutableNotificationContent)
    self.receivedRequest = request;
    
    RCTOneSignalExtensionService.didReceive(self.receivedRequest, with: self.bestAttemptContent);
    
    if let bestAttemptContent = bestAttemptContent {
        contentHandler(bestAttemptContent)
    }
}

override func serviceExtensionTimeWillExpire() {
    // Called just before the extension will be terminated by the system.
    // Use this as an opportunity to deliver your "best attempt" at modified content, otherwise the original push payload will be used.
    RCTOneSignalExtensionService.serviceExtensionTimeWillExpireRequest(self.receivedRequest, with: self.bestAttemptContent);
    
    if let contentHandler = contentHandler, let bestAttemptContent =  bestAttemptContent {
        contentHandler(bestAttemptContent)
    }
}

}`

Also when i open the app i'm getting the following error when i try to init OneSignal:

Cannot read property 'initWithAppId' of undefined

@gustavomanolo Are you sure you created the Objective-C bridging header and imported RCTOneSignal into it...?

[Nightsd01]

Closing due to no response...

Hi @Nightsd01 I am facing the same issue.i have created the Objective-C bridging header and imported RCTOneSignal

It looks like this

#ifndef Objective_CBridgingHeader_h
#define Objective_CBridgingHeader_h
#import "RCTOneSignalExtensionService.h"

#endif 

but still i am getting the same error

[yarism]

Having the same issue... tried switching to objective-c to see if that would solve it but only getting

fatal error: 'RCTOneSignalExtensionService.h' file not found

@sksahil030 did you find a solution?

[jephtta]

Any updates on this? Just like @yarism, I have the same issue even though i have created the header file.

[sahil-innostax]

@yarism No, i couldn't find any solution for it

@yarism @sksahil030
I had the same problem. I've solvd it by targeting OneSignalNotificationService, selecting Build Settings, finding 'Objective-C Bridging Header' and adding path to the previously made Objective-C header file. Soemthing like "your project/OneSignalNotificationServiceExtension/Header.h"

[dutterbutter]

I know this issue is closed but I am experiencing the same issue within my NotificationService.swift in the OneSignalNotificationServiceExtension folder. Specifically the Use of unresolved identifier 'RCTOneSignalExtensionService' error.

I proceeded to create a header file within the same folder directory much like @sksahil030

#ifndef OneSignalNotificationServiceExtension_Swift_h
#define OneSignalNotificationServiceExtension_Swift_h
#import "RCTOneSignalExtensionService.h"

#endif /* OneSignalNotificationServiceExtension_Swift_h */

In the OneSignalNotificationService target > Build Settings. I have specified the following Objective-C Bridging Header path, as mentioned by @nord2ost

$(SRCROOT)/../node_modules/react-native-onesignal/ios/OneSignalNotificationServiceExtension/OneSignalNotificationServiceExtension-Swift.h

After running react-native run-ios the error message I am getting indicates it cannot find the NotificationServiceExtension-Swift.h file specified in the Objective-C Bridging Header path. I am sure that is the correct path to file.

Main questions: If creating the Objective-C Bridging Header and adding in #import "RCTOneSignalExtensionService.h" is the solution what is the correct way to implement?

How to resolve Use of unresolved identifier 'RCTOneSignalExtensionService' error.

Thanks.

[dutterbutter]

I must apologize, it was an incorrect path issue. The above steps of creating a header file and then specifying the path in the Objective-C Bridging Header path of the OneSignalNotificationService target was the solution for me. Thanks.

For anyone having issues with this: clarifying @nord2ost

In the OneSignalNotificationService folder > Build Settings > Header Search Paths add $(SRCROOT)/../node_modules/react-native-onesignal/ios

Create a bridge header and name it whatever you want. and add
#import "RCTOneSignalExtensionService.h"
so it looks like

#ifndef YOUR_NAMED_HEADER
#define YOUR_NAMED_HEADER
#import "RCTOneSignalExtensionService.h"
#endif /* YOUR_NAMED_HEADER */

Go back into OneSignalNotificationService, selecting Build Settings, finding 'Objective-C Bridging Header' and add

$(SRCROOT)/OneSignalNotificationServiceExtension/YOUR_NAMED_HEADER.h

Thanks for the clear instructions @vinceprofeta, saved me a ton of time. Some of this stuff isn't immediately obvious for us with limited native iOS dev experience.
