React-native-onesignal: Unable to add Notification Service Extension

[yirui94]

Description:

On iOS I am able to setup the SDK to work with notifications, however, after adding the Notification Service Extension I run into an error, notably the symbol(s) not found for architecture x86_64 found in the troubleshooting guide and several other issues opened here.

My main issue is this: I can't add the framework libRCTOneSignal.a because it doesn't exist...? I think I am missing something here? 🤷‍♂️

Environment

OneSignal React-Native SDK 3.2.4

npm install --save react-native-onesignal

react-native link react-native-onesignal

pod version 1.4.0

Expo detached app

Steps to Reproduce Issue:

1. npm install
2. exp detach
3. npm install --save react-native-onesignal
4. react-native link react-native-onesignal
5. cd ios/ and run pod install
6. Configure XCodeProject following the official setup guide
7. At this point if I build and run on my device, I am able to receive the notifications.
8. Following the setup guide to add Notification Service Extension
9. libRCTOneSignal.a cannot be added to the framework since it is not found resulting in the symbol(s) not found for architecture x86_64 build failed error

Anything else:

@yirui94 Thank you for your detailed issue report.

Push notifications will not work on the iOS simulator (this is a restriction from Apple), so please do run on a real iOS device. Do you get the same error regarding arm64?

That said, it would be terrible if OneSignal prevented you from being able to run on simulator (it normally has no issues targeting x86 architecture) so I'll be happy to work with you to fix this issue.

Does this issue _only_ occur for the Notification Service Extension? If you remove the extension, does your main app build successfully?

[yirui94]

Hi @Nightsd01 , indeed I am running on my device. WIthout the Notification Service Extension I can build my main app & receive notifications successfully. But I think you misunderstood me, my main issue is that the framework libRCTOneSignal.a can't be found & thus I can't configure the Notification Service Extension to actually work.

[Nightsd01]

Ah, that's a cocoapods issue then. Essentially, with Cocoapods, you have to explicitly define what dependencies are available for certain targets.

Can you post your Podfile?

Hi @Nightsd01 , it still fails with multiple Undefined symbols for architecture arm64:

I am able to successfully pod install again but I received this warning message:

[!] The `OneSignalNotificationServiceExtension [Debug]` target overrides the `HEADER_SEARCH_PATHS` build setting defined in `Pods/Target Support Files/Pods-Both Targets-OneSignalNotificationServiceExtension/Pods-Both Targets-OneSignalNotificationServiceExtension.debug.xcconfig'. This can lead to problems with the CocoaPods installation
    - Use the `$(inherited)` flag, or
    - Remove the build settings from the target.

[!] The `OneSignalNotificationServiceExtension [Release]` target overrides the `HEADER_SEARCH_PATHS` build setting defined in `Pods/Target Support Files/Pods-Both Targets-OneSignalNotificationServiceExtension/Pods-Both Targets-OneSignalNotificationServiceExtension.release.xcconfig'. This can lead to problems with the CocoaPods installation
    - Use the `$(inherited)` flag, or
    - Remove the build settings from the target.

likely due to setting the header search paths of the extension. Also, the libRCTOneSignal.a framework still could not be found

edit1: Added libOneSignal.a from the SDK directly, but still got this error

ld: library not found for -lOneSignal
clang: error: linker command failed with exit code 1 (use -v to see invocation)

[Nightsd01]

You shouldn't have to manually add libOneSignal, it will be bundled with the react-native-onesignal pod.

The errors you are posting seem to be react-native issues. Are you importing any React frameworks in your Notification Extension Service class/es? Try adding $(inherited) as a header search path in your OneSignalNotificationServiceExtension

Since you are installing with cocoapods, you don't need to worry about adding libRCTOneSignal.a or libOneSignal.a, they will both be bundled in the libPods-xxxx.a framework.

[yirui94]

Adding $(inherited) as a header search path did not help but it did remove the warning messages from pod install.

It seems like I stuck with both approaches. My original podfile gives me this error:

while your updated podfile gives me an entirely different set of errors

[atothewest]

@yirui94 Experiencing the exact same issue myself. Will post an update here if I can figure out a fix today.

[jdegger]

I seem to have fixed something similar by adding a target completely separate from my main target with all the react stuff included. Probably way too much, but I'm not sure what I can leave out at this point.

# Uncomment the next line to define a global platform for your project

@jdegger that approach seems to have worked for me also, nice one 👍

I used abstract_target to tidy up my Podfile slightly:

abstract_target 'MyAppAbstractTarget' do
  pod 'React',
    :path => "../node_modules/react-native",
    :inhibit_warnings => true,
    :subspecs => [
      "Core",
      "ART",
      "RCTActionSheet",
      "RCTAnimation",
      "RCTCameraRoll",
      "RCTGeolocation",
      "RCTImage",
      "RCTNetwork",
      "RCTText",
      "RCTVibration",
      "RCTWebSocket",
      "DevSupport",
      "CxxBridge"
    ]
  pod 'yoga',
    :path => "../node_modules/react-native/ReactCommon/yoga",
    :inhibit_warnings => true
  pod 'DoubleConversion',
    :podspec => "../node_modules/react-native/third-party-podspecs/DoubleConversion.podspec",
    :inhibit_warnings => true
  pod 'Folly',
    :podspec => "../node_modules/react-native/third-party-podspecs/Folly.podspec",
    :inhibit_warnings => true
  pod 'glog',
    :podspec => "../node_modules/react-native/third-party-podspecs/glog.podspec",
    :inhibit_warnings => true


  pod 'react-native-onesignal', :path => '../node_modules/react-native-onesignal'

  post_install { |installer| perform_post_install_tasks(installer) }

  target 'MyOneSignalNotificationsApp' do
    pod 'ExpoKit',
      :git => "http://github.com/expo/expo.git",
      :tag => "ios/2.6.5",
      :subspecs => [
        "Core",
        "CPP",
        "GL"
      ],
    :inhibit_warnings => true
  end

  target 'OneSignalNotificationServiceExtension'
end

I defined perform_post_install_tasks as a separate method to tidy up the target block further, it contains the same auto-generated content as posted in @yirui94's earlier post

I then amended the Build Settings of my OneSignalNotificationServiceExtension target, setting both _Search Paths > Header Search Paths_ and _Search Paths > Library Search Paths_ to $(inherited).

In Build Phases, under _Link Binary With Libraries_, I removed all except:

I then ran pod install, which links the pod libraries to both targets.

At this point, I was able to build successfully and send out notifications 🎉

[Nightsd01]

This is more of a problem with our documentation (for using OneSignal after detaching with Expo) than a bug with our SDK, sorry for the inconvenience this has caused you.

We'll update our documentation to better explain how the SDK should be used in Expo projects (which usually use Cocoapods to manage dependencies as opposed to React's more traditional Xcode sub-project model).

I'll mark this issue as resolved once I've updated our docs, also @yirui94 please let me know if the approach described above by @atothewest resolves the problem for you

[yirui94]

@Nightsd01 @atothewest @jdegger Hallelujah it works! 🎉

Thanks everyone! I'll write up a simple guide on how to get a Detached Expo App + Onesignal working on Android & iOS once I'm done

[hutchy2570]

thanks @jdegger that worked for me too.

[slorber]

Hi,

@Nightsd01 in the meantime could you summarize what the final solution for ejected Expo projects should look like?

I've tried the suggestion of @jdegger , got a lot of warnings

[!] The pod `DoubleConversion` is linked to different targets (["Pods-app-mobile", "Pods-OneSignalNotificationServiceExtension"]), which contain different settings to inhibit warnings. CocoaPods does not currently support different settings and will fall back to your preference set in the root target definition.

And this libPods-...OneSignal.a appeared here:

But I'm still unable to add libRCTOneSignal.a

Is my setup ok or not?

[yirui94]

@slorber as @Nightsd01 mentioned earlier

Since you are installing with cocoapods, you don't need to worry about adding libRCTOneSignal.a or libOneSignal.a, they will both be bundled in the libPods-xxxx.a framework.

warning for the OneSignalNotificationServiceExtension can be removed by adding the $(inherited) under Header Search Paths. The rest are probably due to your cocoapod version

[slorber]

thanks it seems to work fine

Can anyone share a working Podfile? I have tried many different variations but I keep getting build failures:

Edit

It seems we can now just use what the doc says:

target 'OneSignalNotificationServiceExtension' do
  pod 'OneSignal', '>= 2.9.3', '< 3.0'
end

thanks @slorber, I used your Podfile and started all over and now it does build!

[Nightsd01]

Closing issue because it looks resolved by modifying the podfile. If anyone else faces this issue please post and we'll be happy to reopen and help investigate.

Have the same problem when trying to Archive the project in XCode. ((
Though I could add the libRTCOneSignal.a.

I faced the same issue and was not able to build my app anymore. The problem was that I started using Cocoapods in my App and used a similar Podfile as @jdegger here. I just added this at the end of the file:

post_install do |installer|
    installer.pods_project.targets.each do |target|
        if target.name == "React"
            target.remove_from_project
        end
    end
end

The solution was to run react-native unlink react-native-onesignal and then running pod installl again. This worked fine in release mode.

In dev mode I got the same error as @nicubarbaros here. I fixed this with simply adding libReact.a and libRCTWebSocket.a in Build Settings > Link Binary With Libraries.
