Build error. Installing Firebase in Xcode iOS app with multiple targets and NotificationServiceExtensions

Question

I'm trying to integrate Firebase (for Dynamic Links) in my current Xcode iOS project but I have problems with errors in the build (Following this documentation: https://firebase.google.com/docs/dynamic-links/ios/receive).

My Podfile looks like this:

# Uncomment the next line...
# platform :ios, '9.0'


target 'AppName1' do
    # Comment the next line if you don't want to use dynamic frameworks

    use_frameworks!


    # Pods for AppName1
    pod 'Firebase/Analytics'
    pod 'Firebase/DynamicLinks'
end


target 'NotificationServiceExtension' do
    # Comment the next line if you don't want to use dynamic frameworks

    use_frameworks!


    # Pods for NotificationServiceExtension
    pod 'Firebase/Analytics'
    pod 'Firebase/DynamicLinks'end


(... With more targets ...)

TEST1. When I try to complile the App target, this is the errors I am getting:

Error1 Image

'FirebaseCore/FirebaseCore.h' file not found
Firebase.h
While building module 'Firebase' imported from */AppDelegate.h:1.1:
In file included from <module-includes>:1:

Could not build module 'Firebase'
AppDelegate.h
In the file included from */ViewControllerLogin.m:9:
In the file included from */ViewControllerLogin.h:10:

TEST2. If I remove the "pod 'Firebase/ ..." lines from the NotificationServiceExtensions I get these errors:

Error2 Image

'sharedApplication' is unavailable: not available on iOS (App Extension) - Use view controller based solutions where appropriate instead.

'openURL:' is unavailable: not available on iOS (App Extension)

TEST1. If I comment the "use_frameworks!" with #, I get the first errors again.

TEST2. If I comment everything inside the targets NotificationServiceExtensions I get:

Library not found for -lFirebaseCore

For every test I'm doing "pod deintegrate" and "pod install" again, open the PROJECT-NAME.xcworkspace, clean and build.

I don't know what else to try or what I'm doing wrong... (the integration with android was super easy...)

Thanks.

Try this:

target 'AppName1' do
# Comment the next line if you don't want to use dynamic frameworks

use_frameworks!


# Pods for AppName1
pod 'Firebase/Analytics'
pod 'Firebase/DynamicLinks'

target 'NotificationServiceExtension' do
# Comment the next line if you don't want to use dynamic frameworks

use_frameworks!


# Pods for NotificationServiceExtension
pod 'Firebase/Analytics'
pod 'Firebase/DynamicLinks'

  end
end

post_install do |installer|
   installer.pods_project.targets.each do |target|
    puts target.name
 end
end

It didn't work, I get the Error2 from the question. I suspect it has something to do with the Extensions not working well with Firebase (https://stackoverflow.com/questions/50592585/can-firebaseauth-5-0-x-be-used-in-an-ios-app-extension/50607314#50607314) but I don't know what to do. – Marcos May 11 '20 at 14:06
I get the Error2 setting only the targets to NO (require only App-Extension-Safe Api to NO). And if a set everything on the Pod to NO I get a new error: "ld: framework not found Pods_AppName1 clang: error: linker command failed with exit code 1 (use -v to see invocation)". I also tried multiple variations of this with no luck... – Marcos May 11 '20 at 16:54

The problem was related to xcode not building the pods target with the app target.

The correct configuration in the pods file was including the "pod 'Firebase/Analytics' pod 'Firebase/DynamicLinks'" only in the target apps and not in the target Extensions (TEST2 in the question).

After executing "pod update" or "pod install" and opening the correct "your-project.xcworkspace" the answer was to go to Build Settings of the Pods parent Target and set the setting "Build Active Architecture Only" to "No" (Every time a pod is updated, this setting returns to "Yes" in Debug mode). With this, the Pod Target gets build alongside the App Target.

But this time it raised many "Undefined symbols" error. – Eray Alparslan Dec 02 '21 at 21:24 — Eray Alparslan, Dec 02 '21 at 21:24

Firebase Dynamic Links is not currently supported in extensions.

File an issue at https://github.com/firebase/firebase-ios-sdk to request for consideration.
