React-native-firebase: 🔥 iOS app crashes only release build, in using Dynamic Links.

[cat12079801]

Issue

I tried to use Dynamic Links in React Native Firebase, but in the release build of the iOS app only the app crashes immediately after launching.
I tried on a project that just used React Native Firebase just in case, but unfortunately I reproduced it as well.

Here is the minimal configuration reproduction repository I prepared.

Since I did not get information even after Google search, please tell me what's wrong. Thank you.

#### `ios/Podfile`: - [ ] I'm not using Pods - [x] I'm using Pods and my Podfile looks like:

# Uncomment the next line to define a global platform for your project
platform :ios, '9.0'

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

  # Pods for rnfirebasetest
  pod 'Firebase/Core', '~> 5.20.2'
  pod 'Firebase/DynamicLinks', '~> 5.20.2'

  target 'rnfirebasetestTests' do
    inherit! :search_paths
    # Pods for testing
  end

end

post_install do |installer|
  # This fixes the problems with headers not found
  system("mkdir -p Pods/Headers/Public/FirebaseCore && cp Pods/FirebaseCore/Firebase/Core/Public/* Pods/Headers/Public/FirebaseCore/")
end

The last line is here to help you fix the problem of missing header files at build time. #### `AppDelegate.m`:

You can use Console.app on the mac to watch the logs of a device running the build in release mode if you want, or I think you can run release mode on a simulator as well. There should be a stack trace. You should be careful on your repo posting your google firebase plist/json files as well, hopefully those are on the free plan and semi-disposable...

If you find the stack trace running it under xcode on sim or via console form a usb-connected device paste it in - that will be the fastest thing

[cat12079801]

hi @mikehardy
Oops, GoogleService-Info.plist has deleted its contents. (Fortunately, that account is a free plan.)
And thank you. Later I get the log and paste it here.

[cat12079801]

The stack trace of the application executed on iPhone 8 was acquired in Console.app. A screenshot of the lower part of this app's process and the last two lines of logs.
Please let me know if you have any other information you need.

[mikehardy]

It's crashing in your AppDelegate.m - that's odd. Are you certain you have followed all the other steps (all the apple registration, plist stuff)? Also, I think based only on the sample code https://rnfirebase.io/docs/v5.x.x/links/ios about deeplinks that you need to use react-native linking for deeplinks? I apologize I don't have more experience in the area - I haven't implemented it yet in my app so I'm learning with you.

[cat12079801]

Yes, I did the installation following the steps in React Native Firebase. The app crashes for an unknown reason, so about 3 times from the beginning!

Note: When I checked the Firebase Pod module yesterday, it was v5.20.2.

1. $ react-native init rnfirebasetest
2. https://rnfirebase.io/docs/v5.x.x/installation/initial-setup
   
   
   
   • $ yarn add react-native-firebase
   
   
   • create Firebase project in web console
     
     
     
     
     
     • However, my app has not been published to the store yet.
     
     
     
   
   
3. https://rnfirebase.io/docs/v5.x.x/installation/ios
   
   
   
   • Download and add GoogleService-Info.plist to Xcode project.
   
   
   • Append #import <Firebase.h> and [FIRApp configure]; to AppDelegate.m
   
   
   • $ pod init and edit Podfile, and then $ pod install
   
   
   • open *.xcworkspace
   
   
   • $ react-native link react-native-firebase
   
   

4. https://rnfirebase.io/docs/v5.x.x/links/ios

   • Add pod 'Firebase/DynamicLinks', '~> 5.20.0' to Podfile, and then $ pod update
   • Enter "Associated Domains" in "Capabilities" tab, "Identifier" field in "Info" tab of Xcode.
     
     
     
     • Of course, I am using a certificate with "Associated Domains" enabled.
     
     
   • Add these codes to the appropriate place in AppDelegate.m.

   #import "RNFirebaseLinks.h"
   

   ```
   [FIROptions defaultOptions].deepLinkURLScheme = CUSTOM_URL_SCHEME;

   • (BOOL)application:(UIApplication *)application
     openURL:(NSURL *)url
     options:(NSDictionary *)options {
     return [[RNFirebaseLinks instance] application:application openURL:url options:options];
     }

   • (BOOL)application:(UIApplication *)application
     continueUserActivity:(NSUserActivity *)userActivity
     restorationHandler:(void (^)(NSArray *))restorationHandler {
     return [[RNFirebaseLinks instance] application:application continueUserActivity:userActivity restorationHandler:restorationHandler];
     }
     ```

5. build and run, then app is crash.

Is there anything missing from this procedure? Should I try it with v6.2.0 modules?

[mikehardy]

re: versions, yes I just released v5.5.0 with fully up to date iOS SDK support. It's a breaking change but not a hard one to deal with if you look at the notes. You can try with v6.2.0 but I will be shocked if it alters your results, I don't believe anything much changed in DynamicLinks. I would not change it, though if you do make sure to clean out ios/build after the pod install

you may also need to change the app plist to register the rnfirebasetest URL scheme I think? And in firebase console register it, and in apple entitlements etc etc. Have you tried it with react-native links? there was a code snippet in the docs that tried react-native links first then fell back to firebase?

[cat12079801]

Thank you. I will not try v6.2.0 for the time being.

Sadly, I am not familiar with iOS development and Firebase, and I am not good at English. 😢
Let me ask you questions one by one.

• plist and firebase console

  • Do you mean by these screen shots?
    

    

• apple entitlements

  • What does this mean? Do I need to do anything from the Apple Developer Program website?

• react-native links

  • Does this point to the react-native link react-native-firebase command? Or is it React Native Linking?
    If the latter, I have already tried by typing the URL directly into the safari URL bar.

@cat12079801 , @mikehardy
I am facing the same issue. Our iOS app get crashed in release mode, and works fine in debug mode. So any workaround for this?

[cat12079801]

I'm still facing this problem...
Anyone have a solution?

[vivekshah-zymr]

I'm still facing this problem...
Anyone have a solution?

No, @cat12079801 . I am also facing the same. Having the tread over here.

[cat12079801]

In some cases, commenting out the Podfile use_frameworks! May prevent the app from crashing even in a release build.
I will check back later.

[vivekshah-zymr]

I have other libraries in pod file as well, which requires use_frameworks!. So I can't comment it out.

[vivekshah-zymr]

@cat12079801 ,

I have changed implementation of 2 AppDelegate methods and now I am not having crash.
I changed to the...

- (BOOL)application:(UIApplication *)application
            openURL:(NSURL *)url
            options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options
{
  return [RCTLinkingManager application:application openURL:url options:options];
}

- (BOOL)application:(UIApplication *)application continueUserActivity:(nonnull NSUserActivity *)userActivity
 restorationHandler:(nonnull void (^)(NSArray<id<UIUserActivityRestoring>> * _Nullable))restorationHandler
{
  return [RCTLinkingManager application:application
                   continueUserActivity:userActivity
                     restorationHandler:restorationHandler];
}

Which was before

- (BOOL)application:(UIApplication *)application
            openURL:(NSURL *)url
            options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options
{
  BOOL handled = [[RNFirebaseLinks instance]
                  application:application
                  openURL:url
                  options:options
                  ] || [RCTLinkingManager
                        application:application
                        openURL:url
                        options:options
                        ];

  return handled;
  }

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url
  sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
{
  BOOL handled = [RCTLinkingManager
                  application:application
                  openURL:url
                  sourceApplication:sourceApplication
                  annotation:annotation
                  ];
  return handled;
}

[mikehardy]

Looks like you just removed the react native firebase functionality and are using the react native only functionality? I could see that avoiding a crash but it seems like a temporary solution only unless I misunderstood

Oh, Actually I tried to click on the link and it's opening properly. As it was giving exception on [RNFirebaseLinks instance]: unrecognized selector sent to class 0x1009e1360

@mikehardy , Do you suggest any other alternative?
