How to enable Firebase Analytics Debugview on Testflight

Question

I am unable to view analytics debug view after I install the app through TestFlight into my test phone.

I have passed in argument -FIRDebugEnabled, and have tried -FIRAnalyticsDebugEnabled but no luck.

-FIRDebugEnabled -FIRAnalyticsDebugEnabled

If I directly installed the app into my test phone through Xcode, the debug view will be available. But if it's installed through TestFlight, the debug view cannot be seen.

This can be done by injecting special flags into Firebase's local storages. -FIRDebugEnabled command line argument is being checked by both: FirebaseCore and FirebaseAnalytics frameworks. While the former is saving the flag into shared UserDefaults, the latter is using APMUserDefaults private class, which can be accessed in runtime:

if let APMUserDefaults = NSClassFromString("APMUserDefaults") as AnyObject?,
   let userDefaults = APMUserDefaults.perform(#selector(getter: UserDefaults.standard))?.takeUnretainedValue() {
   _ = userDefaults.perform(#selector(NSMutableDictionary.setObject(_:forKey:)),
                            with: true, 
                            with: "/google/measurement/debug_mode")
}
UserDefaults.standard.set(true, forKey: "/google/firebase/debug_mode")

Nice - this works! You can also trigger this at runtime and then kill and relaunch and it'll be the same as launching with the debug flags. – Necromancy

Add the following code before FirebaseApp.configure():

var newArguments = ProcessInfo.processInfo.arguments
newArguments.append("-FIRDebugEnabled")
ProcessInfo.processInfo.setValue(newArguments, forKey: "arguments")

Then, go to your target's build settings and update Release's Optimization level to No Optimization [-Onone].

After that, upload to TestFlight. This method works for me!

Add following code at the first line of application:didFinishLaunchingWithOptions: method of AppDelegate file

CommandLine.arguments.append(contentsOf: ["-FIRDebugEnabled", "-FIRAnalyticsDebugEnabled"])

An addition to the previous answers and for React Native users looking for this, if you are using a library like react-native-config, you can use an env variable to switch this on/off.

Environment variables file example

ANALYTICS_DEBUG=true

In your AppDelegate.mm, inside the didFinishLaunchingWithOptions method:

  NSString *analyticsDebug = [ReactNativeConfig envFor:@"ANALYTICS_DEBUG"];

  if (analyticsDebug != nil && [analyticsDebug isEqualToString:@"true"]) {
    NSProcessInfo *processInfo = [NSProcessInfo processInfo];
    NSArray *arguments = [processInfo arguments];
    NSMutableArray *newArguments = [NSMutableArray arrayWithArray:arguments];

    [newArguments addObject:@"-FIRDebugEnabled"];
    [newArguments addObject:@"-FIRAnalyticsDebugEnabled"];

    [[NSProcessInfo processInfo] setValue:[newArguments copy] forKey:@"arguments"];
  }

  // Setup Firebase
  [FIRApp configure];

Make sure you setup Firebase after, otherwise this won't work.

This fix does not look to work anymore. Do you have a new solution for this ? – Padriac

Not sure if everything is required here, but this works in Swift with the latest versions. In application:didFinishLaunchingWithOptions: and before FirebaseApp.configure():

CommandLine.arguments.append(contentsOf: ["-FIRDebugEnabled", "-FIRAnalyticsDebugEnabled"])
UserDefaults.standard.set(true, forKey: "/google/measurement/debug_mode")
UserDefaults.standard.set(true, forKey: "/google/firebase/debug_mode")

If it does not work for you, in Info.plist, add the key FIREBASE_ANALYTICS_COLLECTION_ENABLED to NO to make sure that the analytics collection will start only after you set the debug mode, and then call after FirebaseApp.configure():

Analytics.setAnalyticsCollectionEnabled(true)

It's ironic that you criticize me for posting a link as a response, while responding with another link. I at least explained what the link contains unlike you :P – Padriac
