So I recently started setting up app check for my existing Flutter project (for both android and iOS platforms). I've had no problem with android's "Play Integrity", got the necessary debug token, and can successfully send and retrieve data to/from firestore (app check for firestore is currently enforced for my project).
The problem is, I can not get such a debug key for my iOS app. I will list the sources I've used and what I've tried so far.
I have firebase_app_check: ^0.1.1+8 installed via pubspec.yaml
I also added pod 'FirebaseAppCheck' to my Podfile
I have the necessary initialization code in my main.dart: await FirebaseAppCheck.instance.activate(...);
For "DeviceCheck", I am using THE SAME private key that I am using
for "Sign in With Apple" (which I have implemented successfully). I
have also enabled the checkbox for DeviceCheck in the settings of
that private key (in Apple Developer).
For my App ID (Apple Developer > Identifiers > App IDs), I have also
enabled the checkbox for "App Attest".
I have put "-FIRDebugEnabled" as an argument passed on launch in
XCode > Product > Scheme > Edit Scheme.
I always uninstall my app from my iOS simulator (iOS 16.2) or real device (iOS 16.1.2),
before trying again, because I have read across multiple forums that
the debug token only gets printed to the output the first time you
run your app.
I have also added these 4 lines of code in my AppDelegate.swift from here:
#if DEBUG
let providerFactory = AppCheckDebugProviderFactory()
AppCheck.setAppCheckProviderFactory(providerFactory)
#endif
Official firebase docs "iOS+ (App Attest)":
I have NOT copied ANY code from this page of the official docs, as I assume it's for native iOS apps only, and not for flutter, and I don't know where exactly I would have to put that code. I have only added the pod dependency and run pod install.
I don't have a .entitlements file.
So after all those steps, I'm apparently supposed to expect to find a debug token in my run output, as in:
Yet the only relevant output I can find is the following:
Runner[72719:33546579] 10.3.0 - [FirebaseFirestore][I-FST000001] AppCheck failed: 'The operation couldn’t be completed. (com.apple.devicecheck.error error 1.)'
If it matters:
I have NOT YET uploaded my iOS app to apple developer, app store connect or whatever (I'm not yet familiar with the process of publishing to the app store).
Neither have I uploaded my android app to Google Play console or created an app there (for this project).
Don't tell me anything about firestore rules. I already had that set up long ago, and everything worked just fine before I started integrating App Check.
Don't recommend any 3rd party plugins to me, I will only use official ones.
The firebase documentation says:
Tip: Confirm in your Xcode project's build settings that it passes the DEBUG flag to the Swift compiler
Try removing the '#if DEBUG' and '#endif' and run the app.
If it works, it mean you have missed that step
I was not able to find that build setting, so i just removed those lines from the AppDelegate, but i need to keep in mind to remove the other 2 lines while building the release mode
See this answer on the flutterfire Github issues page. Basically, call setAppCheckProviderFactory before GeneratedPluginRegistrant.register(with: self) in the app delegate file. I was investigating the same issue and it fixed it for me (the debug token was instantly printed out in Xcode's debug output). Hope it helps you as well!
I just implemented Fabric Crashlytics tool to my Xcode project via Swift Package Dependencies.
All works good if I enable Google Analytic on a step when I create an app, without this step I did not received crash reports, so I switched to the app with Google Analytic enabled.
I've tested crash button from the link:
One comment that I don't like from there
"After your app crashes, run it again from Xcode so that your app can
send the crash report to Firebase."
Does it mean that user has to reopen app to send crash report? For example if a user download an app from the App Store and then somehow the app is crashed. Does mean that reopening app required for sending that crash? And if the user will not open the app it means I lost this crash report? I understand that on live store there is no option to re run it form Xcode, but reopening seems a require step.
I suppose the crash report should work different a bit by sending issue details right after a crash, I may be wrong here.
Also when I set everything via Swift Package Dependencies looks like I don't have an option to upload dSYM via this option
/path/to/pods/directory/FirebaseCrashlytics/upload-symbols -gsp /path/to/GoogleService-Info.plist -p ios /path/to/dSYMs
Does this mean I need to pull Fabric and Crashlytics from CocoaPods?
I've switched off bitcode at the moment and looks like all is works automatically but not sure it is good idea for long perspective.
Yes, crashes will be uploaded when restarting the app after it crashes. As far as I know, this is because the SDK may not have enough time to actually send the report when the crash happens.
If you are using Swift Package Manager, you still have that option.
This is the command:
"${BUILD_DIR%/Build/*}/SourcePackages/checkouts/firebase-ios-sdk/Crashlytics/run"
If the app has bitcode enabled, then you'll need to download the dSYMs from the App Store and upload them manually.
Lastly, Fabric is now deprecated so don't download it. You don't need to use Cocoapods if you are already integrated Crashlytics with SPM.
I have run my app on a device and in simulator with no success of updating the Firebase Crashlytics system.
I am not getting any errors, and I know that it's installed because it says the version number (4.5.0) in console.
Also Firebase Analytics is working.
I have followed the install guide to a T and also tried to force crash it by creating a SwiftUI button and using
fatalError()
Which seems to not fully crash the app, but more freeze the app.
I am wondering how I can trace this issue with SwiftUI and Firebase.
In addition of doing what the accepted answer recommends and I believe this is something new from Xcode 12.+. You need to uncheck the two checkboxes below the script window (at least once - you may tick them back up once registered with firebase). This (as stated) forces the script to run and therefore to communicate with firebase... the checkboxes unticked
As outlined here, if you're going to use the Xcode Simulator, you must detach the Xcode debugger at runtime by launching the app directly from the Simulator and not Xcode. Xcode automatically attaches its debugger if you launch from Xcode to a Simulator, blocking Crashlytics from being able to see exceptions/crashes.
I am using CoreData and experiencing the following:
I install my app through the App Store. That build was built with the iOS 6 SDK.
I run the app, and it stores something with CoreData.
Then I upgrade the app through TestFlight (a new build done with the iOS 7 SDK) and the behaviour is not the expected one, seems that a NSManagedObject field is returning nil (I know it shouldn't make any difference, but I am accessing to it with valueForKey:).
Wanting to know what's going on, I uninstall the app, install it again from the App Store and run the version submitted to TestFlight from Xcode to debug it. I see that that valueForKey: is returning nil the first time I run the app, but the second time I follow the same steps(uninstalling and install from the App Store and then run with Xcode) the problem is gone. From this moment, if I follow the original steps(AppStore -> TestFlight) it always works as it should, that valueForKey: call is not returning nil anymore. Weird.
So, say that this is fixed on my device, but a team mate who never run the app with Xcode is experiencing the mentioned problem.
I have tried to set the persistent store options like commented in this answer (submitting it to TestFlight), but it didn't help - my team mate is still experiencing the problem.
Have anyone had a similar issue before? Any idea about the cause of this problem?
Without running the application in Xcode, against a debug build you are not going to be able to debug this issue without a LOT of effort.
Whoever is developing the application should be running it in debug mode and can watch the console, set breakpoints, etc. to solve the issue.
I've setup the Crashlytics in my one iOS application and installed the application on a real device. My Crashlytics Dashboard is displaying that, I've successfully added the app. However, it's not sending crash report. My internet speed is not so good. But I can check my emails from this device. Can anybody guess, where is the problem?
Xcode debugger does NOT allow Crashlytics to process crash reports. Yeah, that seem weird even to me when I read that first time but it is a fact (Source). That's is the reason we never see crash report When:
- running app in Simulator
- running app on iDevice by directly build and run from Xcode with debugger on.
To make sure a crash is reported during your testing (copied from Crashlytics support site):
1. Launch simulator
2. Press stop
3. Launch your app and force a crash
4. Relaunch the app from simulator
5. See the crash report in the web dashboard.
EDIT:
Added a reference; Crashlytics also provides a short article on a quick way to force a crash.
My be it's late but work 100%
Make some changes in project build settings like in below image
and follow these instructions.
The primary reason any crash reporter won't work on iOS is due to interference from different crash reporters. However, with Crashlytics specifically there could be something specific to them causing the crash report not getting reported.
Xcode debugger does NOT allow Any Crash Reporter to process crash reports. This is because XCode overrides any hooks into the crash handling call backs. This only happens when:
running app in Simulator (with debugger on)
running app on iDevice by directly build and run from Xcode with debugger on.
To make sure a crash is reported during your testing (http://support.crashlytics.com/knowledgebase/articles/92523-why-can-t-i-have-xcode-connected-):
Launch simulator
Press stop
Launch your app and force a crash
Relaunch the app from simulator
See the crash report in the web dashboard.
While a super old video it's still relevant, here's a video of the steps above (example from Crittercism): https://www.youtube.com/watch?v=sU6Su3PBFH4
For me, the problem was that the device was connected to my Mac :)
From this source:
Also, if you have your device connected to your Mac, XCode's debugger
will step in as well. So just disconnect the device before testing :)
I found solution using following steps
1. Go to Edit Scheme
2. Run -> Info
3. Change Build Configuration to release.
Now run the app crash it. You will receive mail.
We recently ran into this issue and I found that somewhere along the way the build script was removed. Adding it back in with the following fixed the issue for us:
./Crashlytics.framework/run <your_api_key> <build_secret>
Note : When using Cocoapods you will want to us the following instead of the above (source):
./Pods/CrashlyticsFramework/Crashlytics.framework/run
Adding a build script:
To add a Run Script Build Phase in Xcode 6, select your application target in your project, then select "Build Phases".
Click the small "plus" icon and select "New Run Script Build Phase".
You should now see a Run Script section in the middle of your Build Phase options, as shown above.
Inside the body of the Run Script Build Phase, paste in the script.`
The above quote comes from Crashlytics's visual tutorial, referenced in this post.
Note: I originally posted this answer verbatim for Crashlytics error code: 202 when Submitting files.
From the RayWenderlich site:
You won’t get any crash reports if Xcode intercepts the crash event!
To make all the examples below work, you have to build and run the
application, then click the stop button on Xcode. This way you will
have the latest version installed on the the device. Once that is
done, you can launch the app on the device itself, and then crash it
all you want! All the crashes on your iOS device will be caught and
sent to the server component of the service that you have integrated
into the app. Crash reports are usually sent to the server the next
time you start the app, so the steps to follow to generate a crash
report on the server are as follows: Build and run on Xcode. Press the
stop button. Run the app on your iOS device. Make the app crash. Run
the app again.
Crashlytics works for me until now.
I don't know why but now it doesn't work.
You should turn debug-mode on by
[Crashlytics sharedInstance].debugMode = YES;
My problem is here Crashlytics error code: 202 when Submitting files :(
Make sure you are not forcing the crash too early.
Set [Crashlytics sharedInstance].debugMode to YES;
Watch for
Crashlytics] Settings loaded
on the Xcode console logs.
Then force the crash and restart the app, and the crash will be reported now.
I ran into a similar problem when trying the test crash code.
Crashlytics.sharedInstance().crash()
I was running my app from a device, without Xcode, and the crash wouldn't show up on Crashlytics Dashboard. What worked for me was the following tip from Crashlytics website:
Make sure to launch the app after crashing it, so that the crash can
be uploaded
I commented out the above crash() call, and re-ran the app. Then the crash showed up in the Dashboard.
This is for xcode 9, from crashlytics 3.4.0
After doing this, be patient and wait for a few minutes.
Have you tried running [[Crashlytics sharedInstance] crash] on a device and seeing if that gets reported? There are a few reasons why Crashlytics might not work including other crash reporters etc.
If you don't upload the dSYM file, Crashlytics will not show your crash even though the report successfully uploaded.
You could run into this problem, if you have set up your build-script to only run on your CI server. Then if you have copied your app to your phone via xcode and you run it without being attached to the debugger, the report will be uploaded but ignored, because of the missing dSYM file.
Sometimes, it takes some time for the logs to show up. I am able to find them after 15-20 mins
One of the issue I feel that in the Run Script Phase, it should be a separate Run Script Phase for CrashLytics. When had the run script
./Fabric.framework/run
With some of my other script, everything was ok, CrashLytics log show report submitted, but nothing was in the web interface.
When I add another Run script phase only with Fabric run, it appears like a magic :)
My first try was with cocoapods, but that did not work.
When I manually add all the framework and a separate run script phase that worked.
This worked for me,
If you're testing on iDevice, just unplug iDevice with your Xcode and run your app.
Now, If crashed it will be updated on dashboard.
I solved by deselecting "Run Script only when installing" option in Run script (one for Fabric(crashlytics))
