no data in firebase crashlytics reports after 1 day

Question

My iOS app is running firebase reports since several weeks. I added crashlytics 2 days ago by following the official steps: https://firebase.google.com/docs/crashlytics/get-started?authuser=0
in fact, It seems all I had to do was to install these pods:

pod 'Fabric', '~> 1.7.2'  
pod 'Crashlytics', '~> 3.9.3'  

I also added "DWARF with dSYM File" for the debug information format on both debug and release build settings

Now when I start the app I can see in the log :

[Crashlytics] Version 3.9.3 (128)

Then I forced a crash from an app launched manually (not with the debugger), and I can see the following in the logs after I restart the app from xcode:
[Crashlytics:Crash:Reports] Packaged report with id '9aeb11f6423b4f11b95a0f3263fc7510' for submission
nothing else regarding crashlytics

my question : Why I can't see any data in the firebase crashlytics reports?

Solution 1

For those who are still having problems. Check if you still have pod 'Firebase/Crash' in your podfile. My problem was fixed when I removed the old Firebase Crash Reporting.

Solution 2

FYI I had a similar experience, except that my errors started showing up within a few hours. Here are the two sets of instructions I followed, the second of which is actually necessary even though it isn't included in "get started":

1. https://firebase.google.com/docs/crashlytics/get-started
2. https://firebase.google.com/docs/crashlytics/force-a-crash

The steps I followed, in case you want to go down the list and make sure you didn't miss anything:

1. Add pods to podfile.
2. pod install.
3. Restart xcode.
4. Add build step.
5. Change build settings to DWARF with dSYM File.
6. Add a button that calls Crashlytics.sharedInstance().crash().
7. Run the app on simulator, stop the app, restart by clicking it, tap the crash button. Restart the app.

8. Instead of Crashlytics.sharedInstance().crash(), call:
   let x: Int? = nil
   let y = 5 + x!

9. Run, stop, click, tap button, crash. Restart.

I'd advise looking at system logs, but it looks like you've already done that. I hope some part of this gives you an idea that helps.

You're using the right pods for Crashlytics in Firebase - you need both the Fabric and Crashlytics pods.

Crashes should appear in the Firebase dashboard with the instructions you went through in https://firebase.google.com/docs/crashlytics/get-started?authuser=0. Make sure you also have Firebase Core in your project by following the "Before you begin" steps.

It's possible that your dSYM is missing, which is needed to symbolicate your crashes. Take a look at https://firebase.google.com/docs/crashlytics/find-missing-dsym?authuser=0 for instructions on how to upload your dSYM and then try out another test crash.

Also, check out my comment in the other answer for clarifications around Crashlytics in Firebase vs Fabric.

Solution 4

Check run script only when installing

Solution 5

I tried the same yesterday, where I crashed the app multiple times. Both with Crashlytics.sharedInstance().crash() and

let x: Int? = nil
let y = 5 + x!

with no results in the dashboard.

Today I tried implement Firebase Crashlytics in another app. But this time I run it on a device instead of in the simulator. And within 5 min. I got data in the dashboard.

So my suggestion is: Try run it on a real device instead of in the simulator.
