Error Message: Upload missing dSYMs to see crashes from 1 versions. Versions affected: 1.0 (1)
I am trying to implement Firebase Crashlytics in my iOS project. I did all the setups according to Firebase Crashlytics Doucmentation. The crash is performed manually when the button is clicked just to see whether the crashlytics is working.
@IBAction func onTestCrashButtonClick(_ sender: UIButton) { Crashlytics.sharedInstance().crash() } But when i tried to see the error report in the firebase console, it shows something like this image.
After reading Get Deobfuscated crash reports I just Set Debug Information Format to DWARF with dSYM File like below but the problem not fixed till now.

If you can find the missing dSYM there, you can upload it again to fix the issue. Sometime, Apple Connect returns some wrong UUIDs, it means the user crashes on a binary has a missing UUID but Firebase Crashlytics received the dSYM of the wrong UUID so they cannot link together and cause the issue.
To manually upload your dSYMs, you can use the console-based "Drag and Drop" option to upload a zip archive containing your dSYM files (go to Firebase console > Crashlytics > dSYMs tab).
Simple Steps Follow 1 Go to archive and right click on the latest version in which you want to get crash report on firebase 2 see the dsyms folder 3 create the Zip file of dsyms folder 4 finally upload that zip file into the firebase console Show activity on this post. The accepted answer is perfect and what I also followed.
When an upload fails, Crashlytics displays a "Missing dSYM" alert in the Firebase console. If you get this alert, first check that Xcode is producing the correct dSYM for every build: Open your project in Xcode and select the project file in the Xcode Navigator.
Google has added a swanky .dSYM upload feature on the Firebase Crashlytics dashboard, no more uploading from the terminal. Edit on March 16, 2020. Google is soon removing the upload feature on the Firebase Dashboard. An uploader script should be used from the terminal to upload dSYMs to Firebase. See Google's instructions here.
Sometime, the dSYM file name is not UUID but binary name. To get the UUID of a certain dSYM file, use this command: dwarfdump -u <dSYM_file> After finding the file, follow this step from Firebase crashlytics to upload it manually. Wait for few minutes to let Firebase crashlytics re-process the crash reports again then the issue would be dismissed.
Only and simple way to upload DSYMS files to Firebase Crashlytics. (April - 2021)
Download appDsyms archive from App Store
1.1 Login: https://appstoreconnect.apple.com
1.2 Go to: MyApps -> Choose your app -> Test Flight -> Select app version that is in the App Store -> Build Metadata -> Includes Symbols (right side) -> Press: Download dSYM.
Open terminal, drag and drop 3 files on terminal on this order:
2.1 drag an drop: "upload-symbols" which can be found in /project/Pods/FirebaseCrashlytics/upload-symbols
2.2 write " -gsp "
2.3 drag an drop: "GoogleService-Info.plist" which can be found in /project/GoogleService-Info.plist
2.4 write " -p ios "
2.5 drag an drop: "appDsyms" folder (unarchived, zip file might not work!) which usually is in Download folder /Users/username/Downloads/appDsyms
2.6 Press Enter
In terminal the complete command should include -gsp and -p ios, full command looks like this: 2.1 -gsp 2.3 -p ios 2.5
/project/Pods/FirebaseCrashlytics/upload-symbols -gsp /project/GoogleService-Info.plist -p ios /Users/username/Downloads/appDsyms All Set, wait for upload in the terminal!
