Upload iOS symbols to Fabric/Crashlyrics

Hello,
it looks like that our iOS symbol files get not uploaded to Fabric/Crashlytics in the build process. The SDK uses a Xcode shell script execution build step to run a binary for the upload. In the logs, we can see that the script gets executed and there are no errors. On a local machine, everything works out of the box.
Does anyone have similar problems or have a solution?

Best

Does that shell script rely on some local configuration that might be missing in UCB (i.e. credentials, API keys, etc.)?

Hey, it should have everything it will need in the package.
If you want to test is have a look here: Firebase | Google's Mobile and Web App Development Platform

Did you have any luck getting Fabric crash symbols to upload with UCB? We’re currently looking at the same thing, which we’d rather not do, but Unity Performance Reporting doesn’t seem to be working for us, so looking at other options.
