  Firebase Support.
• Once you've read this section and determined that your issue is appropriate for
  this repository, please delete this section.

[REQUIRED] Step 1: Describe your environment

• Xcode version: 12.4
• Firebase SDK version: 8.3.0
• Installation method: [CocoaPods]
• Firebase Component: Analytics

[REQUIRED] Step 2: Describe the problem

App crash

Steps to reproduce:

1. Install 'Firebase/Analytics', '8.3.0', 'BaiduMapKit/Map','6.2.0', 'BaiduMapKit/Utils','6.2.0'
2. Setup firebase
   var options = FirebaseOptions.defaultOptions()
   FirebaseApp.configure(options: options!)

Did you try to run my reproduce project?
I think you can easy to reproduce crash from my project.

This crash could be the result of BaiduMapKit embedding a version of nanopb that is incompatible with the version used by Firebase.

[ngminhduong]

Hi @paulb777
Yes, I found some old ticket with the same issue with BaiduMapKit.
Any solution to fix it from firebase?

Thanks,

[paulb777]

If BaiduMapKit is using nanopb via a CocoaPod without using the nanopb CocoaPod, there's not much we can do on the Firebase side.

They should either use the nanopb CocoaPod with matching preprocessor defines as Firebase or rename all the nanopb public symbols in their internal copy.

[ngminhduong]

Yes, I see. But that difficult to request an update from BaiduMapKit.
They totally not working with GoogleAPI.

[paulb777]

Closing since this seems to be a BaiduMapKit issue and not clear what we can do from Firebase.
