如何修复 CFNetwork 问题 iOS swift？

Question

I have a doubt regarding crashes. In our app, we are getting CFNetwork issues randomly. When we checked the stack trace, we don't have any idea about reproducing. What's the main reason of getting CFNetwork error?

I am using the below third parties:

pod 'Alamofire', '~> 4.7.3'
pod 'Branch'
pod 'Fabric'
pod 'Crashlytics'
pod 'PPpdf417', '~> 5.1.0'
pod 'JGProgressHUD'
pod 'Firebase/Core'
pod 'Firebase/Messaging'

Crash 1:

I can't able to reproduce the crash? Another way to identify this or Give me an idea to fix this kind of errors ?

It happens only on iOS12 And I've found guys using Alamofire/Moya/RxSwift could get this issue

How do you send your request, just Alamofire or Moya?
