Missing GULSwizzler.h file

Question

I've upgraded an iOS/Swift project to the latest Firebase pods. The following changes were made:

• Firebase 5.11.0 (was 5.10.0)
• FirebaseAnalytics 5.3.0 (was 5.2.0)
• FirebaseCore 5.1.6 (was 5.1.5)
• FirebaseInstanceID 3.3.0 (was 3.2.2)
• GoogleAppMeasurement 5.3.0 (was 5.2.0)
• GoogleUtilities 5.3.4 (was 5.3.3)
• nanopb 0.3.901 (was 0.3.8)

I'm getting an error on a missing file that's imported in GoogleUtilities at build time:

'Private/GULSwizzler.h' file not found

My pod import file has the following:

pod 'Firebase/Core'
pod 'Firebase/Storage'
pod 'Firebase/Database'
pod 'Firebase/Auth'
pod 'Firebase/AdMob'
pod 'GoogleSymbolUtilities'
pod 'GoogleInterchangeUtilities'

Has anyone come across this or know a solution?

******************************** edit ********************************** What I see under GoogleUtilities is shown below. I note that the .h symbol is dimmed for the file that's missing.

It seems that GULSwizzler.h is not installed properly. For me, it is installed in a different location:

 $ find . | grep GULSwizzler.h
./Pods/GoogleUtilities/GoogleUtilities/MethodSwizzler/Private/GULSwizzler.h

Here are a few things to try:

• Reinstall from a clean environment: pod deintegrate and pod install

• Make sure you have the latest version of CocoaPods:

  $ pod --version 1.5.3

Probably unrelated, but strange: GoogleSymbolUtilities and GoogleInterchangeUtilities are deprecated private pods that were never intended to be added to Podfiles.
