Duplicate symbol in GoogleMobileVision and GoogleSignin

[ghost]

duplicate symbol _OBJC_IVAR_$_MDMPasscodeCache._localAuthenticationInfo in:
        /Volumes/WD/New Users Home/craigfransen/IntelliJ_Projects/tagger_mob/ios/Pods/GoogleMobileVision/Detector/Frameworks/GoogleMobileVision.framework/GoogleMobileVision(MDMPasscodeCache_f189776e75765630b82721fafea64052.o)
        /Volumes/WD/New Users Home/craigfransen/IntelliJ_Projects/tagger_mob/ios/Pods/GoogleSignIn/Frameworks/GoogleSignIn.framework/GoogleSignIn(MDMPasscodeCache_42de90102bb6814d03833694aafcc99d.o)

I know this is not your issue, but wondering if you know of a workaround

---

UPDATE: one workaround is to

pod 'GoogleSignIn', '4.1.2'

And change the deploment target in XCode to 9.0

Now that that is running, I'm getting black picture in QRCamera frame. Sigh.

Hmmm. Yeah that seems to be a problem that lots of people are seeing who try to use google sign in and google mobile vision. Unfortunate that google hasn't resolved it, although I'd bet that their current answer to that would be to recommend switching to firebase's mlkit as google mobile vision has been more or less deprecated.
