Firebase-ios-sdk: FIRAnalyticsVersionMismatch

[bryan1anderson]

• Xcode version: Version 10.2.1 (10E1001)
• Firebase SDK version:
  Firebase 6.3.0
• Firebase Component
  FirebaseAnalytics (6.0.2)
  FirebaseCore (6.0.3)
  FirebaseInstanceID (4.2.0)
  GoogleAppMeasurement (6.0.2)
  GoogleUtilities (6.2.0)

[REQUIRED] Step 3: Describe the problem

I can't launch my app.

I realize this might be duplicated by #2151 but that issue is closed, and it was for different versions

Terminating app due to uncaught exception 'FIRAnalyticsVersionMismatch', reason: 'Google Analytics for Firebase version (60001000) does not match with Google App Measurement (60002000) version. Please update.'

Steps to reproduce:

I updated pods and now this happens. I was using Fabric but that stopped working today so I moved over to finally use Firebase. Total fail

I found a few problems with this issue:

• I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
• This issue does not seem to follow the issue template. Make sure you provide all the required information.

@bryan1anderson Thank you for sharing your issue. Could you provide a bit more detail on it. I was not able reproduce it locally. Here are the Podfile and Podfile.lock I used.

Could you please do following:

1. Check if a particular version of FirebaseAnalytics or GoogleAppMeasurement is locked in you Podfile.
2. Share your Podfile and Podfile.lock or, ideally, a sample project to reproduce the issue.
3. Share the version of Cocoapods you are using.

Other things to try include an Xcode clean and removal of DerivedData.

[bryan1anderson]

Xcode Clean and removal of derived data didn't do the trick

@maksymmalyhin Here is my podifle.lock

Mysteriously, running off the same branch on a different machine does not cause me this issue. It only began after I updated my pods. I reverted all changes made to an older branch, then ran the older branch off a different machine. Still fails on the original machine though

@bryan1anderson The Podfile.lock content looks correct (consistent version of FirebaseAnalytics and GoogleAppMeasurement). It looks like the Cocoapods repos ended up in an inconsistent state on your machine for some reason.
You may try:

1. If you use a repo CDN, then switch back to the main repo (use source 'https://github.com/CocoaPods/Specs' in your Podfile)
2. remove and re-add your Cocoapods repos.
3. If you commit your Pods folder to your project repo, you can run pod deintegrate then pod update to make sure that the Pods folder content corresponds to the Podfile.lock versions.

@bryan1anderson Definitely sounds like a caching issue. One other thing you may try is to run the following:

rm -fr Pods/ Podfile.lock; pod cache clean --all

Then re-run pod install --repo-update

[bryan1anderson]

@allenktv That did the trick. This can be closed. Was definitely a caching issue. I've never seen this error with a pod before, should have tried that first.
