Firebaseui-ios: gRPC warnings in FirebaseUI/Firestore

[morganchen12]

gRPC and its subdependencies bring in several new warnings (Pointer not aligned, Control may reach end of non-void function). This is something they are aware of, and will likely fix within the next few weeks.

The latter warning may be promoted to an error by newer versions of CocoaPods/Xcodeproj. If you're running into this, you can fix it by running pod update and ensuring your gRPC-Core pod version is 1.6.5 or higher.

@morganchen12

Installing gRPC (1.6.5)
Installing gRPC-Core (1.6.5)
Installing gRPC-ProtoRPC (1.6.5)
Installing gRPC-RxLibrary (1.6.5)

And I'm getting these 24 errors:

@unittesting0 can you expand those errors and paste them here or share a project that reproduces the issue? What CocoaPods and Xcode versions are you using?

@morganchen12 I know this is closed, but I am having the same issue (pointer not aligned). But the problem is I am not using Cocoapods, I manually linked everything using the guide here https://firebase.google.com/docs/ios/setup. "Integrate without CocoaPods"

I am on Xcode 9.0.1, with a target of iOS 11.

So are the linked frameworks out of date? https://firebase.google.com/download/ios Firebase 4.4?

@elmateo487 yours is a different issue than this one, and lies in upstream Firestore. I'm not sure what the timeline is for resolving it. Those warnings are harmless (though annoying), and you should be able to ignore them for now.

I tried in a new project, same issue.
Used Xcode 8.3.3 , 9.0, 9.1 - same issue.
pod repo update - same issue

How can I resolve this issue.

What's the contents of your Podfile.lock?
