Not able to run app in simulator due to framework identifier duplication in Info.plist

[gbejarano01]

Environment

• Xcode version: 11.4
• Firebase SDK version: 6.21.0
• Firebase Component: Auth
• Component version: 6.21.0
• Installation method: Carthage

The problem

Steps to reproduce:

After upgrading to the latest version of Firebase and after adding additional frameworks based on research as in the doc is not clear what to do the app compiles just fine, but when trying to run it I get this:

It seems like the GTMAppAuth.framework and abseil.framework frameworks are both sharing the same app id in the Info.plist

However I'm not sure if it's me doing something wrong or what.

Please see the 2 attachments below that shows the same id:

Thank you!

Are you able to work around this by changing one of the frameworks' bundle identifiers to something else?

By default, neither of those frameworks should have the bundle ID com.firebase.Firebase. Something strange must be going on in the dependency installation process. @paulb777 do you know of anything in CocoaPods that could cause this?

[gbejarano01]

just tried now @morganchen12 but I'm getting another issue, I think unrelated to this. I'll keep you updated. Thanks!

[gbejarano01]

@morganchen12 I modified the bundle ID manually and I fixed the other issue I had (not related to Firebase) and now I'm getting this:

Which is weird, it looks like some lib is not finding the right methods or so...

I'm following this other ticket cause it's addressing the same issue but I can't quite seem to find that helpful as I'm not using cocoapods: https://github.com/firebase/firebase-ios-sdk/issues/4711

[morganchen12]

That method is defined in a category, so you're likely missing the -ObjC linker flag.

[gbejarano01]

Thanks @morganchen12, is this what you mean? It's set correctly and still not working if so:

[paulb777]

The Firebase Carthage frameworks should be linked at build time and not installed at load time.

Make sure this step in the Carthage README is followed:

Please note that you shouldn't add any of the Firebase frameworks to the Carthage build phase (copy-frameworks). The frameworks contain static libraries that are linked at build time.

[gbejarano01]

Thanks @paulb777 I just tried the whole configuration again, and I'm still getting the unrecognized selector issue

Also, remember I had to rename the bundle id so this can work.

Not sure what else to try.

[paulb777]

The most likely cause for both problems is lingering references in the Xcode project. Make sure that there are no Firebase references left before starting the configuration.

[ryanwilson]

Re: bundle IDs, I think #5302 should address it.

[gbejarano01]

Thanks everyone for helping, I deleted everything and re-added all the libraries, now I'm getting another issue related to another info plist when trying to run it, all builds ok

It looks something changed and the Info.plist is not there now:

Old Version

New Version

[paulb777]

It looks like there is still a problem with the Xcode configuration. FirebaseAnalytics.framework should not be added into the bundle - /Users/user/Library/Developer/CoreSimulator/Devices/5D70DC5C-613F-40C2-A963-DE324243E051/data/Library/Caches/com.apple.mobile.installd.staging/temp.KiaLDG/extracted/Payload/project1819.app/Frameworks/FirebaseAnalytics.framework

[gbejarano01]

@paulb777 removed now seeing this when tried running.

[paulb777]

Yep, FirebaseAnalytics still needs to be linked statically. It just shouldn't be added to the bundle. In Carthage, that typically means making sure it is not included in the copy-frameworks build phase.

[gbejarano01]

Yes @paulb777 is not included in the copy-frameworks.

Maybe something that I haven't explained, we went through the initial setup while ago, we were just running Carthage to get the latest framework version, so not sure what could be wrong if we haven't changed anything in the config nor started from scratch

[paulb777]

The only other thing I can think of would be something about Xcode 11.4 is causing it. However, if that were the case, I would expect to see other similar reports.

[gbejarano01]

OK, thanks @paulb777 I'm still getting ld: warning: Could not find or use auto-linked library 'stdc++'

I seem not to find anything about this

[morganchen12]

@gbejarano01 can you share your project?

[gbejarano01]

sorry @morganchen12 I don't think I can, I can send you logs and other things if you want.

[paulb777]

May need to explicitly add libc++ to the Link Binary With Libraries Buiild Phase:

[morganchen12]

Note that you can also accidentally add Carthage artifacts to your bundle if they're in the "Copy Bundle Resources" build phase.

[gbejarano01]

@paulb777

Still getting this

[gbejarano01]

Thanks @morganchen12 there is no Carthage artifact on the Copy Bundle Resources phase

[paulb777]

Ah, the difference between libstdc++ and libc++.

Is there more context around the warning message describing where the reference comes from or what the undefined symbols are?

The warning may be ok with the real issue being the undefined symbols.

[gbejarano01]

@paulb777 That's what I thought, but since I'm not familiar with those libraries, I was unsure.

Please note that now it seems to be referenced from Vision Framework, but before was from a different framework, we had Vision removed, but since you suggested to follow the config from scratch now I added all the Firebase frameworks.

Still we got the same error, before from Analytics: https://github.com/firebase/firebase-ios-sdk/issues/5299#issuecomment-610571991

[paulb777]

@gbejarano01 That error would come from linking FirebaseMLVision.framework without also linking GoogleAPIClientForREST.xcframework. You can find where symbols are defined and undefined with the nm utility like

 $ nm FirebaseMLVision.framework/FirebaseMLVision | grep DetectedBreak_Type_LineBreak
                 U _kGTLRVision_DetectedBreak_Type_LineBreak
                 U _kGTLRVision_DetectedBreak_Type_LineBreak
$ nm GoogleAPIClientForREST.xcframework/ios-armv7_arm64/GoogleAPIClientForREST.framework/GoogleAPIClientForREST  | grep DetectedBreak_Type_LineBreak
-------- S _kGTLRVision_DetectedBreak_Type_LineBreak
-------- S _kGTLRVision_GoogleCloudVisionV1p1beta1TextAnnotationDetectedBreak_Type_LineBreak
-------- S _kGTLRVision_GoogleCloudVisionV1p2beta1TextAnnotationDetectedBreak_Type_LineBreak
-------- S _kGTLRVision_GoogleCloudVisionV1p3beta1TextAnnotationDetectedBreak_Type_LineBreak
-------- S _kGTLRVision_GoogleCloudVisionV1p4beta1TextAnnotationDetectedBreak_Type_LineBreak

[gbejarano01]

OK, @paulb777 I got it working.

I basically created an empty project and followed the configuration again, I had to do some additional things that are not described in the readme but I ended up having it working.

So then, I went into my project, removed all the references to any Firebase framework or dependencies and did exactly what I did with the empty project.

And that made it work.

Only one thing that might help others, after that configuration I got the following that basically was fixed by wiping DerivedData:

If the error displayed above is due to conflicting search paths to Clang modules in different images of the debugged executable, this can slow down debugging of Swift code significantly, since a fresh Swift context has to be created every time a conflict is encountered.` --- It sounds like this is fixed at the moment, thanks so much @paulb777 @morganchen12 for helping me on figuring it out with me. Just a quick feedback if you allow me, I think the setup guide [Carthage README](https://github.com/firebase/firebase-ios-sdk/blob/master/Carthage.md) could include more detail and be more user friendly, specifically about the links to other GitHub issues, it requires some reading and digesting to understand those points. I think also, whatever are the dependencies need to be listed by module/framework somewhere, for instance I had to add libc++.tbd, StoreKit.framework and LocalAuthentication.framework, which for a more advance user is easy to figure out the dependencies (sometimes) by looking at the logs but this would be hard for some other people. In addition and I'm not sure if I did it but it was not needed, I had to add `github "google/promises"` to the Cartfile as well. I think this only applies to Carthage users, it seems like the ones using CocoaPods are not having so much trouble with this. Anyway, thanks so much again for the good work and for helping me on this!

[paulb777]

@gbejarano01 Glad you got it working! Thanks for the feedback about the instructions. We'll consider how to improve them.
