I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
Hi @RamjiRajendran, thanks for reaching out. I downloaded the Vuforia Engine SDK from the asset store (here), then used our sample project for Google Analytics on v6000.2.6f2 of the Unity Editor. Though I only imported the Vuforia Engine SDK and did not set up any code for it, I was able to build for iOS with no errors.
Could you confirm if this is the correct one or if I'm missing any additional steps?
Hi @niccolo-hare , I can also take build, but it is not actually building in xcode from the created xcworkspace and throwing error like "Assertion failed: (it != _dylibToOrdinal.end()), function dylibToOrdinal, file OutputFile.cpp, line 5196". Please let me know if need of anything. Cocoapods version 1.16.2
@niccolo-hare POV : in the firebase document, it is mentioned cocoapods version should be downgrade to 1.10.2 here, so I downgrade to 1.10.2 and the xcworkspace file is not generated even though, the cocoapod version is detected by giving ios resolve using external dependency manager. And I tried with cocoapods new version 1.16.2, then the xcworkspace file is generated, unfornately it is not building in the xcode, throwing the error as mentioned above.
Sorry for the wait, @RamjiRajendran. I'm still having some trouble reproducing the behavior you encountered. I'm able to successfully build on Xcode while using Cocoapods version 1.16.2.
I'm thinking this error might be related to the Xcode version you're using, similar to this post from the Unity Discussions forum. For my testing, I was using Xcode version 16.4.
To help us investigate further, could you please confirm which version of Xcode you were using when you encountered this error?
Thanks for confirming @RamjiRajendran. I tried another round of testing with Xcode V26.2 this time, and I was able to reproduce the exact same build failure and error. Though I also tried running a sample project with just the Analytics SDK and no Vuforia, and this seemed to succeed without issues.
I'm thinking this might be leaning more towards an issue with how build settings are handled on Xcode 26 than an issue with the Unity SDK. It's likely due to some old linkers that Xcode uses, but these don't seem to work well with Unity. If so, you could try the solution shared by the user "osmanahsanofficial" on this post and see if it helps resolve the issue. From my testing, the error went away and I was able to successfully build my sample project after applying their solution.
Hope that helps. I'll be closing this issue for now since the error doesn't appear to have been caused by the Unity SDK. But feel free to re-open this issue or file a new one at any time if you have other questions or clarifications.
