Unable to run onnxruntime-genai on iOS (Xcode 15.3)

[ShamDhi]

Hello @microsoftopensource , Hope you're doing well.

I'm unable to run onnxruntime-genai for iOS using Xcode 15.3. I followed the steps mentioned in the demo and this Microsoft link, but the repository you referenced is unavailable (git checkout yguo/ios-build-genai). I proceeded with the main branch from GitHub and set everything up the same, but the application crashes on launch. Even your demo fails to run successfully.

FYI, I also tried the branch (git checkout yguo/chat-app-genai) available on the repo, but in this branch, none of the mentioned commands work, and no code can be executed.

I've attached a screenshot and crash logs from the console for reference. Could you please help with troubleshooting or guide me to resolve this crash? If you need additional details, I’ll be happy to share.

First Crash: /private/var/containers/Bundle/Application/8AC1B341-3A75-4806-AA85-8F61A506F689/OnnxModelFinal.app

Second Crash: libc++abi: terminating due to uncaught exception of type std::runtime_error: Error opening /private/var/containers/Bundle/Application/8AC1B341-3A75-4806-AA85-8F61A506F689/OnnxModelFinal.app/genai_config.json

Thank you!

Hi, the exception indicates that you don't have genai_config.json available. How did you set the model path? Did you copy the required model files?

Yes, @skyline75489, I added all the files correctly and set the path properly. After that, I encountered another error. Please check the screenshot.

Please provide full stacktrace and the exact code you're using if you can. The exception itself is not helpful, if you want others to understand the problem.
