Building Llama IOS Demo failed

[Hanxian97]

Hi I am new to Xcode. I tried to follow this tutorial to run Llama IOS demo on my iPhone.

I went through the process until the "Xcode" section, and opened the project of examples/demo-apps/apple_ios/LLama. When I tried to do "select which ExecuTorch framework should link against which target." I found I cannot link the backends against the main app target, as shown in this figure:

Thus after this, when I ran the app, it failed with the error "PhaseScriptExecution failed with a nonzero exit code".

When I followed the exactly same flow to set up and run this benchmark app, I can successfully run it on my phone.

Do you have any idea on how to properly set up the ExecuTorch dependency for the llama demo app? Thank you so much!

@shoumikhin @Riandy Would you be able to look at this question? Thank you

@Hanxian97 the project you've opened is already set up to work out the box, so just click Run and it should launch the app in Simulator.

@shoumikhin Thank you for your reply. When I click "Run", it will still build before run, and triggered the "PhaseScriptExecution failed with a nonzero exit code" error. Did I miss something?

Or do you have a doc/tutorial for using this benchmark app? I can successfully run this, but I am not sure how to use it/modify it after that. Thank you!

Had the same PhaseScriptExecution error. It turns out Xcode can't find the cmake installed via homebrew that resides in /opt/homebrew/bin/ even if I added it to PATH. So I uninstalled the homebrew cmake and downloaded cmake gui here https://cmake.org/download/ then run: sudo "/Applications/CMake.app/Contents/bin/cmake-gui" --install to install symlinks to /usr/local/bin/ then everything worked fined.
