[Python] Executorch v. 0.6 -- Failed build of apple-ios example

I have an issue when trying building the apple-ios example app using XCode. I am working on a MacBook Pro 2021 with M1 processor.

When opening the XCode project I have the following two issues in LLaMaRunner:

Undefined symbol: executorch::extension::llm::load_tokenizer(std::__1::basic_string<char, std::__1::char_traits, std::1::allocator> const&, std::1::unique_ptr<std::1::vector<std::1::basic_string<char, std::__1::char_traits, std::1::allocator>, std::1::allocator<std::__1::basic_string<char, std::__1::char_traits, std::1::allocator>>>, std::1::default_delete<std::1::vector<std::1::basic_string<char, std::__1::char_traits, std::1::allocator>, std::1::allocator<std::__1::basic_string<char, std::__1::char_traits, std::1::allocator>>>>>, std::1:ptional<std::__1::basic_string<char, std::__1::char_traits, std::__1::allocator>>, unsigned long, unsigned long)


Undefined symbol: executorch::extension::llm::create_text_llm_runner(std::__1::basic_string<char, std::__1::char_traits, std::1::allocator> const&, std::1::unique_ptr<tokenizers::Tokenizer, std::__1::default_deletetokenizers::Tokenizer>, std::1:ptional<std::1::basic_string<char, std::__1::char_traits, std::__1::allocator> const>, float)
