I refer to Swift as a "compiled language" because no officially provided interpreter exists for it.

Bitrig runs Swift apps which are dynamically generated by an LLM on the iPhone, despite the iPhone strict security provisions (e.g. inability to write executable pages of memory). The way we do this is by parsing the generated Swift code and mapping that to the compiled calls to the libraries that come in the OS. It's pretty weird, but we think it's worth it to get the ability to immediately render the generated code on the phone.
