1) Move the low-level runtime code into swift/runtime 2) Move the high-level "standard library" code into swift/stdlib The key difference is that the 'runtime' contains language support logic (like retain/release logic) that the compiler assumes to always exist and may assume intimate details about the implementation. This library will have intimate knowledge of the swift ABI. In contrast, the 'stdlib' can be completely rewritten and the language/compiler make little if any assumptions about it. It is expected to reexport fundamental types and operators, and implement fundamental policies (precedence, implicit conversions, etc). Swift SVN r3045
