One way to solve the local/global "reaching the logger" question is to provide an "execution context" i.e. implicit parameters. Silently passing extra arguments to all function calls is likely to be prohibitive from a performance standpoint, so an acceptable implementation would likely use something like thread local storage and end up requiring somewhat sophisticated machinery to make sure the "context" is what you expect it to be. Even if implemented, I can see such a feature being abused and decreasing the legibility of Swift code.
That said, Swift already supports some semantics which can also be abused to great effect (like custom operators) and while there are examples of projects doing so, the wider community seems to avoid it.
