Distinguishing between private and fileprivate adds little value; it mainly serves to protect authors from themselves since it's not possible for an outside entity to insert its own code into the compilation unit after it's been compiled*. It's very difficult to see the benefit of having developers auditing individual members' visibilities to such a fine degree.</div><div><br></div><div>(* The same could be said for file-private because of module boundaries, but distinguishing between module-restricted and file-restricted has value for large projects where multiple authors may contribute to the same module quasi-independently. It's also crucial in code-generation cases like protocol buffers where the generator doesn't have control over the module into which the code will be compiled and you still want to be able to use file-private to hide some details of the generated code from clients in the same module.)</div><div><br></div><div> <br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div style="word-wrap:break-word" class="gmail_msg"><ul style="box-sizing:border-box;padding-left:2em;margin-top:0px;margin-bottom:16px;color:rgb(36,41,46);font-family:-apple-system,BlinkMacSystemFont,'Segoe UI',Helvetica,Arial,sans-serif,'Apple Color Emoji','Segoe UI Emoji','Segoe UI Symbol';font-size:16px;background-color:rgb(255,255,255)" class="gmail_msg"><li style="box-sizing:border-box;margin-top:0.25em" class="gmail_msg">Does this proposal fit well with the feel and direction of Swift?</li></ul></div></blockquote><div><div>Yes.
