<div class="">As Jordan mentioned, I don't (and I think other
people don't) think of extensions as their own entities, as they
can't be referred to and have no runtime representation. In that
mental model, there isn't such a thing as "an extension being
public." Instead, the access modifier is just a shorthand default
for the properties and methods it contains, which is teachable but
unique to extensions. It is a matter of opinion whether that
uniqueness is a feature or a bug.<br class=""></div>

I would say that it's interesting but ultimately not worth the
confusion about the nature of extensions.</div>

<div class="">-1. Extensions appear to me to follow the access
control of the rest of Swift: Implicit to the type you are
extending, and you can either / both declare as part of the
extension declaration or on the method. I don’t see how this is
confusing, and I expect people will be more confused that
extensions don’t follow the convention of the rest of Swift for
Access Control.</div>

<div class=""><br class=""></div>
<div class="">So, actually, the proposal is correct that extensions
(at least once fileprivate/private is implemented) don't follow the
access control rules for the rest of Swift. There is a problem to
be addressed. However, I agree that this proposal hasn't identified
the issue or adequately explained how the solution solves it.
Here's the problem I'm thinking of:</div>
<div class=""><br class=""></div>
<div class="">```</div>
<div class="">public struct foo {</div>
<div class=""> func frobnicate() { } // implicitly
internal</div>
<div class="">}</div>
<div class=""><br class=""></div>
<div class="">public struct bar { }</div>
<div class="">public extension bar {</div>
<div class=""> func frobnicate() { } // implicitly
public</div>
<div class=""> // at least, according to the revised rules
explained in SE-0025</div>
<div class="">}</div>
<div class="">```</div>
</div>
</div>

<div class="">There is definitely a difference, I think that is a
good thing. <span style="background-color:rgba(255,255,255,0)" class="">They look similar but they are completely
different. </span></div>
<div class=""><br class=""></div>
<div class="">public Type // the type is public</div>
<div class="">public extension Type // the extension is
public </div>
<div class=""><br class=""></div>
<div class="">For extensions, public is just a modifier on
extension, not the type. The default scope inside the extension is
that of the "modifier" keyword on the extension. </div>
