<html><head></head><body>I don't think submodules would solve it nicely. Each module/submodule will require it's own namespace + it feels like an overkill to create submodules for a few types. `internal(xyz)` seems to me like a better solution. And yes this is purely additional and nothing for phase 1.<div> <br><div class="bloop_sign"><div style="font-family:helvetica,arial;font-size:13px">-- <br>Adrian Zubarev<br>Sent with Airmail</div></div> <p class="gmail_quote" style="color:#000;">Am 9.

<div>There must be a better solution to this problem, because you
might also extend value types from different files. That would
mean, we'd need `structprivate` `protocolprivate` etc.

<div>How about: `internal(class)` etc. ? Or something like
`internal(private)` to rule them all (I don't like the last name,
but something that would rule them all would be nice to
have)!</div>

<div>I would love to see along side the new fileprivate access
level a classprivate access level that would allow any extension
declared outside of the original .swift file to access these
properties and functions in an attempt to reuse code.</div>
<div><br></div>
an example is below...<br>
<br>
=================<br>
//MyClass.swift<br>
public class MyClass {<br>
<br>
classprivate func sharedFunction() {<br>
self.function1()<br>
self.function2()<br>
}<br>
<br>
fileprivate func function1() {}<br>
fileprivate func function2() {}<br>
}<br>
=================<br>
<br>
<div>=================<br>
<div>//MyClass+Save.swift<br>
extension MyClass {<br>
<br>
public func save() {<br>
self.someFunction()<br>
self.sharedFunction()<br>
}<br>
<br>
fileprivate func someFunction() {}<br>
}
<div>=================<br></div>
<div><br></div>
<div>Currently to achieve anything like this you would have to make
the "core" functions public or internal or write the whole thing in
a single file which as I understand it is not optimal for the
compile speed and can get unmanageable for large classes. This
would allow a more managed file structure and the separation of
related functions from the core declaration.</div>
<div><br></div>
<div>There would be no migration needed I don't think as the impact
on current code would be zero until the developer adopts the new
access level</div>
