My 2c: +1 to reverting private to the Swift 2 meaning and deprecating or using fileprivate as an alias for private.
As a framework developer I am constantly deciding backward and forwards to go private only to realise that my embracing extensions makes it impossible to allow internal properties in private as we don't support stored properties in extensions. And, without it, I think private is overly hamstrung when defining classes and types with extensions. There is no difference to the compilation beyond a rule that the compiler enforces, but can optimise anyway. In which case, it is purely communicative, and is therefore practically useless because I can't declare the property the method uses in that extension anyway. And littering my code with the ugly fileprivate marker is just an annoying inconvenience. +1 also to add in something like 'protected'. It's a hole in the language where subclasses may have reasons to access but other types have no business touching. > On 18 Feb 2017, at 2:38 pm, Jonathan Hull via swift-evolution > <[email protected]> wrote: > > My ideal scenario: > > 1) Go back to Swift 2 meaning of private > > 2) Add the ‘hidden’ axis I talked about in another thread. > > This will provide the capabilities of protected + friend (and allow > extensions organized across files) using a consistent file-based approach > that is easy to reason about.
