class members are private by default

Question

Isn't there a way to make every member of a class be private or fileprivate by default?

I would rather have everything private by default, and just mark the funcs and vars that I want other parts of my program to see.

Much the way objectiveC did actually. Where I would only put the public stuff on the header file.

I realize not everybody would like this, so I suppose swift lets us choose our way.

So is there a way to let the programmer specify the rule that he prefers at the beggining of every file like:

@default_to_private or @private_members or @private_by_default or something?

Or maybe there is a build setting for that, that changes the behaviour on all files of the project.

Please let me know.

Answer 1

What I usually do is put my public API in the class and my private API in extension:

public class Blob {
    public init(sqishiness: Int) {
        self.sqishiness = sqishiness
    }
    public let sqishiness: Int
}

private extension Blob {
    func simulatorFluidDynamics() {
    }
}

Note I have to explicitly flag

init(sqishiness:)

and

sqishiness

as

public

because they default to

internal

.

The only gotcha with this appropriate is that store properties have to be declared within the class, so you have to explicitly flag those as

private

.

Ok.

That seems like a good work arround.

Thanks.

But I dont consider it a solution.

I'll probably file a radar on the bug reporter then.
