How can I make the memberwise initialiser public, by default, for structs in Swift?

I have a Swift framework that defines a struct:

public struct CollectionTO {
    var index: Order
    var title: String
    var description: String
}

However, I can't seem to use the implicit memberwise initialiser from another project that imports the library. The error is:

> 'CollectionTO' cannot be initialised because it has no accessible initialisers

i.e. the default synthesized memberwise initialiser is not public.

var collection1 = CollectionTO(index: 1, title: "New Releases", description: "All the new releases")

I'm having to add my own init method like so:

public struct CollectionTO {
    var index: Order
    var title: String
    var description: String

    public init(index: Order, title: String, description: String) {
        self.index = index;
        self.title = title;
        self.description = description;
    }
}

... but is there a way to do this without explicitly defining a public init?

Quoting the manual:

> "Default Memberwise Initializers for Structure Types The default memberwise initializer for a structure type is considered private if any of the structure’s stored properties are private. Otherwise, the initializer has an access level of internal.

> As with the default initializer above, if you want a public structure type to be initializable with a memberwise initializer when used in another module, you must provide a public memberwise initializer yourself as part of the type’s definition."

Excerpt from "The Swift Programming Language", section "Access Control".

While it is not possible to have the default memberwise initializer at least you can make one quickly with the following steps:

UPDATE: Xcode 11 and later

As mentioned by Brock Batsell on the comments, for Xcode 11 and later all you need to is this:

• Right click the class or struct name and choose refactor -> Generate Memberwise Initializer

Xcode 10 and earlier answer

1. Make the object a class temporarily instead of a struct

2. Save

3. Right click the class name and choose refactor -> Generate Memberwise Initializer

4. Change it back to a struct

We now have a ruby gem  to parse a complete swift data model file, line-by-line, and add public access modifiers, public member-wise default initializers, and other things into a separate auto-generated output swift file.

This gem is called swift_republic
