如何在默认情况下公开的成员明智的初始化结构在Swift？

我有一个swift框架定义一个结构：

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

但是，我似乎不能使用隐式成员明智的初始化从另一个项目，导入库。错误是’CollectionTO’不能初始化，因为它没有可访问的初始化。即它不给默认隐式成员明智的初始化公共关键字。

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

我必须添加我自己的init方法，如：

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;
    }

}

…但我宁愿不是有另一种方式任何人都知道吗？

我阅读手册：

“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.”
