如何从具有相同名称的嵌套类型的类中引用全局类型? [英] How to refer to a global type from within a class that has a nested type with the same name?

问题描述

我有一个在全局范围内声明的类，另一个嵌套在某个类中的同名类.

I have a class declared at the global scope and another class with the same name that is nested within some class.

class Address {
    var someProperty: String?
}

class ThirdPartyAPI {
    class Address {
        var someOtherProperty: String?
        init(fromAddress address: Address) {
            self.someOtherProperty = address.someProperty
        }
    }
}

问题是:如何从初始化程序中引用全局类而不是内部类?在给出的示例中，我出现了错误Value of type 'ThirdPartyAPI.Address' has no member 'someProperty'，这意味着编译器引用内部的Address而不是全局的.

The question is: how can I refer to a global class instead of the inner one from its initialiser? In the example given I've got an error Value of type 'ThirdPartyAPI.Address' has no member 'someProperty', which means that compiler refers to the inner Address instead of a global one.

推荐答案

使用typealias

class Address {
    var someProperty: String?
}

typealias GlobalAddress = Address

class ThirdPartyAPI {
    class Address {
        var someOtherProperty: String?
        init(fromAddress address: GlobalAddress) {
            self.someOtherProperty = address.someProperty
        }
    }
}
