如何从具有相同名称的嵌套类型的类中引用全局类型？

Question

我有一个在全局范围内声明的类,另一个具有相同名称的类嵌套在某个类中.

class Address {
    var someProperty: String?
}

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

问题是:如何从初始化中引用全局类而不是内部类？在给出的示例中,我遇到了错误Value of type 'ThirdPartyAPI.Address' has no member 'someProperty',这意味着编译器引用内部Address而不是全局内部.

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
        }
    }
}
