swift – 如何从具有相同名称的嵌套类型的类中引用全局类型？

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,我有一个错误类型’ThirdPartyAPI.Address’的值没有成员’someProperty’,这意味着编译器引用内部地址而不是全局地址.

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
        }
    }
}
