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

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