在swift4中使用JSONDecodable时出错？

Question

我在swift4中使用JSONDecodable时遇到以下错误。 "Type UserRegister does not confirm to protocol 'Decodable' "

我的模型结构看起来像这样。

struct UserRegister: Decodable {
    let id : NSInteger
    let name : String?
    let email : String?
    let cities : Array<Any>?
    let tax : [tax]
    let username : [username]
}

struct tax : Decodable {
    let deviceId : NSInteger?
    let financialYear : String?
    let country : String?
    let name : String?
    let state : String?
    let taxCode : String?
    let value : NSInteger? 
}

struct username : Decodable {
    let email : String?
    let phone : String?
}

问题是Array<Any>。您需要一些Decodable类型的数组，例如String或Int。
