Structify将 Swift 结构转换为 Objc 类的工具-技术圈

Structify 旨在让你更轻松将 Swift 结构转换为 Objective-C 类，开发者无需手动将结构转换为类，反之亦然。

不使用 Structify

struct User {

    let address: String

    let company: String

    let email: String

    let name: String

    let phone: String

    let uid: String

    let username: String

    let website: String

    let birthday: Date

}



class RLMUser: Object {



    @objc dynamic var address: String = ""

    @objc dynamic var company: String = ""

    @objc dynamic var email: String = ""

    @objc dynamic var name: String = ""

    @objc dynamic var phone: String = ""

    @objc dynamic var uid: String = ""

    @objc dynamic var username: String = ""

    @objc dynamic var website: String = ""

    @objc dynamic var birthday: Date = Date()

    

    override class func primaryKey() -> String? {

        return "uid"

    }

}



extension RLMUser {

    func toStruct() -> User {

        return User(address: address,

                    company: company,

                    email: email,

                    name: name,

                    phone: phone,

                    uid: uid,

                    username: username,

                    website: website,

                    birthday: birthday)

    }

}



extension User {

    func toObject() -> RLMUser {

        return RLMUser.build { object in

            object.uid = uid

            object.address = address

            object.company = company

            object.email = email

            object.name = name

            object.phone = phone

            object.username = username

            object.website = website

            object.birthday = birthday

        }

    }

}

乍一看似乎很方便的方法。但是如果你的结构不是那么小并且有更多的属性呢？如果你有太多类似User这样的结构时怎么办？如果您想在开发过程中为现有结构添加更多属性怎么办？

使用 Structify

struct User {

    var address: String = ""

    var company: String = ""

    var email: String = ""

    var name: String = ""

    var phone: String = ""

    var uid: String = ""

    var username: String = ""

    var website: String = ""

    var birthday: Date = Date()

}



class RLMUser: Object {

    //you only set the primaryKey as usual 

    override class func primaryKey() -> String? {

        return "uid"

    }

}



extension RLMUser: StructConvertible {

    typealias StructType = User

}



extension User: ObjectConvertible {

    typealias ClassType = RLMUser

}

你唯一需要做的就是让你的结构符合ObjectConvertible协议并创建一个 Objective-C 对类并符合StructConvertible协议。
