我应该为这些模型使用协议吗？
Should I Be Using Protocols for these Models?
我正在使用 Dribbble API，目前我正在使用三个模型：
UserTeamShot
Shot 是 User 或 Team 上传到他们各自的作品集以供展示的东西。这可以是图像或动画。一个User可以属于多个Team，而一个Team可以有多个User。
这三个模型各有许多属性，我在下面提供了这些属性。
User 采用以下结构：
/// Encapsulates information about a Dribbble User.
public struct User {
// MARK: - Properties
/// The identifier of the User.
public var identifier: Int?
/// The name of the User.
public var name: String?
/// The username of the User.
public var username: String?
/// The `URL` for the User's Dribbble page.
public var htmlURL: URL?
/// The `URL` for the User's avatar image.

public var membersCount: Int?
/// The `URL` for the members of the Team.
public var membersURL: URL?
/// The `URL` for the Team Shots.
public var teamShotsURL: URL?
}
Shot 采用以下结构：
/// Encapsulates information about a Dribbble Shot.
public struct Shot {
// MARK: - Properties
/// The identifier of the Shot.
public var identifier: Int?
/// The title of the Shot.
public var title: String?
/// The description of the Shot.
public var description: String?
/// The size of the Shot.
public var size: CGSize?
/// The `URL` for the Shot's high-definition image.
public var highDefinitionImageURL: URL?
/// The `URL` for the Shot's normal image.
public var normalImageURL: URL?
/// The `URL` for the Shot's teaser image.
public var teaserImageURL: URL?
/// The number of views for the Shot.
public var viewsCount: Int?
/// The number of likes for the Shot.
public var likesCount: Int?

public var commentsCount: Int?

public var commentsURL: URL?
/// The `URL` for the Shot's Likes.
public var likesURL: URL?
/// The `URL` for the Shot's Projects.
public var projectsURL: URL?
/// The `URL` for the Shot's Rebounds.
public var reboundsURL: URL?
/// Whether the Shot is animated.
public var isAnimated: Bool?
/// The tags associated with the Shot.
public var tags: Array<String>?
/// The `User` that the Shot belongs to.
public var user: User?
/// The `team` that she Shot belongs to.
public var team: Team?
}
User 和 Team 有很多重复的属性，而 Shot 有一些 User 和 Team 有。如果我走这些模型的协议路线，将会有许多个协议实现。
在我的例子中，我没有理由拥有 Identifiable 类型或 WebsiteURL 类型的 Array 类型，或符合重复属性协议的任何其他类型。我将有 Shot 个 Array 个，它们属于 User 个或 Team 个。我还将 Arrays 用于 Users 和 Arrays 用于 Teams.
我是否应该为重复的属性实施协议并让 User、Team 和 Shot 符合它们，或者这会导致协议地狱，除了没有明显的好处之外正所谓"Swifty"?
那么像这样使用继承呢，
Common parent 获取 Shot、User 和 Team 的属性，Parent for user 和 team 仅获取 user 和 team 的属性有
Common parent
