使用 SwiftUI 和 MVVM 模式映射单个响应对象

我有一个简单的用户配置文件模型，它作为单个节点从 JSON API 返回。

（模型）UserProfile.swift

struct UserProfile: Codable, Identifiable {
    let id: Int
    var name: String
    var profile: String
    var image: String?
    var status: String
    var timezone: String
}

(服务) UserProfileService.swift

class UserProfileService {    
    func getProfile(completion: @escaping(UserProfile?) -> ()) {
        guard let url = URL(string: "https://myapi.com/profile") else {
            completion(nil)
            return
        }
        
        var request = URLRequest(url: url)
        
        request.setValue("application/json", forHTTPHeaderField: "Content-Type")
        request.setValue("application/json", forHTTPHeaderField: "Accept")
        request.httpMethod = "GET"
        
        URLSession.shared.dataTask(with: request) { data, response, error in
            guard let data = data, error == nil else {
                DispatchQueue.main.async {
                    completion(nil)
                }
                return
            }
            
            do {
                let profile = try JSONDecoder().decode(UserProfile.self, from: data)
                
                DispatchQueue.main.async {
                    completion(profile)
                }
            } catch {
                print("ERROR: ", error)
            }
        }.resume()
    }
}

（视图模型）UserProfileViewModel.swift

class UserProfileRequestViewModel: ObservableObject {
    @Published var profile = UserProfile.self
    
    init() {
        fetchProfile()
    }
    
    func fetchProfile() {
        UserProfileService().getProfile { profile in
            if let profile = profile {
                self.profile = UserProfileViewModel.init(profile: profile)
            }
        }
    }
}

class UserProfileViewModel {
    var profile: UserProfile
    
    init(profile: UserProfile) {
        self.profile = profile
    }
    
    var id: Int {
        return self.profile.id
    }
}

有人可以告诉我需要在self.profile = UserProfileViewModel.init(profile: profile)上面放什么，因为这会导致错误“无法将'UserProfileViewModel'类型的值分配给'UserProfile.Type'”？

如果我有一个数据循环，那么像下面这样循环就没有问题，但是我如何处理单个节点？

if let videos = videos {
    self.videos = videos.map(VideoViewModel.init)
}
