注意:2天前我试着在苹果开发者论坛发帖，也没有收到任何回复
我真的被困在我的项目的这一部分，因为我想镜像的方式苹果有他们的护理视图设置显示任务给用户。我出于某种原因，不能子类化'OCKSurveyTaskViewController'作为我得到的错误是:
在作用域"中找不到类型'OCKSurveyTaskViewController'
我通过SPM 2或三次重新安装了CareKit，我弄不清楚为什么我不能子类化它，即使我看到确切的OCKSurveyTaskViewController.swift文件，它在代码中作为CareKit/iOS/Task/ViewController目录中的开放类列出。
有没有人能给我一些指导，或者另一种方式来显示我每天以另一种方式为用户建立的ORKTasks ?我更喜欢苹果在wwdc21 CareKit代码中使用的方法，但唉，我已经在这上面停留了太长时间，这是我下一步所需要的。
这是我的文件代码:
import UIKit
import CareKit
import CareKitUI
import CareKitStore
import ResearchKit
import os.log
class StudyTaskFeedViewController: OCKDailyTasksPageViewController, OCKSurveyTaskViewController {}
下面是OCKSurveyTaskViewController.swift文件的代码:

当我尝试从"恢复"中复制演示代码时，遇到了同样的问题。在我将我的项目设置与"恢复"进行比较后，我注意到我错过了添加"健康工具包"的功能。在我的目标应用的Sign&Capabilities。在我添加了这个功能之后，它工作了。
