在带有 UIViewControllerRepresentable 的 SwiftUI 应用程序中使用 qualtrics

Question

我正在尝试使用 qualtrics 制作一个简单的 swiftui 应用程序，并且我正在尝试使用 uiviewrepresentable 来使其工作

@main
struct QualtricsPocApp: App {
var body: some Scene {
    WindowGroup {
        ContentView()
    }
}

init() {
    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
            // Override point for customization after application launch.
            // i have the actual intercept id's here i just removed them
            Qualtrics.shared.initializeProject(brandId: "brand", projectId: "proj", extRefId: "ref", completion: { (myInitializationResult) in print(myInitializationResult);})

            return true

      }
   }
}


struct QualtricsViewRep: UIViewControllerRepresentable {

typealias UIViewControllerType = UIViewController

func makeUIViewController(context: Context) -> UIViewController {
    let vc = UIViewController()
    Qualtrics.shared.evaluateProject { (targetingResults) in
        for (interceptID, result) in targetingResults {
            if result.passed() {
                let displayed = Qualtrics.shared.display(viewController: self, autoCloseSurvey: true)
            }
        }
    }
}

在 let displayed = ... 我不断收到错误“无法将类型 'QualtricsViewRep' 的值转换为预期参数类型 'UIViewController'”，如何将此代码作为 UIViewController 返回以在 swiftui 应用程序中使用，或者是否有一些我应该以其他方式解决这个问题？

不幸的是，我没有安装 Qualtrics，但我已经在 UIKit 中使用了它。我的假设是您需要创建 UIViewController 的实例。该视图控制器是 qualtrics 视图将呈现的内容。

最终，您将返回视图控制器，其中包含在其上呈现的质量视图。

struct QualtricsViewRep: UIViewControllerRepresentable {
     typealias UIViewControllerType = UIViewController

     func makeUIViewController(context: Context) -> UIViewController {
         let vc = UIViewController()
            Qualtrics.shared.evaluateProject { (targetingResults) in
                for (interceptID, result) in targetingResults {
                    if result.passed() {
                         DispatchQueue.main.async {
                            let vc = UIViewController()
                            let displayed = Qualtrics.shared.display(viewController: vc, autoCloseSurvey: true)
                         }
                    }
                }
            }
         return vc
     }

     func updateUIViewController(_ uiViewController: UIViewController, context: Context) {
         // your code here
     }
}
