无法将“X"类型的值转换为预期的参数类型“X"

本文介绍了无法将“X"类型的值转换为预期的参数类型“X"的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

8的Xcode和斯威夫特今天有真悲哀让我:(

Xcode 8 and Swift 3 made me really sad today :(

请看一看，告诉我您是否遇到过这样的事情，以及是否可以修复它.我一直在尝试不同的解决方案，其中包括:

Please have a look and tell me if you ever had something like this and if it's possible to fix it. I've been trying different solutions, among them:

Cmd + Shift + K

Cmd + Shift + Option + K

删除派生数据

更改使用的结构(它是我代码中的嵌套结构)，将其展平，更改为非常基本的结构

更新 1:

这是代码(虽然我认为这不一定是与我的实现有关的问题)，它在我的测试目标中:

Here's the code (although I think it's not necessarily a problem related to my implementation), it's in my tests target:

let viewModelStub: Quiz.NewRoundDetails.ViewModel = Quiz.NewRoundDetails.ViewModel(roundNumber: "", score: "", proposedAnswerParts: [ Quiz.NewRoundDetails.ViewModel.AnswersForComponent(answers: []), Quiz.NewRoundDetails.ViewModel.AnswersForComponent(answers: []), Quiz.NewRoundDetails.ViewModel.AnswersForComponent(answers: [])]) _ = viewController.view viewController.display(roundModel: viewModelStub)

这里是结构:

struct Quiz { struct NewRoundDetails { struct Response { let roundNumber: Int let score: Int } struct ViewModel { let roundNumber: String let score: String let proposedAnswerParts: [Quiz.NewRoundDetails.ViewModel.AnswersForComponent] struct AnswersForComponent { let answers: [String] } } } }

在 viewController 中，事情看起来像这样:

And in viewController things look like this:

func display(roundModel: Quiz.NewRoundDetails.ViewModel) { ... }

我觉得没什么特别的.我刚刚发现了一件事 - 代码在应用目标端运行良好，但在测试目标端不起作用.

Nothing so unusual I think. I have just discovered one more thing - the code works fine on the app target side, it doesn't work on tests target.

我没有更多想法 atm... 你能帮我吗?我也创建了雷达

I don't have more ideas atm... Can you help me? I have created radar as well

推荐答案

好的，我知道了...

我已经使用 @testable 导入了我的应用程序模块，并且我已经将带有模型类的 .swift 文件添加到测试目标.可能是 .已创建 Quiz.NewRoundDetails.ViewModel 而不是 .Quiz.NewRoundDetails.ViewModel

I've imported my app's module with @testable and also I've had added my .swift file with model classes to the test target. Probably <MyTestModule>. Quiz.NewRoundDetails.ViewModel have been created instead of <MyAppModule>. Quiz.NewRoundDetails.ViewModel
