不能在Objective-C单元测试中使用Swift类 [英] Can't use Swift classes inside Objective-C unit test

问题描述

我已按顺序关注此食谱在现有的Objective-C项目 MyProject 中使用Swift类。这很好。

I have followed this recipe in order to use a Swift class in an existing Objective-C project MyProject. That works fine.

但是，我仍然无法在同一项目的单元测试中使用相同的Swift类。编译器标记我的Objective-C单元测试所在的行 #importMyProjectTests-Swift.h，找不到文件。

However, I'm still not able to use the same Swift class in the same project's unit tests. The compiler marks the line where my Objective-C unit test says #import "MyProjectTests-Swift.h" with file not found.

如果尝试从默认 MyProjectTests 产品模块名称 c $ c>到 MyProject 按照这个（未答复的）问题。然而，编译器现在标记我的Objective-C单元测试说 #importMyProject-Swift.h的行，其中找不到文件。

If tried changing the test target's Product Module Name from its default MyProjectTests to MyProject as suggested in a comment to this (unanswered) question. However the compiler now marks the line where my Objective-C unit test says #import "MyProject-Swift.h" with file not found.

那么如何将Swift类集成到用Objective-C编写的（XCTest）单元测试中呢？ Apple是否提供任何食谱？

So how can one integrate Swift classes into (XCTest) unit tests that are written in Objective-C? Does Apple provide any recipe?

推荐答案

根据@ SushiGrassJacob的评论（参见这里）以下解决了这个问题：

As per @SushiGrassJacob's comment (see here) the following solves the issue:

1. 确保Swift类的目标是 MyProject 和 MyProjectTest 。


2. 在单元测试中，＃importMyProjectTests-Swift.h。
