使用@testable时，“模块未编译进行测试” [英] 'Module was not compiled for testing' when using @testable

问题描述

我正在尝试使用Swift 2的新 @testable 声明来将我的类公开给测试目标。但是我收到这个编译错误：

I'm trying to use Swift 2's new @testable declaration to expose my classes to the test target. However I'm getting this compiler error:

间隔是包含我试图公开的类的模块。如何摆脱此错误？

Intervals is the module that contains the classes I'm trying to expose. How do I get rid of this error?

推荐答案

在主目标中，您需要设置启用可测试性构建选项为是。

In your main target you need to set the Enable Testability build option to Yes.

根据以下@earnshavian的评论，这应仅用于调试版本，如苹果发行说明：Enable Testability构建设置应仅在您的Debug配置中使用，因为它禁止依赖于不从应用程序或框架导出内部符号的优化 https://developer.apple.com/library/content/ releasenotes / DeveloperTools / RN-Xcode / Chapters / Introduction.html＃// apple_ref / doc / uid / TP40001051-CH1-SW326

As per the comment by @earnshavian below, this should only be used on debug builds as per apple release notes: "The Enable Testability build setting should be used only in your Debug configuration, because it prohibits optimizations that depend on not exporting internal symbols from the app or framework" https://developer.apple.com/library/content/releasenotes/DeveloperTools/RN-Xcode/Chapters/Introduction.html#//apple_ref/doc/uid/TP40001051-CH1-SW326
