frameworks - MacOS Swift Framework 测试失败

Question

我有一个用 obj-c 和 swift 编写的框架。

现在我尝试运行一个相关的单元测试目标，但我得到这个错误:

2014-07-10 07:45:54.064 xctest[4908:303] The test bundle at /Users/steve/Temporary/Build/Products/Debug/SOGraphDB-Mac Tests.xctest could not be loaded because an unanticipated error occurred: Error Domain=NSCocoaErrorDomain Code=3587 "The bundle “SOGraphDB-Mac Tests” couldn’t be loaded because it is damaged or missing necessary resources."

知道根本原因是什么吗？该错误似乎与“未加载库:@rpath/libswiftAppKit.dylib”有关

两者(框架和测试包)编译时没有任何错误或警告(在 Beta2 中)

Answer 1

我有一个类似的问题，虽然我的是一个 iOS 测试目标，链接到一个 Swift 框架，但无法在 Xcode 6 GM 上运行。测试目标在 Xcode 6 的早期测试版上运行成功，但最终版本报告运行时错误:Library not loaded: @rpath/libswiftCore.dylib

我注意到一个较新的项目没有失败，所以我比较了build设置和测试代码。我能够通过三个步骤解决问题:

1. 测试目标需要将“嵌入式目标包含 Swift 代码”设置为"is"。这会告诉链接器将 Swift 运行时库添加到可执行文件中。

2. 测试目标需要“运行路径搜索路径”build设置的明确值。这告诉加载程序在哪里可以找到 Swift 运行时库。我从一个全新的测试目标中复制了以下设置:

   LD_RUNPATH_SEARCH_PATHS = $(inherited) @executable_path/../Frameworks @loader_path/../Frameworks
   

3. 测试用例需要显式导入链接框架使用的任何模块。在我的项目中，框架使用了 UIKit 但测试用例只使用了我的框架。当我向测试用例添加显式 import UIKit 时，链接问题就消失了。
