尝试运行我的目标时抛出以下错误:
dyld: Library not loaded: @rpath/libswiftCore.dylib Referenced from: x/Xcode/DerivedData/x/Build/Products/Debug/PriorityQueue.framework/Versions/A/PriorityQueue Reason: image not found
我的目标是使用Swift编写的命令行工具(OSX).我正在使用Swift编写的Cocoa Framework(PriorityQueue).当我将框架上的EMBEDDED_CONTENT_CONTAINS_SWIFT设置为yes时,目标运行时带有以下警告:

然后崩溃(可能是无关的):
MyTargetName[99144:2157492] *** NSForwarding: warning: object 0x1014346a0 of class 'Swift._NSContiguousString' does not implement methodSignatureForSelector: -- trouble ahead Unrecognized selector -[Swift._NSContiguousString fileSystemRepresentation]
这是Xcode的一个问题,应该报告,还是我错过了某种设置?
解决方法
在您的“命令行工具”目标中…设置以下内容…
LD_RUNPATH_SEARCH_PATHS = @executable_path
(或者Xcode调用它们,“运行时搜索路径”)设置这个,@rpath,本质上说..“嘿,看看任何”工具“运行的文件夹,用于动态可加载的lib. (在这种情况下,它将是您的构建文件夹.
其他有用的@rpath组合涉及类似于可执行文件的相对路径(在某些情况下也可能是库或框架二进制文件),通过@loader_path.说如果lib被捆绑在一个框架内.它可能需要@ loader_path /框架等的LD_RUNPATH_SEARCH_PATHS.
