dyld: Library not loaded: @rpath/libswiftCore.dylib

最近接手了个老项目，真机运行时总报下面的错误：
dyld: Library not loaded: @rpath/libswiftCore.dylib，被折磨了两天，网上所有的方法基本上都试了，不见效果。

最后无意间看到下面的解决方案，试了下，it works for me ! so happy...

I was having this issue with running my Swift tests (but not my app). It 
turns out that the test needed to have more than 
@executable_path/Frameworks in it's Runpath Search Paths build 
setting for the test target. Setting the Runpath Search Paths to the 
following worked a charm for me:

$(inherited)
@executable_path/Frameworks
@loader_path/Frameworks

我的工程里面少加了@loader_path/Frameworks，加上后，奇迹发生了，真机跑起来了。。。
