错误解决：dyld: Library not loaded: @

用纯Swift程序真机调试，出现以下异常，在模拟器可以跑，用OC写的也可以跑，为什么
dyld: Library not loaded: @rpath/libswiftCore.dylib Referenced from: /private/var/mobile/Containers/Bundle/Application/930B04BF-8608-4075-A3B9-7FE2669F02BC/myTry.app/myTry Reason: no suitable image found.

解决方法：

1. 退出 Xcode
2. 重启电脑
3. 找到 这个 DerivedData 文件夹 删除 (路径: ~/Library/Developer/Xcode/DerivedData)
4. 删除这个 com.apple.dt.Xcode 文件 (路径: ~/Library/Caches/com.apple.dt.Xcode)

然后 在运行 Xcode 就好了~~
