Class PLBuildVersion is implemented in both/Applications
提问by Cristian Siles
Why am I getting this?
为什么我得到这个？
objc[3993]: Class PLBuildVersion is implemented in both /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/System/Library/PrivateFrameworks/AssetsLibraryServices.framework/AssetsLibraryServices (0x112bb0910) and /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/System/Library/PrivateFrameworks/PhotoLibraryServices.framework/PhotoLibraryServices (0x1129da210).

Any reasons in particular? (It never happened before until today after updated xcode, and updated my project to swift 3)
有什么特别的原因吗？（直到今天更新 xcode 后才发生，并将我的项目更新为 swift 3）
Can someone please help?
有人可以帮忙吗？

I'm not convinced on the suggestions given by fellow developers so I've kept looking around for an answer. I've found a thread that says that the problem seems to have been cased by the Facebook SDK. However I haven't installed the Facebook SDK (Cocoapod) yet on my project, however I'm using the Import Social to share on Twitter, so I removed the Import Social and the ran my project again.
我不相信其他开发人员给出的建议，所以我一直在四处寻找答案。我发现一个帖子说这个问题似乎是由 Facebook SDK 解决的。但是我还没有在我的项目中安装 Facebook SDK (Cocoapod)，但是我使用 Import Social 在 Twitter 上分享，所以我删除了 Import Social 并再次运行我的项目。
This time I didn't get the same Output on the debugger, I got this instead:

So the "Class PLBuildVersion is implemented in both" is gone:
所以“类 PLBuildVersion 在两者中实现”消失了：

I still don't know what all this means. Has anyone found something to solve this issue?
我仍然不知道这一切意味着什么。有没有人找到解决这个问题的方法？

Its not a compiler warning, its an Objective-C runtime warning, and it is not in any code that you control. You can safely ignore it, as you cannot fix it.
它不是编译器警告，而是 Objective-C 运行时警告，并且不在您控制的任何代码中。您可以放心地忽略它，因为您无法修复它。
