Why am I getting this?

Any reasons in particular? (It never happened before until today after updated xcode, and updated my project to swift 3)
Can someone please help?

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.
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:
> 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). One of the two will be used. Which one is undefined.
I still don't know what all this means. Has anyone found something to solve this issue?

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.
