Since I built and started running app on iOS 10 simulator, I started getting logs such as :
objc[6880]: Class PLBuildVersion is implemented in both /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/System/Library/PrivateFrameworks/AssetsLibraryServices.framework/AssetsLibraryServices (0x120275910) and /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/System/Library/PrivateFrameworks/PhotoLibraryServices.framework/PhotoLibraryServices (0x12009f210). One of the two will be used. Which one is undefined.

Wonder how I fix them ? I never saw these on XCode 7.
I have the same issue, but there is something you can do to,
1) Go in Product -> Scheme -> Edit Scheme
2) Run Section on the left, select Argument Tab and in Environment Variable put this.
OS_ACTIVITY_MODE to value : disable.
For more information please find the below screenshot.
This will get rid of messages in the console.
But I still struggle with the PLBuildVersion is implemented in both....
I hope this helps you !
*** EDIT ****
I found that the issue was caused by Facebook SDK. I removed the framework from CocoaPods, installed it manually by copying the SDK in my project folder and I have no errors now.
check if your func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions:) in AppDelegate.swift is declared private, if yes, then remove the private keyword. It should work after that.
