The SpeakToMe sample app is not working on my machine. What should I do?

Link: https://developer.apple.com/library/content/samplecode/SpeakToMe/Introduction/Intro.html#//apple_ref/doc/uid/TP40017110

I get the following log output from Xcode:

objc[7340]: Class PLBuildVersion is implemented in both /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/System/Library/PrivateFrameworks/AssetsLibraryServices.framework/AssetsLibraryServices (0x11ea84998) and /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/System/Library/PrivateFrameworks/PhotoLibraryServices.framework/PhotoLibraryServices (0x11e8a9d38). One of the two will be used. Which one is undefined.

I even allowed the ability to use the Speech Recognition API component of iOS 10.10.

What should I do?
