Hi there,
I am trying to get this example to work that was provided by Apple: https://developer.apple.com/library/content/samplecode/SpeakToMe/Introduction/Intro.html.
However, I am getting a SIGABRT error. I know that this can occur due to a variety of reasons, however, there appears to be no issue in the Storyboard. A couple of things to note, I converted the code to Swift 4 as per the prompts given in XCode 9.3, and I am running the application on an iPhone simulator. The below code is what I receive when the app crashes (the app builds fine but crashes as soon as I press the "Start Recording!" button):

Anyone have any ideas? It's stumped me for far too long. Cheers.
