I'm using target is 10.0

Hi there,

Been using your framework for a while and it's been really solid! Just recently been running into a small issue - when I call the startRecording() function, it suddenly crashes at this point:

let inputNode = audioEngine.inputNode
(line 83 of SBSpeechRecognizer.swift)

This doesn't always happen, and I am not sure why it is happening. Weirdest part is this hasn't always happened (only started recently) but I haven't changed anything related to the audio component since I initially implemented your framework a couple months ago. Even now, it only happens randomly and occasionally (ironically making it a bit scarier!)

Do you have any suggestions as to what I should look into or what may be causing this? I would provide more error log info, but all Xcode is giving me is a list of memory addresses which doesn't seem to be very helpful.
