I have MacOS 10.14.1, Xcode 10.0, and the latest version of AudioKit. I was trying out the microphone analysis (https://audiokit.io/examples/MicrophoneAnalysis/) but I keep on getting an error. I used breakpoints and found that the error is on the line mic = AKMicrophone()

Here is my code:

import UIKit
import AudioKit

class ViewController: UIViewController 

 @IBOutlet weak var frequencyLabel: UILabel!

 var mic: AKMicrophone! 
 var tracker: AKFrequencyTracker!
 var silence: AKBooster!
 var frequency = 0.0

 override func viewDidLoad() 
 super.viewDidLoad()

 AKSettings.audioInputEnabled = true
 mic = AKMicrophone() //Error here
 tracker = AKFrequencyTracker(mic)
 silence = AKBooster(tracker, gain: 0)

 

 override func viewDidAppear(_ animated: Bool) 
 super.viewDidAppear(animated)

 AudioKit.output = silence

 do 
 try AudioKit.start()
 catch 
 print("AudioKit did not start!")
 

 Timer.scheduledTimer(timeInterval: 0.1,
 target: self,
 selector: #selector(ViewController.updateUI),
 userInfo: nil,
 repeats: true)

 

 @objc func updateUI() 
 let temp = tracker.frequency
 frequency = temp
 print("Frequency: " + String(frequency))
 frequencyLabel.text = String(format: "%0.1f", temp)
 

I'm not sure how to fix this error, and Google yielded nothing. The error that shows up is

AVAEInternal.h:70:_AVAE_Check: required condition is false: [AVAudioIONodeImpl.mm:911:SetOutputFormat: (format.sampleRate == hwFormat.sampleRate)]

*** Terminating app due to uncaught exception 'com.apple.coreaudio.avfaudio', reason: 'required condition is false: format.sampleRate == hwFormat.sampleRate'

Thanks.
