Frequency change event - AudioKit & Swift

I'm using Swift 4 with the AudioKit Framework 4.0.4.

I'd like to track the frequency of the input microphone of my iOS device in real time.

Currently I'm using a timer calling the output-function that prints out oscillator.frequency every 0.1 seconds.

let timer = Timer.scheduledTimer( timeInterval: 0.1, target: self, selector: #selector(self.output), userInfo: nil, repeats: true)

func output() {
   print("Frequency: \(oscillator.frequency)")
}

But is there a way to just listen for the change of the oscillator.frequency struct? Maybe something like an event called every time if the oscillator.frequency was changed.
