I am using Audiokit in my project and recently I updated my Xcode 9.3. It says i need to update Audiokit as well. But when I updated, it seems I need to use try catch to start and stop audio kit. this is fine.

    oscillator = AKFMOscillator()
    oscillator!.amplitude = 0.0
    oscillator!.baseFrequency = Double(calibration.frequency)
    oscillator!.carrierMultiplier = 1.0
    oscillator!.modulatingMultiplier = HolmesMethod.warbleModulationFrequency / Double(calibration.frequency)
    oscillator!.modulationIndex = HolmesMethod.warbleModulationIndex
    oscillator!.rampTime = HolmesMethod.clickMillis / 1000.0


    AudioKit.output = panner
    do {
        try AudioKit.start()
    } catch  {
    }

    oscillator!.start()

    panner = AKPanner(oscillator, pan: calibration.channel == .Right ? 1.0 : -1.0)
    panner?.start()

can anyone please tell me what is wrong with my code? because it's working in the old version but not in the latest version.

It looks to me like you've set the oscillator's amplitude to zero so I am not sure what you're expecting to hear.

After too much effort I found that we need to start oscillator once AudioKit start. 

oscillator = AKFMOscillator()
oscillator!.baseFrequency = Double(calibration.frequency)
    oscillator!.carrierMultiplier = 1.0
    oscillator!.modulatingMultiplier = HolmesMethod.warbleModulationFrequency / Double(calibration.frequency)
    oscillator!.modulationIndex = HolmesMethod.warbleModulationIndex
    oscillator!.rampDuration = HolmesMethod.clickMillis / 1000.0


    panner = AKPanner(oscillator, pan: calibration.channel == .Right ? 1.0 : -1.0)
    AudioKit.output = panner
    do {
        try AudioKit.start()
        } catch  {
    }

    oscillator!.start()
    panner?.start()

But here i got some weird sound for once second at the time of AudioKit Start.
