Animation not smooth problem

[andy199609]

Why the animation of siri wave look so lag and not smooth?

The example has 0.1 in the timer

I wanted 60 frames per second, so I selected 0.016

waveTimer = Timer.scheduledTimer(timeInterval: 0.016, target: self, selector: #selector(evaluateWave), userInfo: waveView, repeats: true)
