You whould init anywhere the SonogramView() as nib or fram - doesnt matter..
letsView:SonogramView=SonogramView()
Provide your fileURL like:
sView.addDurationOfFileWith(url: fileUrl!)
And just invoke the magic!
sView.convertToPoints()

import PlaygroundSupport
varfileUrl:URL?do{
fileUrl =PlaygroundSupport.playgroundSharedDataDirectory.appendingPathComponent("test.m4a")
// User/Documents/Shared Playground Data
}catch{print(error)}varwaveView:SonogramView=SonogramView()
waveView.addDurationOfFileWith(url: fileUrl!)
waveView.convertToPoints()
// And you are done!
// Customization of view
waveView.backgroundColor =.clear
letview=UIView(frame:CGRect(x:0, y:0, width:300, height:200))
view.backgroundColor =.white
view.addSubview(waveView)
waveView.frame.size.width = view.frame.width
waveView.frame.size.height = view.frame.height
waveView.center = view.center
PlaygroundPage.current.liveView = view // Showing in liveView with xCode Playground
