Video quality selection in iOS-CodePudding

I am working on video player app which streams video from m3u8 url. Due to apple limitation, I can't set specific video quality during playtime or startup. I am curious because i can see this feature supported in Youtube iOS app. Apple provides preferredPeakBitRate but it doesn't guarantee whether video will be played in that bitrate.

How do youtube able to achieve that video quality or maintaining specific video quality in iOS? Just let me know if i am doing anything wrong or missing anything. Thanks in advance

Try this

if let lastEvent = self.playerItem?.accessLog()?.events.last {
let selectedBitRate = lastEvent.indicatedAverageBitrate
selectedAverageBitRate = selectedBitRate
selectedIndex = variants.firstIndex(where: {$0.averageBitRate ?? 0 == selectedBitRate})

}
