How to make a progress bar indicating how much is already cached for the ios player?

Question

iOS

Hello!
I'm writing my first app for iOS :) I'm
using AVPlayer and caching. How can I make a progress bar of the current position of the file being played while indicating how much has already been cached (in a darker color, for example). Naturally with the ability to drag and drop to play from another moment.
Thanks in advance!

Or file KVO: watch AVPlayerItem.loadedTimeRanges, we need a null object in the array, we get the right time like this: CMTimeRangeGetEnd(range!.CMTimeRangeValue)
or pull such a function
func availableDuration() -> CMTime
{
let range = self.player?. currentItem?.loadedTimeRanges?.first as? NSValue
if (range != nil){
return CMTimeRangeGetEnd(range!.CMTimeRangeValue)
}
return kCMTimeZero
}
