Adding a progressbar to mp3 AVAudioPlayer playing swift

I'm trying to set a progressbar and a label to indicate the % of a mp3 file being played. Do I need to set a NSTimer function or can I do it with the AVFoundation?

Accomplish what you want using the following information which is available by AVFoundation. Use duration of mp3 file which you can get by creating an AVAsset with your mp3 file. And use AVAudioPlayer.currentTime to get the current playback position of the currently playing audio file.Periodically check the value of currentTime and update the progress bar accordingly. You can use a while-loop to constantly check currentTime which will make the progress bar appear to increment smoothly. You could also use an NSTimer but depending on your time intervals the progress bar may not appear to increment smoothly but it may appear abrupt.

Alternatively you could use AVPlayer or AVQueuePlayer instead of AVAudioPlayer. With those you will create an AVPlayerItem from which you can get the duration of the current song by AVPlayer.currentItem.duration.
