You can use "rate"

private var player: AVPlayer?
....
player?.rate = 1.25

The speed of playback depends upon the value for the rate value; greater than 1.0 is faster, and for slow playback, use less than 1.0.

You can increase or decrease the rate by this single line code:

// change the rate

The current rate of playback.

var rate: Float

Docs

A value of 0.0 means pauses the video, while a value of 1.0 play at the natural rate of the current item. Rates other than 0.0 and 1.0 can be used if the associated player item returns YES for the AVPlayerItem properties canPlaySlowForward or canPlayFastForward. Negative rate value ranges are supported if the player item returns YES for the canPlayReverse, canPlaySlowReverse, and canPlayFastReverse properties.
