speeds
A list of user-selectable playback speeds to show in the playback speed control.
Declaration
var speeds: [AVPlaybackSpeed] { get set }Discussion
By default, this property value equals systemDefaultSpeeds. Setting this property to an empty array hides the playback speed selection user interface.
To set the playback speed programmatically, call the selectSpeed(_:) method, or set the value of the defaultRate property on the view controller’s associated player object.
