Changing UISlider Images with Swift

I'm trying to change the default images for UISliders with Swift. I'm editing didFinishLaunchingWithOptions in AppDelegate.

In Objective C you would do this:

UIImage *maxImage = [UIImage imageNamed:@"slider-track.png"];
[[UISlider appearance] setMaximumTrackImage:maxImage forState:UIControlStateNormal];

I've tried converting to Swift but have not been successful:

var maxImage:UIImage = UIImage (named:"slider-track.png")
UISlider.setMaximumTrackImage(image: maxImage, forState: UIControlStateNormal)

The first line is fine, but the second gives an error.

What is the correct syntax for the second line?

Thanks

From Doc Example

let leftTrackImage = UIImage(named: "slider_blue_track")
customslider.setMinimumTrackImage(leftTrackImage, for: .normal)

UIImage *img = [UIImage imageNamed:@"slider"];

UIImage *trackImg;

if (isiPad) 
{

[[UISlider appearance] setThumbImage:img forState:UIControlStateNormal];
[[UISlider appearance] setThumbImage:img forState:UIControlStateHighlighted];
trackImg = [UIImage imageNamed:@"ipad_img.png"];
}
else 
{

 [[UISlider appearance] setThumbImage:[self imageWithImage:img scaledToSize:CGSizeMake(27, 27)] forState:UIControlStateNormal];
[[UISlider appearance] setThumbImage:[self imageWithImage:img scaledToSize:CGSizeMake(27, 27)] forState:UIControlStateHighlighted];
 trackImg = [UIImage imageNamed:@"img.png"];
  }

[[UISlider appearance]  setMinimumTrackImage:trackImg forState:UIControlStateNormal];
[[UISlider appearance]  setMaximumTrackImage:trackImg forState:UIControlStateNormal];
