Hey All! As it is obvious from the GIF, this project is a LoadingIndicator based on CoreAnimation.

The Usage is like real simple:
Download the code and drag-drop VKProgressHud.Swift in your project.

Then add a variable var hudView : VKProgressHud? in your Class.

Showing Hud:

hudView = VKProgressHud(crocImageName: "croc")
hudView?.showHUD(onView: self.view)

Please note that croc is the name of Image you want in the Animation.

Hiding Hud:

hudView?.hideHUD()

Editable Properties:

1. Image in the Animator.
   
2. Radius of animator from the variable named refreshRadius in VKProgressHud.Swift.
   
3. Size of the dot from the variable named dotLength in VKProgressHud.Swift.
   
4. Spacing of the dots from the variable named instanceCount in VKProgressHud.Swift.
   
5. Duration of the animation from the variable named animationDuration in VKProgressHud.Swift.
   
6. Also the colour codes from the line circle.backgroundColor in VKProgressHud.Swift.
   
7. Label text saying 'Loading' can be edited in in VKProgressHud.Swift.
   

Concepts used:

let rotatorImageLayer: CALayer = CALayer()
let replicatorCircleLayer = CAReplicatorLayer()
var circle = CALayer()
var shapeLayerForCroc = CAShapeLayer()
let gradientLabelLayer = CAGradientLayer()
