Usage

I'm using it with expanded UICollectionView, create a collection view and link the DataSource and Delegate to your ViewController, and add UICollectionViewDeleageFlowLayout

class ViewController: UIViewController,
    UICollectionViewDataSource,
    UICollectionViewDelegate,
    UICollectionViewDelegateFlowLayout { ....

Then add these methods:

   func numberOfSections(in collectionView: UICollectionView) -> Int {
       return 5
   }
   
   func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
       return 1
   }
   
   func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
       return collectionView.dequeueReusableCell(withReuseIdentifier: "cell", for: indexPath)
   }
   
   
   func collectionView(_ collectionView: UICollectionView,
                       layout collectionViewLayout: UICollectionViewLayout,
                       sizeForItemAt indexPath: IndexPath) -> CGSize {
       return CGSize(width: collectionView.frame.width, height: 250) // This is to restric the item width and heigth to achive the single item preview
   }

Tick 'Scrolling enabled' and 'Paging enabled' Checkboxes in storyboard UICollectionView properties

Then add this method and pass the offset of the scrolling for UICollectionView, and width of the UICollectionView, to the pageControl , setCurrentItem, Method

func scrollViewDidScroll(_ scrollView: UIScrollView) {
      let offSet = scrollView.contentOffset.x
      let width = scrollView.frame.width
      
      pageControl.setPageOffset(offSet/width)
      
      // OR
      let index = Int(round(offSet/width))
      pageControl.setPage(index) // This will animate the page controll transition, whenever the index is changed, no need to pass an offset of every scroll offset

  }

Then set any drawer you like in viewDidLoad Method :

pageControl1.drawer = ColorBlendDrawer()

or you can pick one of these

ColorBlendDrawer()
DropDrawer()
ExtendedDotDrawer()
JumpDrawer()
ScaleDrawer()
SlideDrawer()
SwapDrawer()
ThinWormDrawer()
ThinWormHeadsDrawer()
WormDrawer()
Scrolling()
Infinite()

Customization

ScaleDrawer(numberOfPages:Int? = 5,
            height: CGFloat? = 16,
            width: CGFloat? = 16,
            space: CGFloat? = 16,
            radius: CGFloat? = 16,
            currentItem: CGFloat? = 0,
            indicatorColor: UIColor? = .red,
            dotsColor: UIColor? = .lightGray)
