ToosieSlide

ToosieSlide is a library that offers a custom flow layout that simulates a paginated collection view, with the cell always staying in the middle. In other words, a carousel. In addtion ToosieSlide supports automatic cell resizing and alpha difference between focused and unfocused cells.

ToosieSlide is fully documented here

Unless you have been living under a rock or born in 2030, ToosieSlide gets its name and its logo is inspired by Drake's Toosie Slide

3. Code Example

Using UICollectionViewCarouselLayout

lazy var collection: UICollectionView = {
  let carouselFlow = UICollectionViewCarouselLayout()
  carouselFlow.itemSize = CGSize(width: DemoCell.width, height: DemoCell.height)
  carouselFlow.minimumLineSpacing = 10
  let collection = UICollectionView(collectionViewCarouselLayout: carouselFlow)
  collection.register(DemoCell.self, forCellWithReuseIdentifier: DemoCell.identifier)
  return collection
}()

Customizing UICollectionViewCarouselLayout

let carouselFlow = UICollectionViewCarouselLayout()
carouselfFlow.lowestVelocitySensitivity = 0.3
carouselfFlow.focusedItemScaleFactor = 1
carouselfFlow.focusedItemAlphaValue = 1
carouselfFlow.nonFocusedItemsScaleFactor = 0.5
carouselfFlow.nonFocusedItemsAlphaValue = 0.7

4. Roadmap

• support continuous swiping

Generate the project

To generate this project locally, you need xcodegen. It is a great tool to customize a project and generate it on the go.

You can either install it manually following their steps, or just run my setup.sh script. It automatically installs Homebrew if it is missing, installs xcodegen, removes existing (if present) .xcodeproj, run xcodegen and moves configuratiom files to their appropriate place.
