ViewAnimator is an open source Swift library from Marcos Griselli that provides a nice simple way to create complex user interface animations on components that implement the Animatable interface such as UIStackView, UICollectionView, and UITableView.
As the readme states:
ViewAnimator is a library for building complex iOS UIView animations in an easy way. It provides one line animations for any view included the ones which contain other views like UITableView and UICollectionView with its cells or UIStackView with its arrangedSubviews.
This snippet shows some animation code with ViewAnimator showing off the simple syntax and chaining:
let zoomAnimation = AnimationType.zoom(scale: 0.2)
let rotateAnimation = AnimationType.rotate(angle: CGFloat.pi/6)
collectionView.animateViews(animations: [zoomAnimation, rotateAnimation], duration: 0.5)
tableView.animateViews(animations: [fromAnimation, zoomAnimation], duration: 0.5)
This animation shows off a user interface created with ViewAnimator:
You can find ViewAnimator on Github here.
A nice up-to-date Swift based user interface animation library.

Yalta – A Micro Auto-Layout DSL That Simplifies Creating Your Layouts In Swift
2
Yalta is a Swift Auto Layout from Alexander Grebenyuk DSL allowing you too design your user interfaces with considerably more concise code. The entire library itself is only a single file with less than 250 lines of code.
Yalta draws inspiration from the popular objective-c PureLayout library, but rather simplifies Apple’s auto layout for a short learning curve.
The tool was released in response to Chris Eidhof’s article on creating a micro Auto Layout DSL.
You can find Yalta on Github here.
A nice tool for quickly creating layouts in Swift.
