Question 1

How to animate custom properties with Yet Another Animation Library?

Accepted Answer

Use SpringAnimation or MixAnimation with getter and setter closures, or extend NSObject to use yaal.animationFor for key-based registration, as shown in the README examples for animating volume or other custom attributes.

Question 2

YAAL vs Facebook Pop: which is better for Swift projects?

Accepted Answer

YAAL is optimized for Swift with native protocol-oriented design and SIMD performance, making it faster and more type-safe than Pop. However, Pop has a larger ecosystem, so YAAL is best for new Swift projects focused on gesture interactions.

Question 3

Can I use YAAL with SwiftUI?

Accepted Answer

No, YAAL is built for UIKit and integrates with UIView properties. For SwiftUI, you'd need to bridge via UIViewRepresentable, which adds complexity compared to native SwiftUI animation APIs.

Question 4

How to chain animations in YAAL?

Accepted Answer

Use the `=>` operator to link value changes, such as view.yaal.scale.value => view.yaal.alpha, which automatically animates alpha based on scale changes, simplifying reactive workflows.

Question 5

What are the performance benefits of YAAL over UIKit animations?

Accepted Answer

YAAL leverages SIMD instructions and Swift generics for calculations, reducing overhead in gesture-driven scenarios. It's ideal for complex, interactive animations where UIKit's UIView.animate might stutter.

Question 6

How to handle custom animatable types like IndexPath?

Accepted Answer

Conform the type to VectorConvertible by defining vector conversion methods, as demonstrated in the README for IndexPath, enabling type-safe animations with YAAL's API.
