Question 1

Is YapAnimator still maintained?

Accepted Answer

No, YapAnimator is archived and no longer maintained. The developers recommend using Apple's built-in spring animations for new projects, as stated in the README note, though the code still works if forked.

Question 2

How to animate a custom type with YapAnimator?

Accepted Answer

Conform your type to the Animatable protocol by representing it as an array of Doubles, then create a custom animator with initialValue, willBegin, and eachFrame callbacks, as shown in the square frame example in the README.

Question 3

YapAnimator vs UIKit spring animations: which should I use?

Accepted Answer

For simple, standard animations, UIKit springs are sufficient and better supported. YapAnimator offers more flexibility and interruptibility for complex interactions, but it's deprecated, so UIKit or SwiftUI animations are safer for new projects.

Question 4

Can YapAnimator be used with SwiftUI?

Accepted Answer

YapAnimator is designed for UIKit and AppKit, not SwiftUI. While you might bridge it via UIViewRepresentable, it's not ideal; SwiftUI's native .spring() animations are the recommended alternative for modern development.

Question 5

How do I apply gesture velocity to animations in YapAnimator?

Accepted Answer

Capture gesture velocities in state handlers (e.g., .changed) and use the force application feature to dynamically update animations, as demonstrated in the squircle example where pan gestures control cornerRadius and position.

Question 6

What platforms does YapAnimator support?

Accepted Answer

YapAnimator only supports iOS and macOS development. It does not support other Apple platforms like watchOS or tvOS, or non-Apple systems, limiting its use in broader applications.
