Question 1

How to chain animations sequentially in Cheetah?

Accepted Answer

Use the chainable API with .wait() calls between animation properties; for example, .move(100,0).wait().rotate(M_PI) runs animations one after another, as shown in the serial execution example in the README.

Question 2

Cheetah vs UIKit animations: which is better for iOS apps?

Accepted Answer

Cheetah excels for complex, chainable animations with easings and springs, while UIKit's UIView.animate is simpler for basic tasks. Choose Cheetah if you need advanced timing control or custom properties, but stick with UIKit for straightforward, built-in animations.

Question 3

Is Cheetah compatible with SwiftUI?

Accepted Answer

No, Cheetah is designed for UIKit and tvOS, not SwiftUI. For SwiftUI projects, you'd need to bridge it or use native SwiftUI animation modifiers, which might limit its usefulness in modern Apple ecosystems.

Question 4

How to add spring physics to UI elements with Cheetah?

Accepted Answer

Call .spring() on animation properties, optionally with tension and friction parameters; e.g., .move(200,0).spring(tension:100, friction:4).run(), as demonstrated in the springs section of the README.

Question 5

What are the performance implications of using Cheetah over Core Animation?

Accepted Answer

Cheetah uses CADisplayLink for smooth frame updates, but it may add overhead for very simple animations compared to Core Animation. For complex sequences, it's efficient, but benchmark for critical performance needs as the README doesn't provide benchmarks.

Question 6

How to animate custom properties like corner radius with Cheetah?

Accepted Answer

Extend CheetahProperty to support custom properties, referencing CheetahViewProperties.swift in the codebase; this requires manual Swift coding, as outlined in the 'Animate custom properties' section of the README.
