Question 1

How to animate view transforms with Interpolate?

Accepted Answer

Interpolate supports CGAffineTransform and CATransform3D interpolation. Define an Interpolate object with from/to transform values and apply them in the closure, as shown in the advanced usage examples for smooth transformations.

Question 2

Interpolate vs Lottie: which is better for gesture-driven animations?

Accepted Answer

Interpolate is ideal for real-time, code-based animations tied to gestures, offering direct control over Swift values. Lottie focuses on rendering JSON animations from design tools, making it better for pre-built visuals but less flexible for interactive updates.

Question 3

Can I use Interpolate with scroll view delegate methods?

Accepted Answer

Yes, Interpolate works well with scroll-driven animations. Map scroll progress to interpolation progress, similar to the pan gesture example, to create effects like parallax or fading during scrolling.

Question 4

How to create a bounce effect with Interpolate?

Accepted Answer

Use the SpringInterpolation function with adjustable damping and stiffness parameters. The README's advanced usage shows configuring spring animations for natural bounce, such as in shadow or view position changes.

Question 5

Does Interpolate work with SwiftUI?

Accepted Answer

Interpolate is built for UIKit and tvOS, so it requires bridging or wrapper code to integrate with SwiftUI's declarative syntax, which may add complexity compared to native SwiftUI animation APIs.

Question 6

How to handle multiple simultaneous animations in Interpolate?

Accepted Answer

Create separate Interpolate instances for each animation and update their progress in the same gesture handler, allowing coordinated effects like color and position changes together.
