Question 1

How do I create a scrolling app intro with RazzleDazzle?

Accepted Answer

Subclass AnimatedPagingScrollViewController, set the number of pages, add views to contentView, and use keep(view: onPage:) to position them. The demo app provides a practical example with fade, scale, and transform animations.

Question 2

RazzleDazzle vs Lottie for iOS animations, which is better?

Accepted Answer

RazzleDazzle is ideal for scroll-driven, code-based animations with AutoLayout integration, while Lottie excels at rendering vector animations from After Effects. Choose based on whether you need dynamic, layout-aware effects or pre-designed vector graphics.

Question 3

Can I use RazzleDazzle with SwiftUI?

Accepted Answer

RazzleDazzle is built for UIKit and doesn't have native SwiftUI support. You might need to wrap it in UIViewRepresentable, but it's not designed for SwiftUI's declarative paradigm, so integration could be clunky.

Question 4

How to add a custom animation type in RazzleDazzle?

Accepted Answer

Conform to the Animatable protocol and extend Interpolatable for your property type. For example, create a class that subclasses Animation and implements animate(time:) to update the view's properties, as shown in the README for BorderWidthAnimation.

Question 5

Is RazzleDazzle still maintained?

Accepted Answer

The README indicates it's written in Swift 3.0, which suggests it might not be actively updated for newer Swift versions. Check the GitHub repository for recent commits or issues to assess current maintenance status.

Question 6

What are alternatives to RazzleDazzle for scroll animations?

Accepted Answer

Alternatives include JazzHands for Objective-C, or more general frameworks like UIView animations with scroll delegates. For modern approaches, consider SwiftUI's scroll view modifiers or third-party libraries like Motion.
