Question 1

How to add interactive gestures to iOS view controller transitions with Transition?

Accepted Answer

Transition provides built-in support via the TransitionInteractionController; you define gesture recognizers and tie them to the transition context, as outlined in the custom interaction documentation and examples like TabBarTransitionsExample.

Question 2

Transition vs Hero for Swift animations: which is better?

Accepted Answer

Transition is more modular and lower-level, ideal for custom, interruptible transitions with fine-grained control, while Hero offers easier drop-in animations but less flexibility for complex interaction handling. Choose based on need for customization vs. simplicity.

Question 3

Does Transition support shared element transitions in Swift?

Accepted Answer

Yes, Transition includes shared element support to animate elements moving between views, demonstrated in the ModalTransitionsExample with cohesive visual effects across modal presentations.

Question 4

How to handle transition cancellation in iOS using Transition?

Accepted Answer

Transition automatically manages interruption logic through its robust architecture; you define animation layers and use the completion callbacks to clean up, ensuring smooth reversal or cancellation as per the library's design.

Question 5

Is Transition compatible with SwiftUI?

Accepted Answer

No, Transition is built for UIKit and iOS view controller transitions; it does not support SwiftUI's declarative syntax, so it's best suited for traditional UIKit-based projects.

Question 6

What are the performance implications of using Transition for complex animations?

Accepted Answer

Transition uses UIViewPropertyAnimator and modular components, which generally offer good performance, but complex animations with many layers or shared elements may require careful optimization to avoid frame drops.
