A Swift library providing two UIView subclasses for implementing interactive card flip animations via pan gestures on iOS.
CardAnimation is an open-source Swift library for iOS that provides interactive card flip animations controlled by pan gestures. It solves the problem of implementing complex, gesture-driven card stack animations by offering two pre-built UIView components that handle the animation logic, allowing developers to focus on their app's content and design.
iOS developers building apps that require interactive, card-based user interfaces, such as flashcard apps, onboarding flows, or portfolio displays.
Developers choose CardAnimation because it offers a ready-made, easy-to-integrate solution for a specific and polished animation pattern, saving development time compared to building gesture and animation systems from scratch.

Handles all gesture recognition and animation logic, allowing developers to implement interactive card flips without managing low-level gesture events, as seen in the README's focus on encapsulated solutions.
Offers CardContainerView for simple image-based cards and CardAnimationView for customizable views, providing flexibility based on whether you need quick image integration or full view control.
Quick setup via protocol conformance; developers only need to implement a few methods like numberOfCards and cardNumber to supply content, reducing boilerplate code.
CardAnimationView efficiently reuses card views through the reusedView parameter in the data source, optimizing memory when displaying many cards.
Built for Swift 4.0 and iOS 8.0, which may cause compatibility issues with newer Swift projects and limit access to modern language features and APIs.
Relies on a wiki for technical points and has sparse overall documentation, making troubleshooting and advanced usage challenging for developers unfamiliar with the codebase.
To create custom card views, developers must subclass BaseCardView, adding complexity and reducing flexibility compared to composition-based or protocol-oriented approaches.
