How to use MDCSwipeToChoose with Swift?

You need to create a bridging header to import the Objective-C library, or use CocoaPods with frameworks and add 'import MDCSwipeToChoose' in Swift files. The README provides detailed code examples for both approaches.

MDCSwipeToChoose vs other swipe libraries for iOS?

MDCSwipeToChoose is focused on simple left/right swipes with a pre-built Tinder-like UI, making it ideal for quick implementations. Other libraries might offer more features like multi-directional swipes or better SwiftUI support, but with added complexity.

Can I customize the swipe animation in MDCSwipeToChoose?

Yes, but customization is limited to basic options like colors and text; for advanced animations, you must use the onPan callback and manual UIView animations, as shown in the delegate method examples.

How to disable swiping in MDCSwipeToChoose?

Set the swipeEnabled option to NO in MDCSwipeToChooseViewOptions, allowing only programmatic swipes. The README includes Objective-C and Swift snippets for this.

Does MDCSwipeToChoose work with collection views?

Yes, you can use the UIView category to add swipe gestures to any UIView, including cells in collection views, by setting up options and implementing delegate callbacks for swipe events.

Is MDCSwipeToChoose still maintained?

The library appears inactive with no recent updates, so while it works for basic use, you may need to fork or adapt it for compatibility with latest iOS versions and Swift changes.

What is MDCSwipeToChoose?

MDCSwipeToChoose is an iOS library that enables developers to add Tinder-like swipe gestures to any UIView, allowing users to swipe left or right to make choices. It solves the problem of building interactive, gesture-driven interfaces quickly, such as flashcard apps or photo viewers, without writing complex gesture recognition code from scratch.

Target Audience

iOS developers building apps that require interactive swipe-based selection, like dating apps, learning tools, or content curation interfaces.

Value Proposition

Developers choose MDCSwipeToChoose because it provides a battle-tested, customizable solution for swipe interactions with both high-level components and low-level APIs, reducing development time and ensuring a smooth user experience.

Overview

Swipe to "like" or "dislike" any view, just like Tinder.app. Build a flashcard app, a photo viewer, and more, in minutes, not hours!

Use Cases

Best For

Building flashcard apps with swipe-to-answer functionality
Creating Tinder-like interfaces for content selection
Implementing photo viewers with swipe-to-like-or-delete features
Adding interactive swipe gestures to custom UI components
Prototyping gesture-driven iOS apps quickly
Developing learning or quiz apps with swipe-based navigation

Not Ideal For

Projects requiring multi-directional swipes (e.g., up/down or diagonal) for complex interactions
Teams exclusively using SwiftUI who need native integration without bridging headers
Apps needing highly customized swipe physics or animations beyond basic left/right gestures

Pros & Cons

Pros

Easy UIView Integration

Adds swipe functionality to any UIView using the UIView+MDCSwipeToChoose category, enabling rapid prototyping without custom gesture code.

Pre-built Tinder UI

Provides MDCSwipeToChooseView for a ready-to-use interface with customizable text and colors, similar to Tinder.app, as shown in the sample GIF.

Flexible Configuration

Offers MDCSwipeToChooseViewOptions to tailor swipe behavior, appearance, and callbacks through properties like likedText and onPan blocks.

Programmatic Control

Allows swiping views programmatically or disabling user gestures via options, giving developers fine-grained control over interactions.

Cons

UIKit-Only Dependency

Limited to UIKit projects, making it incompatible with SwiftUI and requiring cumbersome bridging headers or framework imports for Swift integration.

Basic Swipe Support

Focuses solely on left/right swipes with no built-in support for other directions or advanced gesture interactions, limiting flexibility for complex apps.

Aging Codebase

The library hasn't seen significant updates in years, which may lead to compatibility issues with newer iOS versions or Swift language changes.
