DynamicButton
A Swift library for creating animated flat buttons with built-in symbols and custom style support.
What is DynamicButton?
DynamicButton is a Swift library for creating animated flat buttons with built-in symbols and custom style support. It solves the problem of implementing interactive buttons with smooth animations—like hamburger menus that transform into close buttons—without requiring custom drawing code. The library provides a collection of pre-designed symbols and an extensible API for creating custom button styles.
iOS and tvOS developers building applications with custom UI controls, particularly those needing animated navigation buttons, media controls, or interactive symbols. It's ideal for developers who want polished button animations without implementing Core Graphics drawing manually.
Developers choose DynamicButton for its ready-to-use animated symbols, smooth transitions, and easy customization. Unlike basic UIButton implementations, it provides a declarative API for button styles with built-in animations and extensibility for custom symbols.

Use Cases
Best For
- Implementing animated hamburger menu buttons in navigation bars
- Adding play/pause/stop controls with smooth state transitions
- Creating custom toggle buttons with animated icon changes
- Building media players with animated forward/rewind buttons
- Designing custom navigation controls with arrow symbols
- Developing iOS apps with flat design button requirements
Not Ideal For
- Projects requiring non-flat, skeuomorphic button designs with gradients or shadows
- Cross-platform applications targeting macOS, watchOS, or non-Apple ecosystems
- Teams that need buttons with complex, multi-step animations beyond simple style transitions
Pros & Cons
Pros
Provides built-in animations for switching between styles like hamburger to close, eliminating the need for manual Core Animation code.
Includes 25+ pre-built symbols such as arrows, play/pause, and download, covering common UI needs without custom drawing.
Supports custom styles via the DynamicButtonBuildableStyle protocol, allowing developers to create unique buttons tailored to specific designs.
Properties like lineWidth and strokeColor can be adjusted directly, enabling precise styling to match app themes.
Cons
All button styles are inherently flat, which may not suit projects requiring textured, dimensional, or heavily styled buttons.
Implementing custom symbols requires Core Graphics knowledge and is restricted to a maximum of four paths, adding development overhead.
Only supports iOS and tvOS, excluding other Apple platforms like macOS and watchOS, limiting cross-platform use.
