I built a calendar package for iOS that focuses on modularity, customization, and performance.

Why I built it
I kept rewriting calendars across projects and couldn’t find something that was both flexible and performant. Most solutions were either pure SwiftUI with corresponding bugs and limitations, UIKit-heavy (fast but harder to integrate cleanly) or some abandoned packages.
Key ideas
- Highly modular architecture — use only the pieces you need
- Fully customizable UI and behavior
- SwiftUI-first API
- UIKit under the hood for smooth scrolling & performance
- Native iOS feel
Example use cases
- Scheduling apps
- Habit trackers
- Fitness / activity apps
- Booking interfaces
- Timeline-based UIs
Would love feedback! Contributions welcome 🙌
