Yotei - Highly modular & customizable SwiftUI calendar

Source: Dev.to

Overview

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 🙌
