A SwiftUI calendar library for building fully customizable calendar interfaces in iOS apps.
OBCalendar is a SwiftUI-based calendar library for iOS that enables developers to create customizable calendar interfaces. It provides a flexible structure for modifying day, month, and year views with support for locale configuration, date ranges, and performance optimizations like lazy loading.
iOS developers using SwiftUI who need to implement custom calendar interfaces in their applications, particularly those requiring extensive visual customization or specific layout behaviors.
Developers choose OBCalendar for its deep customization capabilities through dedicated modifiers for each calendar component, built-in performance optimizations like lazy loading, and the flexibility to create calendars from scratch using OBBaseCalendar for complete control.
OBCalendar is designed for simplicity and customization, it allows you to build beautiful and functional calendar interfaces effortlessly.

Provides dayModifier, monthModifier, and yearModifier for granular control over each calendar component, allowing custom views for days, months, and years as shown in the examples.
Supports both vertical and horizontal scrolling axes, enabling alternative navigation like horizontal month views, demonstrated in the horizontal scroll example.
Includes lazy loading options (lazyDays, lazyMonths) to improve performance with large date ranges, with specific guidance on when to use them for optimal results.
Offers selectable modifiers for date range selection, simplifying implementation for apps requiring interactive date picking, as illustrated in the range selection code snippet.
The README specifies that modifiers must be written in a strict order (dayModifier -> monthModifier -> yearModifier), which can be error-prone and non-intuitive for developers.
For programmatic scrolling, lazyYears must be set to false, loading all subviews into memory and potentially negating performance benefits in scroll-intensive use cases.
Cannot be integrated into UIKit-based projects, restricting its use to teams that have fully adopted SwiftUI for their iOS development.
