Open Source Swift Calendar Software

CalendarKit is a Swift calendar UI library for iOS and Mac Catalyst. It looks similar to the Apple Calendar app out-of-the-box, while allowing customization when needed. CalendarKit is composed of multiple modules which can be used together or independently. CalendarKit requires EventDataSource to return an array of objects conforming to EventDescriptor protocol, specifying all the information needed to display a particular event. You're free to use a default Event class as a model or create your own class conforming to the EventDescriptor protocol. CalendarKit supports localization and uses iOS default locale to display month and day names. First day of the week is also selected according to the iOS locale. By default, CalendarKit looks similar to the Apple Calendar app and fully supports Dark Mode. If needed, CalendarKit's look can be easily customized.

LunarBar is a free, open-source macOS menu bar calendar designed for quick access to traditional lunar dates and everyday scheduling information. It displays a compact calendar without requiring users to open a separate full-screen application. The software supports Chinese lunar calendar information alongside standard Gregorian dates. Users can view public holidays and important calendar dates through its streamlined interface. Integration with macOS calendars provides convenient access to scheduled events and reminders. LunarBar emphasizes simplicity, offering essential calendar information without unnecessary interface complexity. Built with Swift, it operates as a sandboxed, signed, and notarized macOS application. It supports automatic update checking and installation through Homebrew.

SwiftWeather has been renamed to Swift Language Weather. Swift Language Weather is an iOS weather app developed in Swift 4. The app has been actively upgrading to adopt the latest features of iOS and Swift language. The current version is working with Xcode Version Xcode 9.1 (9B55). If you are using a different Xcode version, please check out the previous releases. We use Protocol-Oriented Programming in IBAnimatable open source projects. Value-based programming, we use immutable values anywhere. Icon fonts, weather icons, SwiftyJSON, core location, app indexing like CoreSpotlight and NSUserActivity. Unit tests, UI tests, and animations supported. Compile and run the app in your simulator. If you don't see any data, please check "Simulator" -> "Debug" -> "Location" to change the location.

SwiftDate is the definitive toolchain to manipulate and display dates and time zones on all Apple platform and even on Linux and Swift Server Side frameworks like Vapor or Kitura. From simple date manipulation to complex business logic SwiftDate maybe the right choice for your next project. From simple date manipulation to complex business logic SwiftDate maybe the right choice for your next project. SwiftDate can recognize all the major datetime formats automatically (ISO8601, RSS, Alt RSS, .NET, SQL, HTTP...) and you can also provide your own formats. Creating a new date has never been so easy! Date can be manipulated by adding or removing time components using a natural language; time unit extraction is also easy and includes the support for timezone, calendar and locales! Manipulation can be done with standard math operators and between dates, time intervals, date components and relevant time units!
