Calculation of local times of sunrise, solar noon, sunset, azimuth, elevation based on the calculation procedure by NOAA
CocoaPods is a dependency manager for Cocoa projects. For usage and installation instructions, visit their website. To integrate SolarNOAA into your Xcode project using CocoaPods, specify it in your Podfile:
pod 'SolarNOAA', '~> 1.0.0'Carthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks. To integrate SolarNOAA into your Xcode project using Carthage, specify it in your Cartfile:
github "rlxone/SolarNOAA" ~> 1.0.0Swift Package Manager is a tool for automating the distribution of Swift code and is integrated into the swift compiler.
Once you have your Swift package set up, adding SolarNOAA as a dependency is as easy as adding it to the dependencies value of your Package.swift.
