LunaMac

A MacOS menu bar app for the phases of the moon. LunaMac calculates the current moon phase using your computer's system time. If the menu bar icon is a Ⓧ, something went wrong and LunaMac couldn't calculate the moon phase. You can try reloading from the icon's menu.

This project covers a number of basic use cases:

• Programmatically creating a status icon in the system menu bar
• Working with datetime objects, including datetime math
• Loading contents of a file packaged with the application
• Using a timer to run periodic background updates
• Setting and using user preferences to build the UI

There are some useful implementations for those new to Apple's programming paradigms. Swift adopts a lot of Objective-C concepts, which themselves are likely foreign if you don't already have a working knowledge of Objective-C.

• Using interface builder actions and outlets to work with window elements
• Working with object delegation
• Implementing a view controller to interact with windows
