What is daily?

Daily is a small macOS app that changes your desktop wallpaper using a personal collection of photos the developer picked out on Unsplash. Instead of writing your own script to rotate wallpapers or relying on a generic wallpaper app, this project pulls from one curated set: pictures the author personally liked and saved to a public Unsplash collection. The project is written in Swift and built with SwiftUI, Apple's toolkit for building native Mac and iOS style interfaces, which means the app should feel like a normal, lightweight piece of Mac software rather than a heavy cross-platform tool. The README mentions "liquid-glass" as a topic, which is Apple's newer visual design language used in recent macOS and iOS updates, so the app's interface likely uses that translucent, glassy look. Beyond that, the README is very sparse. It shows a single screenshot of the app in action and a link to the Unsplash collection the wallpapers come from, but it does not explain how to install the app, whether it needs to be built from source in Xcode, how often the wallpaper changes, or whether there are any settings a user can adjust. There is no setup guide, no license information, and no description of system requirements beyond it being a macOS project. For a non-technical reader, the simplest way to think about this is: it is a personal wallpaper changer built by one developer for their own use, using photos they liked, and shared publicly on GitHub with a screenshot as the only real documentation. Anyone hoping to use it themselves would likely need to open the project in Xcode and build it manually, since there is no packaged download or installer described in the README. With only nine stars, this looks like a small side project rather than a polished, widely used tool.
