wtf is apple-design-templates?

Apple Design Templates is a curated catalog of separate SwiftUI starter projects for building apps on iPhone, iPad, and Mac. SwiftUI is Apple's toolkit for building app interfaces. Rather than one big shared codebase, each project in the catalog is its own independent repository with its own code, demo, documentation, tests, and release history, so you only pull in the one piece you actually need. The catalog follows three stated principles: it prefers Apple's own system interfaces and conventions over custom ones, every demo runs with built-in sample data so you do not need an account or a backend server to try it, and each project stays small enough to adapt rather than growing into a general-purpose framework. Four templates make up the main collection. Liquid Glass Tab Bars offers three different styles of tab navigation built around one shared selection model. Adaptive App Shell is an app navigation shell that adjusts between compact iPhone tabs and a full iPad sidebar layout. Live Activity and Dynamic Island Kit provides reusable building blocks for the Lock Screen and Dynamic Island displays that show glanceable live updates, such as a delivery or timer status. Mac Menu Bar Command Kit is a keyboard-driven menu bar app shell for building small Mac utilities like timers, clipboard tools, or quick notes. Alongside these four templates sits a separate developer tool called ResizeLint, a command-line checker that looks for layout assumptions in an iPhone app's code that break once that app can run in a resizable window, such as on a Mac or iPad. It works entirely on your own machine, produces reports in several formats, and is also available as a GitHub Action for automated checks. Each project supports recent versions of iOS, iPadOS, or macOS and is built with Swift 6. The overall catalog is released under the MIT license.
