Building command-line user experiences with Swift
summary
Builds a real MusiCLI that searches Apple Music via MusicKit and can open a SwiftUI window from the terminal. Uses Swift Package Manager and swift-argument-parser (AsyncParsableCommand) with readLine for input, requests MusicKit auth, hits a missing bundle identifier error and fixes it by embedding an Info.plist bundle trick (Xcode: create info plist section in binary or matching linker flags in SPM). Styles output with ANSI sequences using AnsiTerminal and a spinner library, and launches NSApplication + HostingController to display artwork — end-to-end working demo.
