Technical Details

• UI is built using SwiftUI.
• The lyrics are updated and fetched using Swift Concurrency and Swift Tasks
• The lyrics are stored into disk using CoreData.
• I interface with Spotify & Apple Music using their AppleScript methods as well as by subscribing to their playback state change notifications.
• I interface with Spotify and Apple Music's AppleScript methods by using Apple's provided ScriptingBridge interface.
• I additionally use private APIs to get the currently playing Apple Music song's iTunes ID, and use MusicKit to map that to an ISRC code
• I map Apple Music songs to equivalent Spotify ID using ISRC to display Lyrics fetched from Spotify for either platform
• Spiritual successor to LyricsX (95% more efficient, 0.1% CPU usage of Lyric Fever vs 3% of LyricsX)
• Technical write-up coming soon
