Logger is the first developer console designed for Shortcuts.

Building complex shortcuts is now easier than ever! Use the Logger’s shortcut actions to write messages to the console. See them posted in realtime as your shortcut runs - no more Quick Look actions required.

Use the powerful filtering tools to drill down into the output. Filter by category, device, date, contents, search or tags.

All your messages are synced securely between your devices using iCloud and you can even export your logs to plain text or markdown.
