Huh, well I never... I wonder when they just became apps within Finder!!
 
I'll add these into Alfred 4.0.8

Thanks for the explanation! Kind of wish AirDrop was supported natively in Alfred. I spent a whole night trying to write a perfect AppleScript for this before realizing I could just create a workflow to launch the AirDrop app inside Finder

AFAIK, the reason is that the contents of application bundles aren't indexed, so applications within other applications, like Airdrop.app or Alfred Preferences.app, won't show up in a search of the metadata index. They need to be specifically handled as special cases, which Spotlight does for Airdrop.app, but Alfred doesn't. Similarly, you can't launch Alfred Preferences.app via Spotlight.

This workflow allows you to invoke AirDrop in Alfred by typing airdrop.

Compared to hackish solutions that require AppleScript such as this and this, this simply executes airdrop.app directly, giving you the same experience as what you'd get when you type airdrop in Spotlight, e.g. it won't create duplicates if you already have one or more AirDrop windows or tabs opened, and lauching AirDrop won't bring all Finder windows to the front.
 
I'm actually a bit curious about why Alfred couldn't find airdrop.app after I added /System/Library/CoreServices/Finder.app/Contents/Applications/ to search scope. Until that works in Alfred, this is probably the best solution.
