App Intents vs SiriKit Comparison
iOS 16+ modern Shortcuts + Siri integration
VS
SiriKit
iOS 10+ legacy Siri integration (Intents framework)
8 min readiOS
Quick Verdict
For new apps, App Intents is mandatory. For legacy SiriKit maintenance and iOS 10-15 support, it remains in use. Referencing SiriKit in iOS 16+-only projects is an anti-pattern. Migration takes 1-2 weeks for a medium-sized app.

Moderate. Built-in domains have equivalents; custom intents need to be rewritten as App Intents. A gradual approach works — new features use App Intents while legacy SiriKit stays in place.
