Research process
We start with Apple's public support pages, developer documentation, WWDC sessions and release notes. Community submissions are welcomed but never published without verification.
Fact checking
Every command is tested on current-generation hardware (iPhone, Apple Watch, HomePod, Mac, iPad, CarPlay) running the latest public OS release before being added or updated.
Sources
Where an external source is relied on, we link to it directly (Apple Support, Wikipedia, official developer docs). See FAQ for common references.
Update frequency
The catalogue is reviewed after each major iOS release, and continuously for reader-reported changes.
Corrections
See our Corrections Policy.
