Zac Hall, 9to5Mac:
Apple has detailed an upcoming feature included in the new iOS 11.2 developer beta called SiriKit for HomePod. When HomePod launches in December, SiriKit for HomePod will allow developers to use the smart speaker as an access point to sending commands to their apps on iPhone and iPad.
No way to test this yet, as far as I know. Will Apple ship a HomePod simulator for Xcode before the HomePod itself ships?
Haven’t looked into ways of testing it, but I’ll bet a select group of partners have early access to the tools needed and it’ll launch with those partners first and more robust development testing comes out after.
