watchOS 2

Apple previewed watchOS 2 on June 8, 2015. September 9's announcement promised September 16, but that was not the release: Chris Welch reported Apple's statement that day in The Verge postponing it over an unspecified bug. The official register dates release to September 21; the distinction is retained without inventing the technical cause.

Developers could run apps natively on the watch and access Digital Crown, microphone, speaker and sensors through new APIs. ClockKit provided complications. Notes also allowed apps without a nearby iPhone on known Wi-Fi networks; this did not make the watch cellular or guarantee every app worked independently.

Photo, Photo Album and Time-Lapse expanded faces; Time Travel explored data with Digital Crown. Nightstand made the watch a bedside alarm and Mail gained dictation, emoji and suggested replies. Activation Lock tied activation to the owner's Apple ID and password, without promising theft was impossible.

Notes separate versions: 2.1 added right-to-left interface and Arabic among other languages. 2.2 allowed multiple watches paired to one iPhone and added Nearby in Maps. These are not backdated to 2.0; the register dates 2.2 to March 21, 2016, with later milestones through 2.2.2, without builds.
