Apple Says watchOS 1 Updates to End in 2018; App Sizes Can Now Be 75MB

Apple has announced to developers they want them to “update your watchOS apps”, to ensure their apps can take advantage of the latest watchOS 4 SDK for “increased performance, new background modes for navigation and audio recording, built-in altimeter capabilities, direct connections to accessories with Core Bluetooth, and more.”

The company also has announced the increase of a watchOS app bundle from 50MB to 75MB.

Also, as of April 1, 2018, Apple says updates to older watchOS 1 apps “will no longer be accepted”. Updates now need to be native apps developed with watchOS 2 SDK or later, while new watchOS apps “should be built with” watchOS 4 or later.

Earlier this afternoon, Apple released iOS 11.1.2 for iOS devices.
