Apple’s developer relations have hit another sour note. At the company’s hardware event on Tuesday, where it announced new Apple Watch devices and iPads, Apple surprised developers with the news that it would be releasing the updated versions of its major software platforms, iOS 14, iPad OS 14, watchOS 14, and tvOS 14 on September 16, giving them less than a day to prepare.

The unexpected and accelerated timeline left many developers scrambling to ready their apps for App Review and has complicated developers’ plans for the iOS 14 launch day.
