Software chief Craig Federighi and lieutenants including Stacey Lysik announced the changes at a recent internal “kickoff” meeting with the company’s software developers. The new approach calls for Apple’s development teams to ensure that test versions, known as “daily builds,” of future software updates disable unfinished or buggy features by default. Testers will then have the option to selectively enable those features, via a new internal process and settings menu dubbed Flags, allowing them to isolate the impact of each individual addition on the system.
When the company’s iOS 13 was released alongside the iPhone 11 in September, iPhone owners and app developers were confronted with a litany of software glitches. Apps crashed or launched slowly. Cellular signal was inconsistent. There were user interface errors in apps like Messages, system-wide search issues and problems loading emails. Some new features, such as sharing file folders over iCloud and streaming music to multiple sets of AirPods, were either delayed or are still missing. This amounted to one of the most troubled and unpolished operating system updates in Apple’s history.
