Apple Inc is overhauling how it tests software after a swarm of bugs marred the latest iPhone and iPad operating systems, according to people familiar with the shift.

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.
