Apple Inc executives, seeking to improve the performance of iPhone software after months of reported quality issues, have decided to delay some key features originally planned for this fall’s update, according to a person familiar with the matter.

As part of an annual release of new iPhone models, Apple also usually rolls out a major iOS update each year. The current software version, iOS 11, added augmented-reality features, a file management app and business-user enhancements for the iPad. For iOS 12, Apple has been working on additions like a redesigned home screen app grid, a multiplayer mode for augmented reality games, and a merger of the third-party applications running on iPhones and Macs, the people said, asking not to be named discussing information that isn’t public.
