Apple Urges Engineers to Cut Down on iOS 19 Bugs and System Glitches
In a move that may come as no surprise, Apple is reportedly pushing its software engineering teams to significantly reduce bugs and system failures in the upcoming iOS 19 update. According to Bloomberg’s Mark Gurman, the company is emphasizing stability and performance this year, following recurring criticism over past iOS releases plagued by glitches and unreliable features.
Apple plans to unveil the developer preview of iOS 19 at WWDC 2025, with the public release scheduled for September. While recent iOS updates have not introduced groundbreaking changes, they have frequently been criticized for an abundance of bugs. Apple is now urging its teams to deliver a more robust and stable release with iOS 19.

Gurman notes that in addition to incorporating new AI features and interface improvements, Apple’s leadership has made it clear to engineers that reducing malfunctions and strengthening core functionality are top priorities. Despite good intentions, minimizing bugs is no easy task—especially within the fast-paced development cycle typical of Apple.
Complicating matters further is Apple’s internal dissatisfaction with the progress of its AI features. Many planned AI functionalities have faced delays, placing added pressure on engineering teams to develop new capabilities on a tight schedule. As more features are packed into the update, the risk of bugs naturally increases, making this a challenge that can’t simply be resolved by internal memos.
There are also rumors that iOS 19 will feature a significant design overhaul, potentially inspired by the semi-transparent, floating interface style seen in Apple Vision Pro. However, balancing an ambitious UI redesign with efforts to maintain system stability could limit the company’s bandwidth for introducing entirely new features.
So far, no major new features of iOS 19 have been confirmed, and it appears Apple’s focus remains largely on AI integration. This leaves the final form of iOS 19 uncertain, with some concerns that it may amount to little more than incremental updates like minor widget tweaks.
Perhaps this message should also be forwarded to Microsoft—Windows 11 continues to frustrate users with frequent bugs, even as support for Windows 10 nears its end. For many, sticking with Windows 11 feels like a compromise, underscoring how both tech giants are grappling with the challenge of shipping reliable, modern operating systems.
