Henri Lamiraux, vice president of engineering for iOS Apps and Frameworks at Apple, left the company and retired just a few weeks after the maker of the iPhone and iPad launched the latest iteration of its mobile operating system. Lamiraux joined the company in 1990 and was responsible for several patents such as the visual voicemail.

Lamiraux  took more responsibility in the development of the mobile OS while reporting to software engineering  senior vice president  Craig Federighi, who is in charge of both OS X and the iOS.

Mark Gurman of the tech blog 9to5Mac was first to scoop Lamiraux's retirement and was able to confirm it via email. It reported that the executive decided that the iOS 7 will be his last project and left the company a few weeks ago after Apple rolled out the iOS 7.0.3. The Apple VP also confirmed his retirement through his LinkedIn and Facebook pages.

"Sources within Apple's iOS division say Lamiraux is respected and he was in charge of developing the applications that come with iOS. The executive also led feature-implementation across the operating system, and he managed both bug-fixing processes and feature distribution to consumers. He also managed the frameworks within the operating system that power features and allow developers to build applications," Gurman's article stated.

Lamiraux was in charge of developing features, frameworks for app building, and bug fixing for the mobile operating system of Apple. After working as a Mac platform software engineer, he was promoted to a managerial post in 2000 for platform that was renamed as the OS X. He eventually became the director of engineering of the said department in 2004.

He moved to the Apps and Frameworks department for the development of iOS in 2005 as the software engineering director. Lamiraux became VP of this department in 2009. He is one of the engineers that helped create the iPhone since its inception.

It is not yet clear who will fill the position of Lamiraux and how his retirement will affect the development of future versions of the iOS. Apple is rumored to have started working on the iOS 8.

Lamiraux frequently appeared during developer sessions at Apple's Worldwide Developers Conference or WWDC.
