Earlier this week, Swift creator and LLVM co-author Chris Lattner announced he will be leaving Apple later this month—he is headed to Tesla to lead its autopilot engineering team as Vice President of Autopilot Software.

Lattner, who oversaw development of Swift and Xcode as director of Apple’s Development Tools department, did not provide an explanation for his decision to leave the company, but “someone in Lattner’s circle of developer friends” told Business Insider that Apple’s culture of secrecy at least partially contributed to the move.

“He always felt constrained at Apple in terms of what he could discuss publicly — resorting to off-the-record chats, surprise presentations, and the like,” the person told us. “Similarly, I know he was constrained in recruiting and other areas. Eventually I know that can really wear people down.”

Lattner, who joined Apple in 2005, did not respond to the publication’s requests for comment, so the exact reason for his decision remains uncertain. He previously said the decision “wasn’t made lightly,” and that he plans to remain an active member of the Swift Core Team despite his departure.

What we do know is that Swift now has a large community of developers working on the programming language since it became open source in late 2015, so it is very possible that Lattner felt he was in a good position to pursue a new opportunity without jeopardizing future development of the language he created in 2010.

Swift, designed to work with Apple’s Cocoa and Cocoa Touch frameworks, was developed for iOS, macOS, watchOS, tvOS, and Linux. The programming language was introduced at WWDC 2014 and is viewed as an alternative to Objective-C. Lattner said Apple’s development of Swift will continue under Ted Kremenek.
