Near the end of yesterday's WWDC keynote, Craig Federighi, Apple's senior vice president of software engineering, acknowledged that people have been asking for a long time whether Apple would ever merge the iPhone and Mac operating systems. His short answer? "No." The word "No" appeared in giant white letters on the colossal screen behind him. Within minutes, screenshots of the "No" had populated Twitter, some with memes attached.

Except, that “No” should have had an asterisk after it, because while Apple still plans to ship two distinct operating systems—one for mobile, one for desktop—the company has been working on bringing iOS apps to Mac hardware. In an exclusive interview with WIRED, Federighi said the frameworks for porting iPhone and iPad apps to the Mac have been in development for two years. He revealed some of the technical details around how this will work, and shared some of the types of iOS apps he believes make sense on the Mac.
