The 4.2.2 update for Unity, the multiplatform game development software, adds support for iOS controllers, according to a recent post on Unity Technology's official blog.
"Like most mobile games developers, we've been closely following what important additions and changes the recently released iOS 7 update has made," the blog post reads. "One of the biggest and most exciting of Apple's initiatives is the standardization of game controllers for iOS-based platforms. So we're happy to tell you that, in addition to several important bug fixes for Xcode 5 / iOS 7 (Build&Run, WebCamTexture and status bar), Apple Controller support is included with 4.2.2!"
The blog post contains a brief Q&A that explains that controller support "plugs directly into the standard Unity Input API," and that Unity's iOS runtime will only load controller support if it's available on the device on which the game is running.
This announcement is the latest in Unity's move toward greater mobile support. In May 2013, Unity Technology announced that it was giving indie developers access to Unity's basic mobile publishing tools for free. Previous versions cost $800.
Apple announced that support for third-party game controllers was coming to iOS 7 earlier this year during its WWDC 2013 keynote.
