According to VisionMobile's State of the Developer Nation Q3, 2016 report, Android now has 79 percent mindshare within the mobile development industry compared to 61 percent for iOS. "Leaping to a new record for any platform since we started measuring, Android now has 79 percent mindshare amongst mobile developers," the report says. "While Android has been ahead of iOS for almost as long as it has existed, that lead has primarily been driven by greater adoption amongst hobbyists and those building apps as a sideline. Now we see 80 percent of those building apps professionally target Android. This is also reflected in the priorities of professional developers, with Android up 7 percentage points in the last six months, 47 percent of developers now consider it their primary platform."
VisionMobile says that only 31 percent of professional developers cite iOS as their primary platform; that's down from 39 percent six months ago. Still all is not lost for iOS. The report adds, "Developers are not abandoning the platform. Shifting developer priorities towards Android are quite a long-leading indicator for device sales, and Apple are already making big moves to counter this trend. Swift is a boost to iOS developer productivity. Cutting app review times increases iteration speed."
