On Windows 10, it will be possible to run applications developed for Android and iOS

At the Build 2015 conference, Microsoft's vice president of operating systems, Terry Myerson, literally said the following:
“Windows Studio will allow developers to use any Java and C ++ code from Android applications in Windows 10 applications,” after which he added that the programs developed in Xcode used to create applications on iOS will also work on Windows 10.
That is, any application created for Android or iOS can be adapted for Windows 10 in a few clicks. This opens up enormous prospects for the platform, which has so far been criticized for the meager store: it will be possible to significantly expand the range of the current 300 thousand programs due to 1.3 million Android-applications and 1.2 million iOS-applications. They will have access to all the features of the Windows platform, including Microsoft Surface tablets, Lumia smartphones, the Xbox One console, Windows 10 for PCs and laptops, as well as the upcoming Microsoft HoloLens .
