Android and Apple Platforms

Developers familiar with iOS and other Apple platforms use a number of different tools and technologies, such as Swift, Xcode, and SwiftPM. When beginning to work with the Android platform, much of the terminology around Android development may seem alien at first. But in general, each component of iOS development has an analogue in the world of Android development.

Skip handles translating some of these elements between Apple platforms and Android. This table outlines the various Apple-specific terms and maps them to their equivalent Android term, as well as highlighting whether Skip helps in the translation process.
