Now it’s easier than ever to bring your creativity to all Apple platforms. The iOS Developer Program, Mac Developer Program, and Safari Developer Program are now the Apple Developer Program. Starting June 8, only one membership in the single Apple Developer Program is needed to build and distribute apps for iOS, OS X, and watchOS.
Developers previously on iOS or Mac programs have automatically been updated to the new membership. If you previously had both programs, your membership has been extended to include the sum of the days that remained in each program.
This is great news for developers as only one membership is required now to build and test apps on any Apple device
