Apple Developer

Apple Developer, stylized as   Developer, is a subscription-based website maintained by Apple Inc. to provide support to developers of its iOS, iPadOS, macOS, tvOS, and watchOS platforms.

History
The site was formerly known as Apple Developer World at the time of the NeXT acquisition in 1996-1997. By 1999, it became Apple Developer Connection (ADC). It was shortened to Apple Developer for the 2010 Worldwide Developers Conference. The 2020 conference will be held online for developers at no additional charge.
