A software development kit (SDK) is a set of development tools provided by a hardware or software vendor to allow their products to be used with those from other developers.[1]
History
From 1989 to the mid 1990s, Apple Computer was known for releasing SDK CD-ROMs to developers with comical pop culture references.[2][3] Apple has since moved their developer documentation online to the Apple Developer portal. In June 2025, Apple revised the various version numbers of its SDK and operating systems to unify them under "26", instituting an easier-to-remember major version number reflecting the subsequent year (after future releases).[4]
