If you develop on macOS and target Apple ecosystem (iOS, watchOS, tvOS, macOS), you will need Xcode as the Integrated Development Environment (IDE). You will also need Xcode or Xcode toolchain when compiling third party software on your machine. You can download Xcode from App Store if you somehow don’t have it installed on your machine. However, note that every Xcode release comes with minimum macOS version requirement that must be satisfied. In this article, we provide you with macOS version compatibility for all Xcode versions released by Apple, starting from Xcode 10. To build the compatibility table, we extracted and compiled data from Xcode release notes and Xcode system requirements .
