Swift 5 Release Notes for Xcode 10.2

  • Starting with Xcode 10.2, Swift command line tools require the Swift libraries in macOS. They’re included by default starting with macOS Mojave 10.14.4. In macOS Mojave 10.14.3 and earlier, there’s an optional package to provide these runtime support libraries for Swift command line tools that you can download from More Downloads for Apple Developers. If you installed the beta version of this package, replace it with the release version. This package is only needed for Swift command line tools, not for apps with graphical user interfaces.

  • Swift command line projects won’t run on macOS 10.14.3 and earlier unless you install the Swift 5 Runtime Support for Command Line Tools package. Without that package, Swift command line projects crash on launch with “dyld: Library not loaded” errors. (46824656)
