As there are no changes to the existing format, there isn't a syntax converter for converting between Swift 5.x versions in Xcode. Since Swift 5.0 achieved ABI Stability, all new changes to the language are additive. Note: Xcode 14.3 converts your Swift code to Swift 5.8, even though the Swift Language Version dropdown under Build Settings shows Swift 5 ( learn more). To get an earlier version of Xcode, you can use your Apple Developer Account to download it from the Apple Developer Portal:įor more information on migrating to Swift 5, check Swift’s official blog, where you can also find migration guides for earlier versions of Swift. macOS Big Sur, the latest version of the world’s most advanced desktop operating system, is now available to Mac users as a free software update. But, as I said, you dont need to use the latest version of Xcode to develop/publish an app. To migrate to a newer version from Xcode, choose Edit -> Convert -> To Current Swift Syntax from the Xcode menu.ĭepending on your source code's Swift version, you might need a different Xcode version for the conversion. Having said all that, the latest release version of Xcode (9.4.1) requires macOS High Sierra 10.13.2 to run, so in that sense it does require the latest major version of macOS (although not the latest minor version).

Swiftify does not include a converter between different Swift versions because such a converter exists in Xcode.
