According to [ios - Xcode 9 Swift Language Version (SWIFT\_VERSION) - Stack Overflow](https://stackoverflow.com/questions/46338588/xcode-9-swift-language-version-swift-version), this error means that your version of Swift isn’t supported by this version of XCode.

Indeed, according to [Xcode - Support - Apple Developer](https://developer.apple.com/support/xcode/), XCode 11.3 supports Swift 4, 4.2 and 5.5.
