Describe the bug

Running swiftlint rules is throwing a fatal error. I'm using Xcode 11.0 and I believe the issue might be related to this version of Xcode or MacOS Catalina.

Complete output when running SwiftLint, including the stack trace and command used

Do you also get a similar failure when running swiftlint help? Printing the result of xcodebuild -version would be useful too. Finally, could you please share the results of running these steps?

$ git clone https://github.com/realm/SwiftLint.git
$ cd SwiftLint
$ swift run swiftlint rules

Thanks for your help. I rely on this information to diagnose the issue because I don't have a machine running Catalina available to me and haven't been able to reproduce this issue with Mojave and Xcode 11 beta 2.

When running xcodebuild -version I noticed the following error:

xcode-select: error: tool 'xcodebuild' requires Xcode, but active developer directory '/Library/Developer/CommandLineTools' is a command line tools instance

I referred to this thread on Stack Overflow and solved the issue. Afterwards, I was able to run swiftlint rules. I'm therefore closing the issue as it was an environment error.

Thanks for the help! 😄
