It stopped working with Xcode 9. Even with the trick to unsign the binary and update the plugins the extension doesn't work anymore. I can see that the extensions are loaded (for e.g. Alcatraz appears in the Window menu) but the code map is nowhere to be seen.
This is most likely due to the fact that Xcode 9 reworked entirely the code editor component. It didn't seem that their extension framework was improved in Xcode 9 vs what they announced and showed in Xcode 8 so for now there is no way to get back the functionality in a more official way.
