LLDB hangs at launch

[cbackas42]

I'm experimenting with using Nova for a SwiftGodot project, because I rather dislike VSCode. The short version of it is that this involved compiling a Swift .dylib via SwiftPM, then you launch Godot to test it.

So, I have a special debuggable version of the Godot.app (where I've resigned it and added the com.apple.security.get-task-allow entitlement). This definitely works, it can be launched and attached to with LLDB and I do so from VSCode and XCode alike currently.

In Nova, I configured it to launch:
~/Applications/Godot Debug.app/Contents/MacOS/Godot
And passed the appropriate parameters.

When I press Run:

• Godot launches and correctly.
• If a breakpoint was set in Nova, Godot instead hangs on startup forever - I believe the breakpoint is being hit, but the Debug panel is not showing it.
• The debug panel does say "Debug session is running" and shows a PID for the Godot process.
• Whether a breakpoint was hit or not, the Pause button in the Debug panel does not function, it produces the error message: Request “pause” failed: requestFailed(Optional("The operation couldn’t be completed. (SwiftLLDB.LLDBError error 1.)"), nil)
• Nova does not notice when Godot is quit via command-Q or otherwise - the Run task keeps spinning after the process has exited.

I'm getting the same behavior when trying to debug my own C++ applications. I really want to be able to use Nova, but this is preventing me from being able to. Please let me know if I can provide any info.

I got the "SwiftLLDB.LLDBError error 1" with my C Project.
Building the DebugAdapter & installing Icarus from github (see project description) fixed it for me!

Thanks for the info! I was able to build / load Icarus, and sure enough it actually runs, though it didn't take long before I managed to break it (crash while inspecting variables after pausing execution).

@logancollins Any chance this might get addressed? Thank you!

[GloryAlex]

Same problem. Does this project are still under maintenance?

[photex]

Just evaluating Nova after getting a new macbook. I really like many things about it, but without a functioning debugger I don't really have any reason to switch from Sublime or VScode or CLion or <insert your cool helix and lldb terminal setup here>.

If I can help here in any way I'd be happy to do so!
