There were 45 directories found error

[plivesey]

I'm unable to generate a graph for any project.

Reproduce

1. Downloaded KSHMosaicCamera
2. Built and ran the project
3. From the visualizer folder, ran: ./generate-objc-dependencies-to-json.rb -s "" -D /Users/peter/Library/Developer/Xcode/DerivedData/ > origin.js (note, without the -D I get the error: find: /Users/peter/Library/Caches/appCode*/DerivedData: No such file or directory)

Expected

The graph generates

Actual

Output is:

I'm on Xcode Version 9.2 (9C40b). Is there anything I'm doing wrong?

FYI, here's my derived data setup:

Thanks for your help. This tool seems really useful.

It's not like an error, it's more like a warning, because you have never installed AppCode :)

Just run without > origin.js ./generate-objc-dependencies-to-json.rb -s "" -D /Users/peter/Library/Developer/Xcode/DerivedData/

And check the result.

If it's swift project, you can actually try to run with -w flag. Check here https://github.com/PaulTaykalo/objc-dependency-visualizer/wiki/Usage-examples

Thanks for the quick response. Running this on MosaicCamera again, I get the following result:

There were 45 directories found

var dependencies = {"links":[],"links_count":0,"objects":{}}

I saw this before as the content of origin.js. It seems like whatever project I run it on, it returns 0 objects. Is installing App Code a prerequisite?

[PaulTaykalo]

Nope, AppCode is just an alternative. So it this MosaicCamera your project that was being compiled last? Also, what language is it using and what Xcode version are you using? It seems that script cannot find any information about object being used by this project. (No infomration at DervicedData) driectory. You could try to clean up and recompile everything to check again. Should help. Otherwise, I would likely to see what you have in that directiory in DerivedData sript mentioning

[PaulTaykalo]

Hm.. it seems that is something broken at the moment. Will take a look, and will update you with results

[PaulTaykalo]

Heh. Fixed in https://github.com/PaulTaykalo/objc-dependency-visualizer/commit/4a4800b8c253ef81e43d74a4127bb3c9d8d6fe6c

You can try on your version by running it with ./generate-objc-dependencies-to-json.rb -o ""

or get the latest one from master

I think the same bug also exists for swift projects? Maybe not the same bug, but getting the same result:

1. Downloaded alamofire
2. Compiled alamofire

3. $ ./generate-objc-dependencies-to-json.rb -w -s "" -D /Users/peter/Library/Developer/Xcode/DerivedData/ > origin.js

   But origin.js was empty. It seems like it doesn't currently work on swift projects?

[PaulTaykalo]

It looks for objects in tests target. You should make sure that it looks to the main target instead, You'll need to either rebuild main target, or pass precise directory with object files via -p

[plivesey]

Yep, that was it. I wasn't able to find the object files before, but found it now. Thanks.
