Feature request: cleaning Carthage cache

It's quite a nice idea, although it will require another folder access acquisition. I'll think about asking for the entire ~/Library folder, which then will make this trivial. Although I'm hesitant to ask about too much access from people, despite DevCleaner is open source, it could bring some security questions.

I'd also like to see that feature. I wouldn't mind another security question.

I'm still considering it, but as I said last year - I hesitate to ask users for even wider access to their files. In theory, access to entire ~/Library folder is giving potential access to almost entire user privacy. Of course DevCleaner is not doing anything wrong, but I always wanted it to be as safe as possible, for developers to trust it. It's a must.

I don't use Carthage so I'm not really aware about what numbers do we speak here 🤔 Is there no other way to clean its cache than to delete this folder manually?

In my case (only one project for not that many dependencies) that folder has 27 GB after 11 months of usage. When I look at DerivedData in there, it's one folder per Xcode version (6 in my case). In each of those folders there are between one and three folders per Swift version. And Rx alone takes about 860 MB per Swift version per Xcode version, about 8 GB total.

In case of deinstalled Xcode versions that data is not used anymore and I don't see any other way than to delete it manually - I'm not the greatest Carthage expert however.

Thanks for more details. It seems that indeed Carthage doesn't have such option itself. I'll keep this issue as an option for the future enhancement.

In overall: it's sad that more and more apps/software are not releasing their cache, which is a very bad practice. Not only Xcode, but many more.
